Deckdrain

Deckdrain is a geocomposite drainage layer comprising a high performance single cuspated HDPE (High Density Polyethylene) drainage core with a nonwoven geotextile filter thermally bonded to the one side. The geotextile filter has a flap that extends beyond the core on one edge and the product is practically impermeable on one side.

It is used as an engineered drainage layer in structural applications, its major areas of use being behind retaining structures, basement walls, on roof decks/gardens and in subsurface works.
