Platon Waterproof Foundation Membrane Wrap, 10 ft x 65.6 ft

Platon® is a rugged, dimpled, High-Density Polyethylene (HDPE) membrane that keeps wet soil away from the foundation wall. The air gap drainage path carries any moisture that may find its way past the membrane to the foundation drain. Platon is commonly used to waterproof block walls, poured concrete walls, permanent wood, existing foundations, and Insulated Concrete Forms (ICF).
