    Recently purchased a basement level condo in the Northeast (old building 100+ years). Am planning to put down engineered hardwood. Current “subfloor” is concrete. Portion of unit has 3/8″ solid hardwood glued down directly to the concrete and it has appeared to hold up well, thus I think concrete is relatively dry. The floors appear relatively level and I am interested in putting down this product. First of all, do you have any retailers in Mass? Second, do you see this being a good option, and do you think floating the engineered hardwood on top would work? Does the Tyroc have a firmer feel under your feet, or is it soft/squishy? Thanks.

    Hi there,
    I have read already that you can use tyroc as underlayment on concrete slab for 3/4″ nailed wood floor if you use 3/4″ plywood over tyroc. Tyroc floats on concrete, what about the plywood which goes on top? Does need to be attached somehow to tyroc? Does it need to be glued or screwed? I don’t want to create any conditions for squeaking
    nailed wood planks.

    • Doug says:

      Hello Gregg,
      You can use either glue down installation or nail down installation for your hardwood over Tyroc Subflooring. If you use the glue down installation you would glue your wood floor directly over Tyroc Subflooring. If you use the nail down installation over a concrete slab then you will need to install 5/8” or ¾” plywood glued down and fastened with screws to the Tyroc Subflooring and then nail down your hardwood to the plywood. In either case be sure your concrete slab is up to spec for flatness before you begin you installation. (3/16” over 10’ span).

      The glue down application helps to eliminate any potential for squeaking as it allows the wood to contract and expand as it naturally will due to its elasticity. This is what causes squeaking in wood floors is the eventually the wood flooring will expand and contract and over time loosens the nails.

  4. Brian says:

    We are planning to install carpet over this tyroc, i saw in previous posts that you can simply install the pad/carpet directly over thi Tyroc. Is it strong enough to hold down tack strips used in the carpet installation? it appears to me that they would just pull right out?

    • Doug says:

      Brian, apply PL Premium glue to the back of the tack strip before nailing it to the Tyroc Sublfooring panel. This will insure that the tack strip stays in place.

  5. Scott S says:

    I installed Tyroc and then the recent rainstorms have revealed a deficiency in the french drain and now I need to uninstall the Tyroc to allow the drainage solution company access to the wet area. What is the best way to uninstall? If possible I need to be able to resuse the Tyroc panels after the drainage company is done since the project is already skirting with over budget.


    • Doug says:

      As we discussed on the phone there is no need to uninstall the Tyroc Subflooring as it is impervious to water. To allow the drainage company to install whatever drainage is necessary (french drain, etc.) you can simply cut back the Tyroc Subflooring and re-install it or buy a few additional panels. The rest of your Tyroc Subflooring is certainly salvageable.

  6. Anil Rana says:

    I am debating in using tyroc for my subfloors vs 1″ xps foam board with 3/4″ osb board. What is the R-value of the Tyroc and what is the load i can put on it (psi per inch)? I plan on putting a pool table and am concerned the the tyroc subfloor can handle it?

  7. Bart says:


    I am considering Tyroc for my 1920’s Toronto house. Over top of the Tyroc, we would like to install tile. One of the advantages of Tyroc is it’s ability to deal with a floor that is not perfectly flat. I suspect this means if there when the Tyroc is installed, there could be a bit of motion in the Tyroc when walked on – for example, if there is a high spot in the cement floor, the Tyroc will flex as you walk next to the high spot.

    I know motion and tiles are a bad combination.

    What recommendations would you make for this situation? Do I need to have the cement floor redone? Are your “flatness” recommendations different depending upon what sort of flooring will be applied to the Tyroc?


    • Doug says:

      Tyroc Subflooring will cover over imperfections in the substrate. However, the substrate (concrete or wood) needs to be flat within a minimum of 3/16″ over a span of 8′ to 10′ feet. So if you have dips or rises in the concrete use a fill in patch to bring it up to specifications before installing the Tyroc Subflooring. Please use a poly-modified thin set and poly-modified grout when installing your tile flooring over Tyroc Sublooring.

  8. Chris says:

    I’m looking to use Tyroc in my basement where some other products which use OSB\chipboard concern me – my fish tank pumps sometimes go nuts and dump water everywhere from the top side of the product. I like the idea of non-absorbent subflooring. However I am way out on the west coast – is there a place to get Tyroc in Seattle or Bellevue WA area?

  9. Thank you and keep up a good work. Tyroc Subflooring solves moisture Issues in basements and above ground flooring.

  10. Renee says:

    Do I need a pad on top of Tyroc when installing carpet?

    • Doug says:

      Renee, yes you would install your pad on top of Tyroc as you normally would do for carpet installation. You can use a cheaper pad. Do not glue the pad to the Tyroc but install as you normally would over a wood substrate.

  11. Brian says:

    looking to install your product in my basement…..where can I get it? I live in Lancaster,
    PA. Also, I saw on another forum that you can paint Tyroc rather than cover it with another floor like laminate, etc. Is this recommended??

  12. Mary says:

    Looking at the pictures, Im curious just how much the concrete really can breath? It looks like the majority of the bottom would lay flush to floor except for the thin channels, but maybe the picture is deceiving? Other products appear to have more air space?

  13. Matt says:

    Hi Doug,
    I’ve read through the blod and have a question. I am working to properly insulate a crawl space. It has a dry, level and compact gravel/dirt floor and poured cement walls. The space is conditioned and is open to the larger basement area. There is no evdience of water infitration, but in the warmer months the humidity level in the crawl space seems to spike realtive to the rest of the finished basement. In the colder months, the crawlspace tends to be colder.
    Is it reasonable to install Tyroc over this type of ground surface? Will it provide a moisture barrier and some R-value to help with the humidity level and temperature in the crawl space.

    Thanks in advance,

    • Doug says:

      Hi Matt,
      Our Tyroc Subflooring product is not designed for this type of application. You may want to consider our Gorilla Shield product. It is made of recycled rubber and plastic. It comes in different thickness 1/4″ to 5/8″ and the 1/4″ can be bought in rolls 4′ x 25″ and the thicker products come in 4’x 8′ sheets. This product will provide a moisture barrier and R-value (this will vary as to the thickness). If you are interested you feel free to contact me.

      • Matt says:

        Thanks Doug, I sent you an e-mail about the GS. I also have a question regarding Tyroc. Do you have any experience with glue down flooring, like cork tile (not floating)? I notice you mention that there have been some issues with latex glues… would that incluce a latex contact cement? Also, will I have problems due to the light weight of the cork tiles?

  14. Marnie says:

    Last spring we did tryoc over concrete 900 sq ft under floating bamboo and ceramic tile (tap conned under the tile). Best floor ever. This year we want to redo the top floor, plywood subfloor (needs some serious leveling first), again floating bamboo and ceramic tile. Like the quiet of tyroc and the feel of walking on it, but is tyroc overkill for upstairs?
    Also, in Vancouver I had tyroc shipped from OK Builders in Kelowna. Is there a closer supplier this year?
    Oh, and what about stairs? Tyroc on stairs, or no?

