Two-core drainage sheet consisting of a non-woven geotextile filter layer thermally welded to a water impermeable HDPE (High Density Polyethylene) drainage membrane.
 
Key Benefits
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.
Allows for backfilling with excavated earth.
Extremely strong material, minimising the risk of damage when backfilling even when no protection board is used.
Very high compressive strength.
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.
 
Typical Applications
As the drainage layer of an externally applied waterproofing system when used in conjunction with sheet applied or liquid applied external tanking membrane to BS 8102:2022.
Protection of the structure from aggressive chemicals in the ground water.
To prevent the build up of ground water to retaining walls.
