Roof Garden Deckdrain
Deckdrain forms a lightweight high performance drainage layer with integrated filter geotextile that eliminates clogging within the drainage structure that provides a continuous drainage layer across the structure. It has been specifically developed to provide high flow capacity and added protection to waterproofing for intensive green roofs and roof gardens. gt Deckdrain is durable and sufficiently robust to resist the mechanical stresses imposed during installation and then on throughout its design life.