    • Doug says:

      Hi Marnie, thank you for your comments. Actually there was no need to Tapcon the Tyroc under the tile as long as it was level. But what is done is done. Regarding your top floor plywood substrate. Be sure that substrate is solid i.e. has no deflection in it. As to the leveling yes it needs to be level up to specifications for your finished flooring. This can be accomplished two different ways. Level the substrate as needed before installing Tyroc or apply a self leveler compound over the Tyroc before installing your finished flooring. The Tyroc will add a sound barrier to your current flooring assembly as well as a moisture barrier and thermal barrier. It will protect your bamboo flooring from any moisture issues and provide the necessary underlayment for your tile application and installation. What finished flooring are you putting on your stairs? The Tyroc may not be necessary. Let me know where you are located and I will check with our distributor in western Canada. Thank you again for your comments.

      • Marnie says:

        The bamboo floor is solid strand woven, glue together floating install, and will be going on the stairs and landing. We are in a suburb of Vancouver (North Delta).

        • Doug says:

          Hi Marnie, installing Tyroc Subflooring under your bamboo flooring on your stairs and landing will work just fine as it will over the rest of your flooring upstairs.

  15. Bill S says:

    Can I use a Type I latex ceramic tile adhesive with Tyroc? I only need to tile a very small area near the entrance door and a 1 qt tub of ceramic tile adhesive is more convenient than mixing up a batch of modified thinset. I was looking at using Capitol CERA CT12 adhesive. Thanks.

    • Doug says:

      Bill, I can not recommend using latex ceramic tile adhesive. Tyroc has been tested with the Kerabond poly modified thin set and that has been proven in many installations with Ceramic tile. Tyroc has had some issues with latex based glues.

  16. Mike says:

    I would like to build my walls on top of the Tyroc panels. I know the panels flex and I assume the rubber base compresses. How much allowance for flex should I build into my walls? If my stud wall height is 8ft without Tyroc, what should it be with Tyroc underneath? Thanks!

    • Doug says:

      Mike, you can build your non-supporting walls on top of the Tyroc panels. The Tyroc does not flex that much the compression on the rubber mat is 76,000 lbs/sq.ft. Allow for 1/2″ as that is the height of the Tyroc. Your base plate needs to be anchored into the concrete floor. Let me know if you have other questions. Thank you for choosing Tyroc Subflooring.

      • Mike says:

        Thanks for your reply. I plan on insulating my poured concrete walls with 1.5″ XPS (seams taped/spray-foamed). Should the Tyroc run from foundation wall to wall and be made airtight with the slab? In this case, would I tape the Tyroc seams and spray foam the perimeter against the wall?

        Or should I create an air cavity that ties the space (minimal) behind the XPS to the space below the Tyroc?

        Or should the air below the Tyroc ventilate to the cavity between my rigid foam and my finished wall? I will finish my walls with acoustic panels so they will be highly permeable to vapor.

        Ultimately, I guess it’s a choice between having an airtight layer with equalized vapor pressure to the outside that might have permanent moisture (that is harmless?); Or, having connected cavities that continuously wick moisture to the finished interior space from the outside. I’ve read arguments in favor of both. What do you suggest?

        • Doug says:

          Mike, Tyroc can run wall to wall. I would not tape the perimeter in the attempt to seal up your space. Particularly in a basement environment it is best to allow the space to breath. Permanent moisture in any space is going to turn into trouble with mold or mildew. Allowing for air to flow helps to let the space dry out as well as a good HVAC system that controls the humidity.

  17. Dave says:

    Perhaps I have not noticed the response, but I do not see anywhere that there is any glue applied to the first row of tyroc next to the wall on the bottom side of the panel.
    If not, does this mean the floor is floating?

  18. john says:

    Would you install the Tyroc flooring before or after painting the basement?

  19. Ted says:

    I have finished installing tyroc in my basement. I have a 55″ projection tv that is fairly heavy and on wheels. The TV is currently in a storage room that doesn’t have tyroc. Should I be concerned about damage to the tyroc when I roll the TV out of storage onto the tyroc? The TV has 4 wheels and weighs ~250 lbs.

  20. Dennis says:

    Tyroc is made from rubber tires and used plastic bottles. I’m most concerned about leached fumes from these plastic bottle and rubber products. Could you comment on that?

    • Doug says:

      Dennis, Tyroc Subflooring has no off gassing (leached fumes) from the recycled post consumer plastic and recycled rubber tires.

  21. Ted says:

    Is it really acceptable to use ceramic tile directly over Tyroc? It would seem the flexible/floating nature of the material would cause at least grout cracking and maybe worse. Are there any installations of tile over Tyroc in a basement that you can refer to or references that you can show that this isn’t a concern? I read the test report of the Robinson-Type floor tester and that doesn’t sound very good that after 3 cycles there was a broken tile and broken grout joint. How does this compare to other underlayments for tile in a basement? I really want to use Tyroc because it has many good features but I’m worried about tiling over it.

    • Doug says:

      Ted, yes it is acceptable to tile directly over Tyroc using the recommended thin set and grout. Please refer below to two testimonials from a consumer and contractor and you can go to our website showing more testimonials and actual installations of tile over Tyroc on our website. These installations include Tyroc Subflooring and ceramic tile installations over both concrete and wood substrates (and both below grade and above grade).

      Please note that Tyroc did meet the standards and rating for Residential “Kitchen, Bathroom and Foyer” applications of ceramic tile over Tyroc in the Robinson-Type floor tester. This test is a destruction test. The purpose of the test is to determine at what point does the total assembly fail and to what standard the assembly meets the testing standards (or rating) according to the TCNA (Tile Council of North America).

  22. Dave says:

    Are you suppose to seal the edges that meet the walls to the concrete floor with anything to get an airtight space between the floor and the tyroc or is it not suppose to be airtight? Planning on leaving a bit of space so that I can nail a tack strip for the carpet.

    • Doug says:

      Dave, there is no no need to seal the edges that meet the walls. You can butt the Tyroc up to the walls. Using the PL Premium glue (same glue as you use for the seams of the panels) glue the back of your tack strip and then nail directly to the edge of the Tyroc panels.

  23. Brynne Jones says:

    I have three questions:
    1) Where can I purchase Tyrok in Prince George, B.C. ? (approximately 1200 square
    2) Will Tyrok support a home gym with two 300 lb. weight stacks (the gym is set on
    5/8″ rubber mats) ?
    3) The Tyrok will be installed over an area that contains a basement floor drain that is
    sloped and somewhat sunken from the basement floor level. Is there a method
    using an inorganic material to support the Tyrok that will solve the problem and still
    allow water to flow into the drain ?

    • Doug says:

      Brynne, I will have to check with my distributor in B.C. to see if they have a dealer in Prince George. It may require a delivery from the closest location.
      Tyroc will support your home gym. Tyroc Subflooring is flexible and will conform to your basement slab, the grooves on the bottom allow access water to flow to the drain. You will want to level the concrete floor to an acceptable level (within an 1/8″ tolerance) up to the drain. At the drain area you may need to install a separate grate over the drain to support the Tyroc to avoid any failure in that area and still allow for the water to flow into the drain.

