Terradrain - Model 620 -Geodrain

Terradrain® 620 is installed much the same way as Terradrain® 200 and 600. If Terradrain® 620 is being applied over a soft waterproofing membrane it is important to hold it in place using a method or device that will not puncture the membrane.

Terradrain prefabricated drainage systems consists 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. Terradrain provides a cost-effective alternative to aggregate drains and a solution to many drainage and vapour problems.
