Drainage Membrane for Decks and Flat Roofs. Newton NewSeal 408 DeckDrain is a double cuspated, deck and flat roof drainage membrane, that incorporates a polypropylene geotextile filter layer, bonded to a water impermeable HDPE (High Density Polyethylene) core. The double cuspated design provides two layers of drainage.

Key Benefits: 

  • Provides a clear and clean drainage path for surface water to roof drainage outlets.
  • Double cuspated (drainage studs to the upper and lower surfaces) design provides a clear and clean drainage path above the deck waterproofing membrane, to ensure that water cannot be trapped above the deck membrane, as can be the case with single cuspated deck drainage membranes. S
  • uspended soil particles (fines) are filtered out by the geotextile layer.
  • Quick and easy to install.

Typical Applications: 

  • As the drainage layer above a deck, balcony or flat roof waterproofing membrane, particularly where:
  • Block paving 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.

Suitable Substrate:

  • Directly above primary deck or roof waterproofing membrane.
