Deckdrain is a high performance geocomposite drainage layer that replaces traditional stone filter layers with distinct benefits. Deckdrain structural drainage systems are specifically designed to provide high flow capacity and added protection to waterproofing membranes.

Deckdrain consists of a high strength flexible polyethylene cuspated core with a non woven geotextile filter bonded onto either on or both sides. The product is practically impermeable on one side. It is used as an engineered drainage layer behind retaining structures, on roof decks and in subsurface works. Deckdrain is also used as a void former to create drainage paths within concrete structures such as tunnel linings or under concrete paving.