  24. Josie says:

    Thanks for your blog and the opportunity to ask questions!

    We’re interested in using Tyroc in gutted subgrade kitchen and laundry areas. Please advise whether we should run Tyroc on the slab and then install cabinets, or install cabinets and then run Tyroc up to them?

    Based on the thermal raise you have described your product as providing and the fact that cabinets are adjacent to exterior walls in some places, it would be nice to have that in the whole floor surface, and not just up to the base cabinets- which will of course also be attached to the walls..

    Thank you.

  25. Billy says:

    I will be buying this product for my basement floor. I would also like to use MgO board for the walls, but cannot find a supplier. Your product is basically MgO board glued to the recycled material. Would you also sell just the MgO board itself? If not, can you direct me to suppliers of MgO board in the Northeast?

    • Doug says:

      Billy, check with Marjam Supply that sells our Tyroc Subflooring. I believe that they also sell a MgO board for walls. Locations for Marjam Supply are on our website just click on Marjam logo.

  26. Ted Browning says:

    I am finishing my basement and I want to install Tyroc first and then do the interior non-load bearing walls. Is there a risk of damaging the Tyroc while finishing the rest of the space with drywall, etc.?

    • Doug says:

      Ted, Tyroc Subflooring will hold up while you finish out your space with drywall etc. However you may want to consider purchasing our Gorilla Shield product to protect the Tyroc from spillage while you are installing and tapping your drywall. Where are you located? Or you can use other types of flooring covering protection.

  27. Alex says:

    I just purschased the Tyroc subfloor for my basement. Could you recommend a specific constructions adhesive that is low to no VOC? I was thinking of gong with the TiteBond Green Choice brand but wasn’t sure which one to use. They do have a subfloor version but I couldn’t confirm if it would be appropriate on rubber. If you have any other recommendations, please advise.

    • Alex says:

      Also, how many tubes would I need? I ordered 87 Tyroc pieces.

      • Doug says:

        Alex each Tyroc panel has 5.33 linear feet of overlap seams that require coverage. Take the # of panels in your installation x 5.33 and divide by the total coverage of your tube size.
        For a 10 fl. oz. cartridge:
        A ¼” (6 mm) bead extrudes approximately 30.6 ft (935 m).
        For a 28 fl. oz. cartridge:
        A ¼” (6 mm) bead extrudes approximately 85.8 ft (26.1 m).

    • Doug says:

      Alex, the recommended construction adhesive for Tyroc Subflooring panels is PL Premium.
      Loctite® PL® Premium® Polyurethane Construction Adhesive is a one component, polyurethane based, moisture-curing adhesive. It is VOC compliant and contains no chlorinated solvents or water. Loctite® PL® Premium® provides superior adhesion to most common construction materials. It can be used for interior or exterior projects and is 3X as strong as ordinary construction adhesives. It is also waterproof, paintable and cures even in cold temperatures. Ideal for sub floor installations.

  28. Jon says:

    Hope you’re not sick of these questions, but is there anywhere around Winnipeg to get tyroc?

    • Doug says:

      Jon, we always want to direct customers to where they can buy Tyroc Subflooring. In Winnipeg please contact any building supplier and let them know they can get Tyroc Subflooring from Lancashire Distributors.

  29. Ken says:

    How durable is the surface of the tyroc. I’ve got a 3-5 yr basement development plan and since tyroc is the first step am a little concerned abou walking on it for a long period of time.

    • Doug says:

      Ken,Tyroc Subflooring surface will hold up to normal traffic walking over it for long periods of time. However, it is not meant to be a finished flooring surface. Be sure you use PL Premium glue on the seams.

  30. Andre Tremper says:

    I am in Richmond VA. Were can I buy Tyroc

    • Doug says:

      Andre, You can order Tyroc Subflooring from Marjam Supply. They can deliver it to your location. Please refer to their locations that are closest to you. Or you can call or email me direct and I can help direct you. Just go to our contact page on our website or click on the Marjam logo for locations.

  31. Mark Spadaro says:

    Can Tyroc be used as 1st floor subflooring laying across wooden floor joists? Or will it buckle/crack when walked upon? Also, why don’t you have an 800 # for better info disbursement?

    • Doug says:

      Mark, Tyroc Subflooring is not designed to be used over wooden floor joists. It requires a substrate either a wood substrate over floor joist or concrete slab.

  32. TonyP says:

    The plan is for applying Tyroc over a basement slab, then electric radiant heat and to finish a engineered wood floor.
    What preparations are required between layers in order for a sound installation?

    • Doug says:

      Tony, electric radiant heating systems can be installed over Tyroc Subflooring. Please refer to the engineered wood flooring manufacturer for proper preparations between the radiant heating system and the engineered wood flooring product.

  33. Kevin says:

    What temperature increase can I expect from this project on a concrete basement floor?

    • Doug says:

      Kevin contractors and home owners have reported a 10F + increase in their floor temperature and over all space temps after installing Tyroc Subflooring.

  34. Jay says:

    Starting a basement finishing project and would like to install tyroc sub-floor. I will be insulating the concrete walls with 2″ rigid foam board. Do I install the rigid foam board first all the way to the concrete slab and then run tyroc to up to the foam board, or should I first install the tyroc sub-floor up to the concrete wall and then install the foam board on top of the tyroc? Or does it not matter?

    • Doug says:

      Jay, you can do it either way. I would first install the Tyroc and then install the foam board to prevent any wicking of moisture up into your foam board.

      • Jay says:

        Thanks… Next question. I will be framing on top of the tyroc. How to I fasten the bottom plate. Just to the tyroc, or all the way through to the concrete slab. Can I use Ramset nails with .22cal shot or do I have to use tapcon screws?

        • Doug says:

          Jay you need to fasten your bottom plate all the way through to the concrete slab. You can use Ramset or Tapcon screws. Tyroc will protect your bottom plate from any potential moisture and mold issues. It will take a nail or a screw but will not secure it. So it is necessary to go into the slab for securing.

          Out of curiosity where are you located and how big is your project?

      • Kate Leslie says:

        Jay, I’ve been mulling over this same issue whether to run the rigid foam down to the concrete slab or just on top of tyroc.

        If you install the Tyroc wall to wall first and then the rigid foam board to rest on top of it, then wouldn’t moisture seeping through the walls trickle down to the top of the tyroc and have access to your bottom plate wood/tacking strips/carpet?

        • Doug says:

          Kate, if you are installing non load bearing walls on top of the Tyroc and running the Tyroc Subflooring wall to wall you can leave a small gap at the wall to allow the excess moisture seeping through the walls to run down and under the Tyroc. The moisture will follow the path of least resistance. The gap need not be more than 1/8″ – 1/4″.

