External Drainage Membranes:

An External Drainage Membrane is a two-core drainage sheet consisting of a non-woven geotextile filter layer thermally welded to a water impermeable HDPE (High Density Polyethylene) drainage membrane.

External Drainage Membranes provide outstanding drainage and protection to the outside face of basement walls to sloping sites, preventing the build-up of water pressure and protecting the structure from aggressive water, chemicals and toxins.

Benefits of an External Drainage Membrane:

• 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.
