PercoDrain 15-B is a three-part prefabricated geocomposite drain consisting of a formed polystyrene core covered on one side with polypropylene filter fabric. The fabric allows water to pass into the drain core while restricting the movement of soil particles which might clog the core. The core allows the water to flow to designated drainage exits. PercoDrain 15-B is designed for vertical applications. PercoDrain 15-B has a built-in Polymeric film protection layer for use as required by manufacture of some waterproofing materials in order to be a compatible protection layer. PercoDrain 15-B with ½" height can move more drainage water per foot width than a layer of stone which is 1' wide and 180" high.
