Double cuspated, deck and flat roof drainage membrane, that incorporates a non-woven geotextile filter layer, bonded to a water impermeable HDPE (High Density Polyethylene) core. The unique double cuspated design provides two layers of drainage; allowing for primary drainage through the geotextile filter, as well as secondary drainage between the underside of 207 DeckDrain and the primary waterproofing layer.
Provides a clear and clean drainage path for surface water to roof drainage outlets.
Unique double cuspated (drainage studs to the upper and lower surfaces) design provides a clear and clean drainage path above the deck primary waterproofing membrane, to ensure that water cannot be trapped above the deck membrane, as can be the case with single cuspated deck drainage membranes.
Very high compressive strength.
Suspended soil particles (fines) are filtered out by the geotextile layer.
Quick and easy to install
As the drainage layer above a deck, balcony or flat roof waterproofing membrane such as Newton Acriflex Winter, particularly where:
Block paviours or flooring slabs are bedded on sand as the surface finish.
Soil filled planters are included to the deck or flat roof.
An Intensive Green Roof is planted to the deck or flat roof.
Also suitable for use as a vertical drainage layer when used as part of a professionally designed and installed externally applied basement waterproofing system.
