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 nonwoven geotextile filter bonded onto one side. The product is practically impermeable on one side. It is used as an engineered drainage layer behind retaining structures, on roof decks, green roofs, planter boxes 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.

Deckdrain 600S/NW8 

Our Deckdrain 600 is wafer-thin at only 6mm thick. This 2-in-1 product combines the filter capabilities of a nonwoven geotextile and the vital structured drainage core of the HDPE cuspated sheet. The filter geotextile allows free drainage into the core whilst preventing soil migration into the drainage path. The geotextile is manufactured from up to 95% recycled material making it an environmentally sound choice. The product comes in rolls of 1.1m wide x 50m long, making them easy to handle and install on site.
