TriDent™ DD is a high-performance drainage mat engineered to relieve hydrostatic pressure by creating an exit channel for liquid water. Utilizing a two-layer system, TriDent™ DD provides the user with a high-strength product used for applications in both below-grade foundations and foundation walls. The first layer is constructed of a high strength, moisture impermeable, cuspated (dimpled) polystyrene sheet designed to provide superior compressive strength. Adhered to the high strength, cuspated polymer base is a nonwoven, polypropylene filter fabric. The filter fabric works in conjunction with the HIPS sheet to promote a high-water flow while preventing silt, dirt, and concrete from penetrating the drainage channel.