  35. Craig says:

    Hi there – I would like to install a tongue and groove hardwood floor in my basement over top of Tyroc which is placed directly on the slab… I believe this floor requires nails… what is the recommended approach?

    • Doug says:

      Craig yes you can install hardwood flooring over Tyroc in your basement. Tyroc Subflooring will protect your hardwood floor providing the moisture barrier you need. There are two installation methods you can use for your hardwood flooring. Glue down installation or nail down installation. If you use the nail down installation you will need to install a 3/4″ layer of plywood over the Tyroc Subflooring to allow for the nail to anchor. The glue down installation eliminates the need for the plywood layer. In both cases be sure your concrete floor is level as the Tyroc will conform to the concrete substrate. If needed bring the flooring substrate up to spec by using a self leveling patch in any low spots over the Tyroc before installing either the plywood layer or gluing down the finished hardwood flooring.

  36. Mark says:

    I like the recommendation to build non load bearing (e.g. perimeter basement walls) on top of Tyroc. If I understand correctly, then it sounds like installing Tyroc would be the first step in my basement construction (followed by walls, plumbing, electrical, insulation, drywall etc.). My only concern is will Tyroc hold up to all the construction traffic (boots, ladders, material piles) by the time I get to the wood floors at the end? What about dust getting in the cracks? Should I cover/protect the Tyroc during construction?

    • Doug says:

      Mark, Tyroc can take a good bit of abuse but I would recommend depending on how much construction you will be doing that you consider our Gorilla Shield product to help protect your Tyroc Subflooring during finish out construction. It comes in 48″ x 25 ft rolls of 1/4″ thickness see our website for more information and if you are interested contact me for pricing.

  37. Albino DiLeonardo says:

    can you tell me if I am able to purchase this underflooring in the Kitchener Waterloo area?

    • Doug says:

      You can purchase Tyroc Subflooring from TimBr Mart in Tavistock and they will deliver to your project site. You can also purchase Tyroc from Turkstra Lumber in Cambridge and they deliver as well. Or you can go to your local Home Hardware Building Center store and they can order it in if they are not stocking it.
      Let me know if I can be of more help.
      Thank you.

  38. Elisabeth says:

    Where can I get this in or around St Paul AB (2 hrs east of Edmonton)?

    • Doug says:

      You can purchase Tyroc Subflooring from TimBr Mart in Calgary or Edmonton.

      • elisabeth says:

        Hi Doug,
        I tried calling Edmonton tim-br mart about your product and they said they had never heard of it and dont supply it. Any other dealers in edmonton?


        • Doug says:

          Elisabeth, Tim-Br Mart or Timber Town can get Tyroc Subflooring through Lancashire Distributors. If you need further help please email or contact me direct by going to our contact page on our website and I can help you find a source.

  39. Scott says:

    What about porcelain plank tiles? I haven’t found any mention of these on your site.

    How about heavy metro wire shelves on casters. I’ve seen some floor products that suggest minimum wheel diameter of 2 inches. Will Tyroc support lesser diameters?

    Also, a post below mentions the flexibility of tyroc, and that dips in the foundation wouldn’t be a problem if using ceramic tile, because the weight of materials will bring tyroc down to foundation before it solidifies. So, what if using floating click-style wood/bamboo planks, where there’s less weight? I’m concerned about the click joints flexing too much, weakening the joints. We have a floor that’s not easy to level, so I was initially interested in the tyroc’s ability to go over minor height variances.


    • Doug says:

      Scott, Tyroc will support your porcelain plank tiles and any fixtures that you install over your finished flooring (provided that your finished flooring supports the fixture). Tyroc Subflooring conforms to the substrate. Your substrate needs to be brought up to the specifications required by the finished flooring product. Tyroc Subflooring will go over minor height variances and help level out the floor, however this is dependent on your definition of minor height variances. Most finished flooring requires the substrate or subflooring to be within a tolerance of less than 1/8″ over a 8′ span. A self leveling patch may be required to bring your substrate up to specifications.

    I am also looking for Tyroc in Calgary as a post back in June that was not answered. I also contacted some of the suppliers on your website, but none knew of your product or that they offered it.

    Are there any suppliers out in Calgary? If not, are there any that are nearby that I could get them to ship to me? Do you know the cost of the product out here? I would need about 800 sq feet.

    Also is this product ok to install in an electrical room, and what kind of space should be left around hot water tanks and a furnace if necessary.

    thanks so much,

    • Doug says:

      Ken Tyroc Subflooring is available through TimberTown or Windsor Plywood in your area. When you call ask for the contractors desk. If they don’t tell you they don’t know about it ask for the store manager as they can order it in from the distributor there. You will have to check with them on pricing. In terms of the space to leave around your hot water tanks and furnace just lay up the Tyroc up to area around them. Tyroc will not be affected by either.

  42. Anne says:

    I am laying floating hardwood planks on top of tyroc. I am just wondering is better to lay the planks perpendicular or parallel to the longside of the tyroc orientation.

  43. Gus says:

    I am planning to install 620 sq ft of Tyroc with vinyl plank floor on top. I am concerned about trapping humidity and moisture in the air under the Tyroc which defeats the purpose of allowing the concrete to breathe and stay dry. Do you recommend installing perimeter ventilation grilles to allow ventilation of the airspace below the Tyroc floor? Dricore seems to recommend a grille every 10 ft around the perimeter.

    • Doug says:

      Gus Tyroc Subflooring is designed with air flow channels in the diamond pattern of the underside of the panel to allow movement of air over the concrete. This also allows for access moisture in the event of minor leakage from your walls if it were ever to occur to flow to your drain or sump pump. We do not recommend ventilation grilles on the perimeter as they are not needed or required.

  44. Jon says:

    I am planning to finish a basement in St Louis. Approximately 2500 sq ft. I plan on using 2″ rigid foam on the walls, foundation top to sill plate and rim joist using spray foam to seal joints. I also see you recommend building non load bearing walls on the Tyroc. So my question is what is the best practice for the tyroc and foam board interface? I think i should run the tyroc up to the wall first, then foam board outside wall on top of the Tyroc. But do i seal the tyroc wall intersection? I know i will need to seal the tyroc foam intersection.


    • Doug says:

      Jon, yes you can run the Tyroc to the wall and you can seal the Tyroc wall intersection.

    • Gene says:

      I am in the process of a basement remodel in St. Louis, MO. Want to install Tyroc over concrete floor. Where is it available for purchase near St. Louis, MO?

  45. Tom says:

    Carpet on Tyroc.

    How much space to leave between edge of Tyroc and wall to allow placement of carpet tacks? This is a follow up question to the recommendations on placing the tack strip directly on the concrete and not through the tyroc and into the concrete. I guess it would depend on the width of the tack strip but what thickness is too thick — what if the tack is 1.5 inches wide, is it okay to have this gap all around the perimeter? Will it affect the ‘integrity’ of the subfloor? Thanks

    • Doug says:

      Tom, the carpet tack strip can be applied directly on the Tyroc surface board. You will need to glue the tack strip to the Tyroc with a construction glue. We recommend PL Premium. Glue the tack strip and nail as normal the tack strip to the Tyroc surface board.

