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.
Provides a clear and clean drainage path for surface water to roof drainage outlets.
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, particularly where:
