    I used this as underlayment in my basement. Placed it directly against concrete floor, then installed 23/32 T&G OSB on top, secured with Tapcon screws, gives a nice level surface to install floating floor. I wouldnt install flooring directly on top of it without placing a layer of OSB anchored to the concrete first, or you’ll end up with a very noisy floor. The air gap keeps moisture away, as well as provide some thermal insulation. Floor feels warmer and solid! As some of the online review comments say, it does smell a little but not bad really, and after it is inatalled, the smell is gone. At $0.36 per sq.ft, its almost half price compared to similar products in other brands. Its easy to cut with a utility knife, but i give it 4/5 stars since it can be a litte tricky to line up and get the tape to stick when overlaping two layers. I used the silver underlayment tape and it doesnt want to stick well… it may have worked better with some higher quality and stickier tape.

    A few minor cuts in the most outer aspect, due to being moved around during shipping. But overall a sturdy, reliable product.

    -Secured with Tapcon screws

    I used this as underlayment in my crawl space, with a vapor barrier over top.
    Gives you a relatively comfortable surface to crawl on and provides a layer of protection to the vapor barrier from rocks and other debris on the dirt floor. Cuts easily with a utility knife.
    Have seen this same product marketed specifically for crawlspaces as “dimpled underlayment” on specialty crawlspace supply websites for much more. Purchasing through was less per square foot.