      • Tom says:

        Hi, Thanks for the reply. To be clear, the carpet tack strip goes on top of the tyroc and not directly on the concrete? So there is no need for a gap between the tyroc and perimeter wall to allow carpet tack strip to go directly on to the concrete? This was mentioned in one of the blog answers.
        If the tack strip is on tyroc, does the strip have to be nailed/screwed through the tyroc alone or through tyroc and into the concrete base/floor also?

        • Doug says:

          Yes the tack strip goes on top of the Tyroc Subflooring and not directly on the concrete. There is no need for a gap between the Tyroc Subflooring and perimeter wall. Use the recommend method of installing the tack strip to Tyroc Subflooring as outlined below. The tack strip does not need to be screwed or nailed into the concrete.

          Install the Tyroc Subflooring butting the edge of surface board to the wall. There is no need for a ¼” expansion joint as Tyroc Subflooring will not expand or contract with temperature changes. To insure against any breaking of the surface board overhang on this edge when you hammer in the nails of the tack strip trim back the surface board to the rubber underlayment.

          Apply enough construction glue (we recommend Loctite PL Premium) to perform a good bond between the tack strip and the Tyroc Subflooring surface board.

          Install the tack strip to the Tyroc Subflooring surface board as you normally would if installing the tack strip to a wood subfloor.

  46. Ronald Martinez says:

    Need help, I am getting ready to do a carpet install over Tyroc. The Tyroc is already installed. How do I secure the tackless strip. I have been told I cannot nail the tackless into the Tyroc as they will not hold. I use a Pam Hotmelt Thermoplastic system to secure tackless strip to substrates that I cannot nail to, ie: heavy aggregate concrete, wood subfloors that my customer does not want nails in etc, sometimes I will use a heavy construction adhesive, are either one of these methods OK for installing the tackless if I cannot use nails. Also, it occures the me, using nails in the Tyroc may negate its moisutre barrier properties

    • Doug says:

      Ronald you can use most any adhesive that bonds to the wood tackless strip as the MgO board bonds to most anything. We recommend the PL Premium. The nails in the tack strip if less than a 1/2″ will not penetrate through the rubber backing so you won’t negate the moisture barrier however the MgO board will not hold a nail.

  47. 2oolman says:

    Is applying ditra over tyroc overkill ?
    Is tyroc affected by the use of heating cables/mats ?

    • Doug says:

      Yes Ditra over Tyroc Subflooring would be overkill. Tyroc Subflooring is your moisture barrier, de-coupling and crack isolation barrier, as well as your underlayment all in one for your tile installation. Tyroc is not affected by the use of heating cables/mats. Be sure to install your cables or mats over the Tyroc not under it. Tyroc will help improve the efficiency of your radiant heating system as you will not loose your heat transfer down.

  48. Pat says:

    When installing, do i build my 2 x 4 stud walls on top of the tyroc to allow air flow or do i nail the walls to the ground and butt the tyroc up against the edge of the walls?

    • Doug says:

      Pat we recommend installing Tyroc Subflooring to the perimeter of the space and building your non-load bearing stud walls on top of the Tyroc Subflooring. It will protect your stud walls from wicking up any moisture and developing mold or mildew. This will also keep your finished walls off the concrete and protect them as well from wicking up any moisture from the concrete floor. Tyroc Subflooring does not expand or contract so you can butt up to the perimeter walls there is no need to leave a gap but you don’t have to be tight either allow for easy installation.

      • Nick says:

        Hi, I am planning on building non-load bearing walls on top of Tyroc in my basement. There is some minor pooling in one section of floor where it meets the cnider block wall. If I do as you recommend, is there any possiblity of water coming up around the nails holding the plate down and getting to the plate?

        • Doug says:

          Nick be sure you are anchoring your plate into the concrete. Tyroc Subflooring will not hold a nail. I suggest you use tapcon screws to anchor your plate by drilling the hole through the plate and sealing the head of the screw with silicon sealer.

  49. Peter Tinits says:

    We would like to install a hardwood look-alike Armstrong vinyl plank floor and a Tyroc subfloor in our basement which is currently carpeted. I presume we would first rip out the carpet. I read on your website that almost any flooring can be installed directly over Tyroc. I don’t want to raise the floor overly much. Can vinyl planks be installed without plywood underneath? We have an older large screen rear projection television that might weigh 500 lb. Will this be a problem without plywood?

    • Doug says:

      Yes Peter you can install vinyl plank flooring directly over Tyroc Subflooring in your basement. Tear out carpet before installing Tyroc Subflooring. No additional plywood is needed. And yes the Tyroc Subflooring will easily handle your large screen TV.

  50. A says:

    We just had a Tyroc subfloor installed over a concrete slab which had been levelled. We have noticed that at least half a dozen of the Tyroc panels have a noticeable flexing as you place weight on them – the centre of the panel moves up and down. We are planning on installing tile over the Tyroc, but we are concerned that the up and down movement of the Tyroc will cause the tiles and/or grout to fracture. Is there a way to secure the panels to the concrete slab?

    • Doug says:

      The weight of the thin set and tile will settle the the Tyroc Subflooring to the contour of your basement floor. If you are concerned you can use Tapcon screws to tighten the panel down in the areas of concern. If you would like to you can send me pictures of these areas and I can review further. Please send them to dweber@bjetinc.com with your contact information. Be sure to install your tile as recommended by the manufacturer and use a modified thinset and modified grout for your installation.

  51. Tom says:


    I live in Kansas city, Kansas 66213 zip code. Where can I buy Tyroc from?

  52. Ed says:

    Hi Doug, can you tell me if there are any Home Hardware Store that carries Tyroc near Markham area? I would like to see if they have it in stock so that I can see the product before purchasing it to finish the basement floor. Any suggestions are appreciated…


    • Doug says:

      Ed there are several locations in and around Markham. Please call the location nearest you and if they don’t have enough product in stock they can bring it in for you.

  53. Chris says:

    I live in Calgary, AB and was just wondering where I can order Tyroc for my basement.

  54. Tom Richards says:

    I am wondering if I can use Tyroc in place of Kerdi or Cement board + 6 mil on the walls of a bathroom

    Many thanks!

    • Doug says:

      Tom, Tyroc Subflooring is a subflooring and underlayment product. It is not designed for use on the walls in a bathroom or shower stall.

  55. Anne Mollo says:

    I want to insulate the concrete floor but still allow it to breathe and evaporate moisture. A DriCore system has a good air gap beneath the moisture barrier, but it’s not clear to me that the “channels” in a Tyroc system will function the same way. We don’t have big moisture problems and the basement slab is not graded toward the sump well, it’s more flat, and our concern isn’t so much with flooding but with the normal respiration of the slab and allowing it to breathe.

    Secondly, the only flooding that might occur is from appliances in the basement (washing machine, for example). In the event of a flood, would we need to tear up the Tyroc subfloor in order to dry things out?

