GREENFOND 20 Garden Premium retention and drainage layer (HDPE) with high water accumulation and load resistance with a 20 mm high profile.

It is used in system solutions for intensive and extensive green roofs.

The innovative shape of the profiles and a properly selected mixture of hardened polyethylene HDPE have a significant impact on the mechanical and physical properties of the product, thanks to which we obtain above-average retention parameters in its class.


GREENFOND Garden 20 Premium is also an innovative design of the entire module. Thanks to a special embossing on its edges, we can connect them to each other, which, in contrast to the currently used solutions, laid using the so-called "Joint" plate next to the plate, we get a stable structure of the entire drainage layer with a simultaneous easy and quick installation method for the contractor.


GREENFOND 20 Garden Premium has an additional special embossing on the upper surface of the profile, which slightly unseals the direct contact with the GREENFOND TEX 100 drainage fleece, which allows for free air flow between individual sections, and in cases of heavy rainfall also for effective drainage of excess water.


Extreme accumulation of water - approx. 12 liters / m2

Above average compressive strength - 400 kN / m2


Board dimensions:

- 2.1 x 1.1 m
