GREENFOND 20 Garden R1000 retention and drainage layer made of hardened polyethylene (HDPE) with a 20 mm high profile.


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.


Roll dimensions:

- 2 x 20 m
