The Dimpled Drainage Sheet is a perforated dimple sheeting with high drainage capacity for horizontal use on retaining wall, roof slabs, under floor slabs, roof landscaping, parking decks and mostly used for basement walls and tunnel drainage.
The dimples in the membrane create a drainage space that allows the wall to breathe. It prevents 100% of the headwater pressure off the face of the wall due to hydrostatic pressure. The space allows moisture to condensate outward onto the membrane. The Dimpled Drainage Sheet protects the structural parts of buildings which could come into contact with soil and earth.
