Terradrain

Terradrain prefabricated drainage systems consist of a polymer core with a geotextile laminated on one side. The geotextile allows water or gases to pass into the drainage core while restricting the movement of soil particles, which might clog the core. The core provides a void to allow the liquid or gas to flow to designated outlets.

terrafix offers the following Terradrain products:

Terradrain 200

Terradrain 200 is a geocomposite drain designed for foundation wall drainage where the drainage panel is applied against rigid surfaces such as lagging, caisson walls or excavated rock surface. It provides effective relief of hydrostatic pressures through full wall coverage or frequent vertical strips. Terradrain 200 can also be applied against a finished foundation wall to a limited depth.

Terradrain 600

Terradrain 600 was designed for vertical and horizontal applications such as foundation walls, bridge abutments, retaining walls, under floor slabs, roof gardens and patios. Terradrain 600 has a geotextile laminated on one side of the plastic core to allow water entry while filtering the soil. The other side of the core is flat to fit against the wall.

Terradrain 620

Terradrain 620 has a thin, high-strength plastic sheet added to the flat side of the core to provide extra protection when applied over softer waterproofing materials. The plastic film prevents intrusion of the soft membrane into the back side of the core dimples.

Terradrain 900

Terradrain 900 is a lightweight drainage system designed for horizontal drainage of parking decks, plaza decks, balconies and under slab applications. In comparison to conventional aggregate drains, roof loading is dramatically reduced. When used beneath planted areas the thin profile allows maximum topsoil depth for proper root growth.
