Dimpled Composite Drain

RamDrain Dimple Drain (DD) 025 HS is a high-performance drainage sheet engineered to relieve hydrostatic pressure by creating a channel for liquid water.

RamDrain DD 025 HS is a two-layer extremely high compression strength system. The first layer is constructed of high strength, cuspate (dimpled) polymeric sheet designed to provide superior compressive strength. Adhered to the high strength, cuspated polymer base is a nonwoven filter fabric. The non-woven spun-bonded filter fabric is designed to promote high water flow while not allowing dirt and silt to penetrate the drainage channel.