    • Doug says:

      Anne Tyroc Subflooring was designed to accomplish just what you are looking for. It allows the concrete to breath as well as creates an air flow to help dry any excess moisture due to the concretes normal sweating. With its ship lap seam it is easy to install and creates a moisture barrier as well as thermal and sound barrier. Tyroc is impervious to water and moisture so in a major water event such as a flood or appliance malfunction causing flooding you would not have to tear out Tyroc. It will not swell or absorb moisture and will not feed mold or mildew.

      • Anne Mollo says:

        Well! We installed a Tyroc subfloor and have been loving it. However, as I predicted (!!) we did have a minor flooding event here just last night. The Tyroc kept most of the finished portion of the basement safe and dry, but close to where the water came from, the subfloor did get wet and there was enough water to also wet the carpet tiles on top of the subfloor. The tiles are out and drying now (easy; we can re-lay them later) and we’re using fans to dry the Tyroc. Do I need to worry about the water that is surely trapped under the subfloor? Or will that evaporate up as well? Is it necessary or worth it to pull up that small area of subfloor to dry the slab?

        • Doug says:

          Just mop up any excess water over the subfloor and let it dry with out fans. The surface board will not absorb moisture. Any moisture trapped under the subfloor will eventually evaporate as the channels in the subflooring will allow air flow. If you are concerned you can use a hole saw to cut a 2″ hole and use a shop vac to suck any excess water from under the subfloor and reverse and blow any additional moisture then replace the plug (the 2″ piece) back into the panel and seal with some silicon glue. However if you have a drain in your basement floor this is not necessary. \

  56. rick says:

    Can the Tyroc tiles be reused if I need/want to remove the tiles for some reason, such as an unexpected pooling of water? My 30 year old house shows no sign of water problems but it would just be good to know. I am assuming that with the adhesive the tiles would just be throw away. Perhaps, could I just butt them along the cut lines that I would have to make and glue down some thin plywood?

    • Doug says:

      Hi Rick, I’m not sure I understand your questions and may need more clarification. However, as I understand it you are concerned about unexpected pooling (possible flood)of water and if you can reuse the Tyroc Subflooring? The answer would be yes. Tryoc is impervious to water. Tyroc is a floating subfloor system so is not adhered to the substrate surface (concrete or wood substrate above ground). If you have glued your finished floor covering over Tyroc and the finished floor covering was not salvageable you would simply pull up the area affected and replace with new Tyroc panels and recover with your finished flooring. If this installation is in a basement I would not recommend using any plywood or OSB board in your installation at any time.

      If you are suggesting that a pooling is taking place due to sump pump failure or drainage failure once again you will be able to pull up the Tyroc Subfloor to get to the problem, fix the problem and replace the Tyroc Subflooring and your finished floor covering. Please let me know if I have addressed your questions or need more clarification.

  57. N says:

    1. The concrete slab in my basement has some sort of paint or sealant on it. Does this need to be removed prior to installation of Tyroc?

    2. If Tyroc is installed inside (rather than under) framing for drywall, does it need to be tied to the gasket under the wood framing to make a complete seal? If so, how is this accomplished?

    • Doug says:

      You do not need to remove the paint or sealant. Tyroc Suflooring is butted up to the wall no need for an expansion gap it will not expand or contract. Please let me know if this addresses your questions.

      • N says:

        So why do the installation instructions (on your website) recommend leaving a gap around the perimeter?

        • Doug says:

          Thank you for pointing this out. After reviewing the posted instructions I did see some information conflict and will edit this document to be consistent. A 1/4″ gap is not necessary, but you can if you wish to.

  58. SueK says:

    I am looking at getting some Tyroc for our basement. I live in Cornwall and can’t seem to find any here. Can I order it through the Rona here?

  59. Roy A. Mura says:

    Can I get this product in the Buffalo, New York, area? We are finishing our basement and I’m considering putting Tyroc down before carpeting. Thanks.

    • Doug says:

      Yes Tyroc Subflooring can be delivered to Buffalo, NY for your basement subflooring and underlayment for not only your carpet but any other finished flooring you want to install.

  60. Ed Smith says:

    When using Tyroc and tile in a basement bathroom, is it OK to mount the toilet and bathtub on top of the Tyroc and tile?

  61. Ed Smith says:

    I’m installing Tyroc in my basement which will have carpet & ceramic tile. This is a new project and the Tyroc will be laid first and then the interior walls built in top as you recommend. I have a few questions.

    1. What is the recommended way to install carpet over Tyroc. Do you just glue the tack strips to the Tyroc or can they also be nailed?
    2. When installing a tub and toliet in the bathroom should they be install on top of the Tyroc & tile?
    3. I have some storage areas that I did not plan to finish the floor. What sort of transition should I install from the Tyroc to the bare concrete floor?


    • Doug says:

      1. We recommend a bead of PL premium be used under the tackstrip then drive the nails in to secure it while it cures.
      2. I would recommend that the tub and toilet be installed on top of the Tyroc. It will make the tiling much easier.
      3. A small piece of corner moulding and some construction adhesive can do a reasonable job as a transition. Most DIY stores have corner mould with 1/2 depth. You may want to reconsider and cover your storage area with Tyroc. It will help protect any thing stored directly on the floor from moisture and insects.

      Hope this helps.

  62. Marnie says:

    800 sq ft of wood over Tyroc is excellent. We’re worried about setting the tile over Tyroc in the bathroom, though, because of the flex in the floor. Will it crack the grout? Also, what thinset and grout do you recommend? I see that in the TCNA report they used ‘custom Versabond fortified thinset mortar’ and ‘custom premixed grout’. What exactly is that? The floor guys are trying to steer us towards vinyl click together tile instead of grouted ceramic tile to avoid problems, but I’d really like to try the ceramic installation.

    • Doug says:

      Marnie no need to worry. Tyroc has been tested by the Robinson Flooring test and has met the ASTM standards for tile application over Tyroc in Residential Bathrooms, Kitchens, Foyers.

  63. Tom says:

    Just saw a youtube which shows the guys stapling and using PL400 on install of tyroc. Believe your info just advises the PL400 adhesive. Which is correct?

    • Doug says:

      Tom, this is an older video. Stapling in not required. We recommend PL Premium as it has less smell when used in an enclosed environment such as a basement.

  64. Jonathan says:

    We are replacing our basement staircase at the same time as putting down a Tyroc subfloor. Do you recommend building the staircase on top of the Tyroc or directly on the concrete floor?

    • Doug says:

      Jonathan, non supportive (dividing) wall structures can be installed over Tyroc Subflooring. However you have a supportive structure with your staircase and I would recommend that structure be secured directly to the concrete floor.

  65. Marnie says:

    It was hard to find Tyroc in the Vancouver area, but I had a pallet (152 tiles) shipped from Kelowna for a very reasonable shipping charge from:
    OK Builders Supplies Ltd
    1095 Ellis St.
    Kelowna, BC, V1Y 1Z3
    Fast, friendly service. They really go the extra mile.

