WM40 (Waterproofing Membrane 40 mil) is specifically designed and engineered for use with Insulated Concrete Forms (ICF) technology. It is also an excellent choice for waterproofing poured concrete foundation walls, Concrete Masonry Unit (CMU) walls, and related applications where waterproofing is critical or hydrostatic pressure is present. 

WM40 is a 40 mil thick, self-adhering, peel and stick sheet waterproofing membrane. It consists of a strong pliable high density polyethylene (HDPE) facing bonded to a rubberized asphalt waterproofing compound, a technology that has been proven effective over many years of use. WM40 is available in easy to handle and install 36” wide by 66.7’ long rolls (200 sf / roll) with a disposable treated release liner.
