APP (Atactic Polypropylene) is a waterproofing membrane manufactured from modified bitumen with the addition of plastomers. The membranes are reinforced by either fiberglass, polyester or composite. The combination of all elements result in a product that prevents water from penetrating into structures therefore eliminating structural damage from moisture and water.
