A two-part prefabricated geocomposite drain: a formed polystyrene core covered on one side with woven mono-filament filter fabric. Designed for horizontal applications.
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.
vs. stoneWith a ½″ height, PercoDrain 20 can move more drainage water per foot width than a layer of stone 1′ wide and 180″ high.
