GREENFOND 20 Garden DUO R1000 retention and drainage layer made of high-density HDPE polyethylene, integrated with durable filter geotextile.
Thanks to the appropriately selected shape and 20 mm high embossing, this product is characterized by an optimal water accumulation capacity, which allows it to be successfully used on extensive green roofs.
However, thanks to a properly made perforation, excess rainwater can be freely directed to the roof drain.
All used product components are fully recyclable.
The product has an excess of non-woven fabric over its width, which makes it easier to stack individual products among themselves.
The use of a substrate directly laid on the filter fleece is fully possible.