    We just laid the first room tonight over slab on grade. It went down fast and smooth, cutting easily. Half the bamboo floating floor is in. What a huge difference between standing on this floor and standing on the laminate over foam in the next room. This feels like a real wood floor! It also passes the dog toenail test: dachshund running over bamboo is nice and quiet. Tyroc is worth the expense for ultimate comfort and how liveable the rooms will be.

    We’re using PL400 instead of PL Premium. This won’t cause any issues?

    • tyrocdoug2 says:

      Marnie using the PL400 should not cause any issues. Sorry it was hard to find we are working hard at expanding our availability of Tyroc throughout North America.

  66. Tom Lich says:


    And thanks for the prompt reply. Have contacted the store for an order.

    Another question: Will I need the standard underlayment that laminate flooring advises or will your top layer suffice?


    • tyrocdoug2 says:

      We recommend following the finished flooring manufacturers requirements to meet their warranty requirements. Often times they require a minimum underlayment so as not to void their warranty. You can go with the minimum underlayment requirement as Tyroc Subflooring provides the moisture barrier, thermal barrier, and comfort. It is also mold and mildew proof and provides that protection to your finished floor covering as well. There is no reason to upgrade the minimal required underlayment as Tyroc provides all of the upgraded underlayment features.

  67. Tom Lich says:

    Great product as I have been researching this topic for some days and was frustrated by the complex and pricy systems that did not seem to work.

    One question: I will install this over a concrete basement floor laid in 1947 that shows no standing water or any weeping to date-except what appears to be a very short termed leak from a basement window. Plan on using a laminate floor over Tyroc. What experience do you have with these systems with some accidental seepage from a basement window etc. Does the Tyroc allow the water to eventually dry and diffuse to the surface slowly or is it trapped there.

    Also would be grateful for a local supplier in the Portland Oregon area.


    • tyrocdoug2 says:

      Hi Tom,Tyroc Subflooring is now available in Portland through Green Depot at 819 SE Taylor Street
      Portland, Oregon (503) 222-3881. Tyroc Subflooring is designed to handle the occasional seepage from your basement walls or windows as the water will travel down the wall to the floor. Tyroc is designed to allow for flow of excess moisture to your basement drain (sump pump) and protect your finished floor for any moisture exposure coming from your basement concrete slab. You will also find that with Tyroc Subflooring your finished basement flooring will be warmer and quieter as Tyroc is a moisture, sound and thermal barrier all in one. Perfect for laminate flooring installation in a basement.

  68. Jason Messingham says:

    Any place in the Denver , Colorado area to order Tyroc?

    • tyrocdoug2 says:

      Hi Jason thank you for your interest in Tyroc. Yes we have distribution in Denver, CO. And when you are ready to order for your 3500 sq.ft. project please let me know and I can direct you to the proper contact in Denver. Thank you for your comment in your last email as well.

      “Yes you are. That helps in the planning. I will contact you when ready to order or if the city has any questions. You’re product is exactly what I want.”

  69. Judy says:

    I have a customer that put tyroc in his basement. We are looking at putting carpet over it. Is it ok to power stretch the carpet in? Concern is if the floor will lift with that kind of pressure? What is recommended?

    • Judy says:

      I am still awaiting an answer on my question. I do have a customer awaiting a response from me. Could you please respond as soon as you can. Thank you, Judy

      • tyrocdoug2 says:

        This question has come up before from another carpet installer. And I told him: use common sense on the tension. If the tack strip is adhered with an adhesive glue (PL Premium as recommended or a self adhesive tack strip) in addition to the normal nails in the tack strip to the Tyroc there should be no problem just as a normal lay down. However if you are going apply more tension for some reason then see below. Your issue here is the Tyroc has already been laid down and I don’t know that there is enough gap to allow the tack strip to be fastened directly to the concrete. Please if you have any questions give me a call. Carpet has been installed over Tyroc in 1,000’s of projects with no concerns.

        My VP of Operations and Product Development responded this way.

        “If they are going to power stretch the carpet, they should leave a gap around the outside of the room that will allow the tack strip to be fastened directly to the concrete.
        This would place all of the tension on the tack strip and avoid any buckling of the Tyroc.”

  70. Martin says:

    Can I nail a new hardwood floor directly on top of Tyroc? The Tyroc would be installed on top of plywood.

    • tyrocdoug2 says:

      Yes Martin you can nail hardwood flooring directly over Tyroc installed over plywood. Just be sure you are using enough length in your staples/nails to penetrate through the Tyroc (1/2″) to secure into your plywood.

      Question…are you installing this floor in a basement or above ground? Just curious.

  71. Judy says:

    If this is installed as a floating system, how do we power stretch carpet over it?

  72. Ty says:

    Hi Doug,

    2 questions, I tried to find it above, but if I want to install a floating engineered hardwood on top of tyroc, do I need to put anything in between the two?

    And secondly, I live in Etobicoke (Western Toronto) and wanted to see if any of the Rona’s in the area carried your product.


    • tyrocdoug2 says:

      Hello Ty,
      There is no need to put any additional barriers between your engineered hardwood and Tyroc as the Tyroc is your moisture barrier. Install your engineered hardwood according to the manufactures recommendations.

      You can call the Rona store nearest you to see if they have Tyroc in stock. If not they can order it. You may want to check with Home Hardware as well.

  73. Tim Armentrout says:

    I am in Fredericksburg VA (22401) and would like to know where the nearest dealer to purchase TyRoc is located to me. Also, what’s the approximate per square foot price? Thanks in advance,

  74. Bridget says:

    Hello Doug,

    I’m interested in using Tyroc in a basement apartment, with a tile finish layer. I read the TCNA test results and was concerned that tiles broke under a 300# wheel load. Would a a Tyroc/tile floor support a couch with 3 X 200# guys sitting on it without cracking the tile? What about supporting a refrigerator?


    • tyrocdoug2 says:

      Yes Tyroc Subflooring will perform with a tile installation under these circumstances. Tyroc Subflooring will also protect your tile installation from any moisture issues that is the #1 cause for tile failure over any flooring substrate and particularly over concrete.

      The force exerted during the tile test is very high because of the small surface area of the wheel. A 300 lb weight being supported by approx .25 square inches exerts a force of 1200 psi. This compared to 3 guys at 300lbs each sitting on a couch with 4 feet, each foot having at least 1.5 square inches of area. The total force is only 900 lbs spread over 6 square inches or 150 psi. Almost 1/10th of the force exerted during the test. In order to achieve the same force there would need to be 24 300lb guys on the couch. A refrigerator is even less force.

      Hope this helps in your choices of selecting a subfloor for your basement project.

  75. Marc Denomme says:

    I am considering installing old growth hardwood on top of tyroc in my basement. The hardwood flooring consists of a 3mm layer of the recovered hardwood (recovered from Georgian Bay, as old as 500 years,300+in age, over 100 years submerged) glued to 9 layers of plywood style totalling 19mm. The look is unbelievable and is constructed like todays engineered products. Can I glue it directly to the tyroc, and what type of glue is recommended?

