Description

A cavity drainage geo-composite layer comprising a high-performance single cuspated HDPE (high density polyethylene) core with a geotextile filter thermally bonded to one side. The textile filter has a flap that extends beyond the core on one edge. The product is effectively impermeable one side and is used as an engineered drainage layer in waterproofing applications.

The geotextile filters a wide range of materials whilst allowing the free ingress of fluids into the core of the geo-composite before draining to a discharge point. The HDPE core provides a free flowing drainage void within the structure. The studs are designed to support the geotextile which is bonded to the core to ensure that it doesn't deform into the drainage passage under the pressure of the fill material. The core design allows flow in all directions.

Features and benefits:

  • Horizontal or vertical drainage applications.
  • Thinner drainage layers when compared to traditional solutions.
  • Rapid installation.
  • Enhances the performance of structural waterproofing by providing an additional barrier that prevents most of the water reaching the structure.
  • High puncture resistance.

Applications:

  • Relieve external water pressure from buried structures.
  • Drainage on positive side of retaining walls.
  • Block paving drainage.
  • Waterproofing to structural roof decks.

Can be used in conjunction with:

  • SovDrain Membrane Plug - for fixing.
  • SovDrain Corner Strip - for floor/ wall juncture sealing.
  • SovDrain Aquaduct - for drainage facility.
