TerraDrain® Strip 600 Series

TerraDrain® Strip 600 Series prefabricated soil drains are constructed by fully wrapping a perforated, high flow capacity polystyrene core with a nonwoven filter fabric. The filter fabric is bonded to the core and prevents soil intrusion into the flow channels while allowing water to freely enter the drain core from all sides.

TerraDrain® Strip 600 Series products offer a cost effective, sustainable, performance driven alternative to costly perforated pipe and stone systems. TerraDrain® Strip 600 Series products are available with filter fabrics meeting ASSHTO M 288-06 Class 1, 2 or 3 specifications.
