TerraDrain® C-100 Series

TerraDrain® C-100 Series prefabricated chimney drains are constructed by fully wrapping a high strength, highflow capacity, formed polystyrene perforated core with a nonwoven filter fabric. The filter fabric is bonded to the core tosoil prevent soil intrusion into the flow channels while allowing water to freely enter the drain core from both sides.

TerraDrain® C-100 Series chimney drains are available in 12”, 16” and 24” widths and provide a time saving, effective drainage solution for reducing hydrostatic pressure against retaining walls where full wall coverage is not required or is not feasible. TerraDrain® C-100 Series products are available with filter fabrics meeting AASHTO M 288-06 specifications.
