12 mm thick geo-composite studded drainage membrane.
Can be used in conjunction with:
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.
