Newton 408 Deck Drain (M33)
Application

As the drainage layer above a deck, balcony or flat roof waterproofing membrane such as Newton 103-S or Newton 107F, 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.

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.

Description

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.

Features and 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
  • Suspended soil particles (fines) are filtered out by the geotextile layer.
  • Quick and easy to install.
