Terradrain 101



TerraDrain 101 is a two-part prefabricated geocomposite drain, consisting of a formed polystyrene core covered on one side with a nonwoven needle-punched polypropylene filter fabric. The fabric allows water to pass into the drain core while restricting the movement of soil particles that might clog the core. The core allows the water to flow to designated drainage exits. TerraDrain 101 is nonbiodegradable and resistant to most soil chemicals, acids, and alkalies with a pH range of 3 to 12.

TerraDrain 101 is manufactured to meet or exceed the following requirements:
