ASSEMBLY
The DRENAXX 20 dimpled membrane in the construction of green roofs is laid on a layer of absorbent-protective non-woven fabric. The cusps should face down (the membrane must not be laid with the notches down) and an overlap of two rows of cusps should be created.
To prevent the finer parts of the substrate from washing away, a filter layer of geotextile should be applied to the membrane. Then the substrate is placed on this layer with a layer of vegetation.