    • tyrocdoug2 says:

      Tyroc Subflooring is ideal for engineered hardwoods as it will provide a smooth level surface and a moisture barrier for your finished floor. Yes you can glue it directly to Tyroc. Please follow the manufacturers recommendations in terms of the glue required for their product installation.

  76. Lori says:

    Does Tyroc have an odor? I’m sensitive to the smell of tires. I’d love to use this product in our basement.

  77. Mary Lou says:

    In Texas we don’t have basements but we are planning on building slab on grade. I haven’t seen any discussion for this application. We would like wood floors and this seems like it would work well in this situation

    • tyrocdoug2 says:

      Mary Lou,
      Tyroc Subflooring was initially designed to solve flooring problems in wet basements (moisture issues, mold and mildew issues etc.) Once entering the market Tyroc has been found to protect any finished floor covering over all concrete floors, including slab on grade and multi-level concrete substrate floors (poured concrete). Tyroc serves as a moisture barrier over any concrete substrate. This is the most common issue with finished flooring over a concrete substrate as concrete is porous. Concrete sweats with changes in temperature and humidity and allows moisture to transfer. Tyroc protects your wood floors from any moisture transfer from the concrete up and provides a stable surface from any potential shift in the concrete slab.

  78. Jason says:

    I considering using Tyroc when I finish my basement this winter. I’ve confirmed that the Rona near me (on Rymal Road in Hamilton, ON) carries the product and has it in stock. What I’m wondering is how you secure the walls to floor? Do I still use Tapcons to drill through the 2×4, Tyroc and into the concrete floor?

  79. moored says:

    I want to install Tyroc in my basement which has Lino tiles over cement. I may be installing electric radiant heating. Can I install the Tyroc on the tiles and do the heating cables go on top of the Tyroc? Also if there were no heating cables can vinyl tiles be applied directly to the Tyroc?

      Yes Tyroc can be installed directly over the linoleum tiles that have been installed over cement. And yes you can install your radiant heating system over Tyroc (not under it). And vinyl tiles can be installed over Tyroc according to the vinyl manufacturers recommendations. In this type of assembly Tyroc is the subflooring and should not be considered as a replacement or alternative to the recommended underlayment for the vinyl that is to be installed. Tyroc will naturally warm your floor by about 7-10 degrees (F). So determine if you are using radiant heat to heat your space or just your floor. You will also find that Tyroc will reduce the amount of humidity you may have in your basement currently and therefore provide a dryer, warmer space.

    We are installing Tyroc subfloor over the concrete basement floor. We want to use a floating, laminate flooring for the finished floor … I assume we still need an underlayment for the laminate … hubby disagrees. What is your suggestion?

    • tyrocdoug2 says:

      Jan, Tyroc provides the protection as a moisture barrier for the laminate flooring. However, most laminate flooring manufacturers have a specific requirement in their warranty about using an underlayment so as not void their warranty. You can use the most inexpensive type of underlayment to satisfy the manufacturers warranty.

    Is it possible to install tyroc on top of a rigid foam insulation product to provide a much higher r-value for a basement floor?


    • tyrocdoug2 says:

      Tyroc Subflooring is thermal barrier as well as a moisture barrier. Without specifically testing this type of assembly it would be difficult to say what you may gain in R Value. Tyroc on its own has over a 3.2 R Value and is going to reduce cold from transferring from the slab up and will also reduce heat loss from the top down. We recommend that Tyroc be used as the subfloor – underlayment over the concrete and then what ever you choose to add to it is added on top. That way the Tyroc will protect your finished flooring assembly from any moisture issues and movement (expansion/contraction) in the substrate (i.e. concrete slab). There is a point of diminishing returns (overkill) on adding more materials to a project. You will also want to consider what type of finished floor you are installing over your subfloor assembly. Will the rigid foam support your finished floor? Check the manufacturers specifications. You can apply any type of finished flooring over Tyroc – tile, laminate, engineered or natural hardwood, vinyl or carpet.

    I was thinking of putting tyroc down as a subfloor in our basement. the basement floor gets very cold in the winter. What is the insulating r-value for tyroc. I can’t seem to find this info anywhere.

    • tyrocdoug2 says:

      Tyroc is a thermal barrier and will help insulate your finished floor. Tyroc is currently re-testing its R-value, however we do know Tyroc will raise your floor temperature by as much as 7 – 8 degrees (F) or more. It will also help with your energy bills if you are running a humidifier in addition to heating/cooling.

  87. Eleanor says:

    I was thinking of putting tyroc down as a subfloor in our basement. the basement floor gets very cold in the winter. What is the insulating r-value for tyroc. I can’t seem to find this info anywhere. Will tyroc help much?

    Also, what kind of smell does the rubber on the bottom layer have and does thsat off gas?


    • tyrocdoug2 says:

      Tyroc is a thermal barrier and will help insulate your finished floor. Tyroc is currently re-testing its R-value, however we do know Tyroc will raise your floor temperature by as much as 7 – 8 degrees (F) or more. It will also help with your energy bills if you are running a humidifier in addition to heating/cooling. There may be a light odor from the rubber when first laid dependent on the manufacture and delivery dates, however once installed and properly ventilated Tyroc has no off gas or persistent odor. Just like any new flooring it has a “new floor” smell for a couple of days. Let me know if you have any futher questions.

  89. May Knox says:

    I live in Halifax, Nova Scotia. I have contacted the local Rona and Home Hardware stores but they have not heard of your Tyroc product. I want to use Tyroc for my basement subfloor. How fast can you folks get a shipment to Halifax? (I need 270 square feet). Thanks.

    • tyrocdoug2 says:

      May currently we do not have a dealer in Halifax. We will connect offline to determine if we can help you direct.
      Tyroc is distributed on the East Coast from Maine to Virginia and we are establishing new dealers every day.
      Thank you for your interest in Tyroc.

      Thanks, Doug

  91. John says:

    Your product information indicates that ceramic tile can be installed on top of Tyroc. When I checked with my tile installer, he said he would recommend against this because Tyroc is a floating subfloor. He said that if there is any vertical movement, the tiles or grout would crack. Can you comment on this?

  92. Stephen says:

    If you are starting from a completely unfinished basement, what is the recommended installation order: Tyroc all the way to the concrete walls then build walls *on top* of Tyrox OR build walls on concrete floor then install Tyroc?


    • tyrocdoug2 says:

      Stephen you can build

        non-load bearing

      framing walls over Tyroc. I would recommend triming the ship-lap edges so you have a blunt edge against the outer wall. Tyroc will not expand or contract from temperature differences or moisture (it is impervious to moisture and water). However you want to keep in mind that you will be building up the floor by 1/2″ in height and will need to allow for that in your framing.

  93. Don Ferguson says:

    Is Tyroc subflooring available in Hamilton Area? I can not location on Rona or Home Hardware web site. Is it special order? How long would a special order take?

    Thanks, regards
