Re: Subfloor Over Concrete For Hardwood
I'm curious why they are "insisting" on this?

Re: Subfloor Over Concrete For Hardwood
I wouldn't put a nail down solid wood in a basement!
You need to think about a floating engineered, seriously. As the replacement will be on your wallet.

Re: Subfloor Over Concrete For Hardwood
HD stocks a product that is OSB over a plastic waffled base, comes in a 2'x2' T&G. One Tapcon screw in the center of each panel will suffice in most cases. It is designed to go over concrete, the waffle design allows air movement underneath. I know of one person who put it down under carpet in a basement with good results. I'm considering it over a slab to do a laminate floor in my own home.

Re: Subfloor Over Concrete For HardwoodQuote:
How old is the concrete? Sump pumps--do they run often? Are dehumidifiers in use (preferably tied to the HVAC system)? What's the RH in the basement on a dry day vs. a rainy one? Even if it's fairly dry--I'd still recommend an engineered floor vs. solid. And if it's marginal hardwood may just be a bad idea.

Re: Subfloor Over Concrete For Hardwood
Maybe flagstone. That should fit with woodsy interior and eliminate moisture concerns.

Re: Subfloor Over Concrete For HardwoodQuote:
This went down first and then screwed 3/4 T&G plywood with tap-cons every 2 feet and then laid 3/4" T&G Maple with 1 1/2" nails with an air assisted flooring nailer. I researched this and posted questions on some other forums I visit. This seemed to be the best solution, and now after installing the DeltaFL I believe it is a very good product. Good Luck Dave |

Re: Subfloor Over Concrete For Hardwood
Why not a floating floor, similar to a jazzercize floor. 3/4" ply on heavy rubber pads that float on the concrete floor with a standard 3/4" maple strip floor on top.

Re: Subfloor Over Concrete For Hardwood
I agree with ChrWright about concerns AND here is one you should be concerned with............what installation system will the manufacturer warranty? If you go outside the published system criteria for this installation you will not get anywhere with the manufacturer.
For this install I would be very concerned about my risk management. |

Re: Subfloor Over Concrete For Hardwood
I would use the ashphalt cut moisture barrier first then , install 1x3 sleepers 11 on center for a basement nail down job. Go to the NOFMA website and read about the cut-back moisture barrier and sleeper system. It has been effective for over many years

Re: Subfloor Over Concrete For Hardwood
you could try using these products from Sika,
Sika Primer MB Epoxy-Based Moisture Barrier, to deal with any possible damp issues, then use Sikabond-T54 Solvent-free Polyurethane Adhesive or Sika Bond- T55 low VOC Polyurethane Adhesive, the adhesive is flexible so it can cope with expansion & contraction, this allows engineered & solid wood to be used above & below grade, they put a warrenty with their products. Sika have had these products used for over 1 million sq yds, they are also widely used throughout europe, Tommy Hilfiger have this as their approved installation method in all there stores in canada, Sika also do a stick down method that also uses a sound proofing underpad (Sika Acoubond) for use with concrete floors in condo's all these methods are designed to do away with the old methods of laying a ply subfloor first and nailing down the wood floor, they also solve the problem of reducing the height of the room. Not able to put their link up so just google sika, or sika.ca, or Sikacanada.com they are a world wide company so you should find them ok

Re: Subfloor Over Concrete For Hardwood
Ian, in a basement environment, it is not only the substrate moisture but the under ground humidity, that says solid is a really bad idea.
Sure you speed down that road everyday, but tomorrow, Johnny Law is there and gives you a ticket.

Re: Subfloor Over Concrete For Hardwood
Working on the basis that if they are looking to put solid wood into the basement, the area will be fully developed and will get regular use/ poss even a Bi level, with this in mind the humidity in the area should be controlled much like the rest of the home and should not cause too much of a problem.
I have found that it is only in the USA & Canada that people shy away from solid wood below grade, Europe and other parts of the world do not seem to have a problem as long as they use the correct materials and preparation, of course as with most flooring products (not just wood) the manufacture states that the area should maintain temp & humidity between normal levels, Have a look at this link to see just how far solid wood has come, 18 mil solid oak laid as floating floor with a easy click system. W w w. hardwood-floors.uk.Com/solid hardwood Sorry but not able to display full link

Re: Subfloor Over Concrete For Hardwood
I am a little surprised to hear that, the adhesive is meant to be laid into wet (it has a short open time) and when set it should be semi flexible not ridged, what did Sika say about it when you told them ?
