RamDrain DD 050 HS is a two-part prefabricated geocomposite drain consisting of a formed polystyrene core that is covered on one side with woven monofilament filter fabric. This fabric allows water to pass into the drain core while restricting the movement of soil particles which might clog the core, allowing the water to flow to designated drainage exits.
RamDrain DD 050 HS with ½" height can move more drainage water per foot width than a layer of stone which is 1' wide and 180" high.
RamDrain DD 050 HS is designed for horizontal applications.
