Blackdown are horticultural experts and offer a single source solution – growing, supplying, installing and maintaining green roofs that comprise of plants ideally suited to the UK’s climate. These systems are fully compatible with Alumasc’s root-resistant waterproofing membranes.
40+FS consists of a perforated cuspated HDPE (High Density Polythylene) core with selected geotextile thermally bonded on the upper flat 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 the excess rainwater to flow into the underside and away through the 40+FS to the outlets. The textile is optimised for drainage performance. It’s major application is in semi-intensive or intensive roof garden drainage where 40+FS provides a lightweight drainage layer and water reservoir to sustain plant growth.
40+FS makes extensive use of recycled polymers in its construction.
