High-Strength, High-Flow, Prefabricated Drainage Composite with Protective Film
Mapedrain 25 is a high-strength, three-dimensional drainage composite. It consists of a nonwoven filter fabric bonded to individual dimples of the molded polypropylene core, minimizing fabric intrusion into the drainage channels caused by overburden pressure. The filter fabric allows water to pass freely into the drainage core, which provides hydrostatic relief while preventing the passage of soil or sand particles which might clog the core. Mapedrain 25 also has a polymeric protective film on the back side to provide additional protection to waterproofing membranes.
