WPA Drainage Cell

WPA Drainage Cell is a two-core drainage sheet consisting of a non-woven geotextile filter layer thermally welded to a water impermeable, recycled HDPE (High Density Polyethylene) drainage membrane. WPA Drainage Cell provides outstanding drainage and protection to the outside face of basement walls, preventing the build-up of water pressure and protecting the structure from aggressive water, chemicals and toxins.

​

• Recycled and recyclable HDPE core.

• Prevents water pressure from bearing against the structure.

• Resistant to all chemicals normally found in the ground.

• Withstands stresses and movement acting as a slip membrane as the backfill settles.

• Extremely strong material, minimising the risk of damage.

• Very high compressive strength.

• ECO manufactured with no production waste.

• Suspended soil particles (fines) are filtered out by the geotextile layer.

• Quick and easy to install with a range of ancillary fixing and installation products.

​

Recommended uses:

• As the drainage layer of an externally applied waterproofing system when used in conjunction with sheet applied or liquid applied external tanking membrane to BS8102:2009.

• Protection of the structure from aggressive chemicals in the ground water.

• To prevent the build-up of ground water to retaining walls.
