Newton 407 DeckDrain is a double cuspated, deck and flat roof drainage membrane, that incorporates a non-wovengeotextile 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 407 DeckDrain and the primary waterproofing layer.
The lower drainage layer eliminates the risk of trapped water, a problem associated with conventional single cuspated deck drainage membranes.
