      • The BEST way to control moisture and give your floor a softer feel!
      • July 17, 2015
      • Recommended Product

      I bumped into this product searching the Internet for a way to waterproof my basement floor. I emailed several questions directly to the manufacturer and they responded immediately with details on how to handle each situation. DMX 1 Step is easy to install and as I covered more of the concrete floor I started to notice that musty basement smell could not be detected in the areas I completed. The hardest part for me was drilling into the concrete floor to use the TAPCON screws. Buy a higher quality hammer drill and lots of drill bits. I installed 5/4 x 4 sleepers and then 3/4" OSB glued and screwed over top. The sleepers are installed 24" on center. The floor has the same kind of flex as the main level of the house. My wife loves the way it feels when she walks on the basement floor. The moisture control is allowing us to install hardwood floor in the basement. That is typically a no-no. I'm confident the DMX 1 Step is going to be the key to my finished basement not looking or feeling like a finished basement. It's a great product!
