Membranes & Underlayments
Your subfloor helps to determine the proper underlayment required for your project. Used as a moisture barrier, preparing your subfloor correctly for the flooring you will install is primordial. Basement waterproofing is especially important and a good underlayment will help you achieve the perfect result.
