PM P-STANDARD GS-GEOTEX
PM P-STANDARD GS-GEOTEX is a water-storing drainage membrane and is the ideal solution for extensive green roofs.
PM P-STANDARD GS-GEOTEX is a water-storing drainage membrane and is regarded as an ideal solution for extensive roof greening. Compared to normal dimpled membranes, PM P-STANDARD GS-GEOTEX offers a high drainage and water storage capacity and assumes the function of a protective, filter, seepage and water storage layer in green roofs.
The 8 mm dimples have a water storage capacity of approx. 3 l/m². The pressure resistance of approx. 200 kN/m² offers a high level of security, corresponding to a compressive strength of approx. 20 tonnes per m². The 8 mm dimpled membrane also offers a high drainage capacity.
The plant substrate can be applied directly as the geotextile is already integrated. This saves an additional work step. Thanks to the perforation, the water-storing drainage membrane is permeable and can also be used for inverted roofs. This prevents a film of water from forming on the inverted roof insulation. The geotextile should be removed from walkable areas without vegetation. The base layer and the bedding material can then be applied directly on the dimpled membrane without changing the material, and then the pavement or slab covering can be laid on top of it.
