    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

    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 8102:2009.
    • Protection of the structure from aggressive chemicals in the ground water.
    • To prevent the build up of ground water to retaining walls.
