Drainage membrane for decks and flat roofs.
As the drainage layer above a deck, balcony or flat roof waterproofing membrane such as Newton 103-S or Newton 107F, particularly where:
Also suitable for use as a vertical drainage layer when used as part of a professionally designed and installed externally applied basement waterproofing system.
When used conventionally below block paving or slabs bedded on sand, Newton 408 DeckDrain requires at least one drainage outlet per 10 linear metres of membrane. Consult manufacturer for further details.
Newton 408 DeckDrain is a double cuspated, deck and flat roof drainage membrane, which incorporates a polypropylene geotextile filter layer, bonded to a water impermeable high-density polyethylene (HDPE) core. The 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 408 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.
