TerraDrain™ 7DW Fildrain Gas Vent and Stripdrain
TerraDrain™ 7DW
gas vent & strip drain is a high performance, high compressive strength, high flow drainage composite consisting of a three dimensional, high impact double cuspated / dimpled HDPE core combined with a non-woven filter fabric wrap..
The filter fabric is bonded to the individual dimples of the core to minimise fabric intrusion into the flow channels caused by soil backfill pressure.
The fabric prevents small soil particles from clogging the drainage channels but allows water / moisture to pass freely.
Applications
• Geomembrane / liner subgrade gas vent
• Sports field drainage
• Foundation / secant pile drainage
• Retaining drainage
• Cut-off / interceptor drains
