Application

Extensive green roof drainage layer.

Description

Roofdrain 40mm geocomposite drainage board and water attenuation layer comprising a perforated cuspated HDPE (High Density Polyethylene) core with selected geotextiles thermally bonded on each side.


It is primarily intended for use under thin soil layers where the plant roots can reach down to the water in the core reservoirs. The core is perforated to allow excess rainwater to flow into the underside and away to the rainwater outlets. The upper textile is optimised for drainage performance and the lower textile protects the waterproofing system.


Its major application is in extensive roof garden drainage, providing a lightweight drainage layer and water reservoir to sustain plant growth. Roofdrain makes extensive use of recycled polymers in its manufacture.
