PM P 20-GEOTEX 150 is a water-storing drainage membrane and is the ideal solution for extensive and intensive green roofs.
PM P 20-GEOTEX 150 offers a multiple of drainage and water storage capacity, assuming the function of a protective, filter, seepage and water storage layer in the green roof.
The 20 mm studs have a water storage capacity of approx. 6 litres/m². The compressive strength of approx. 150 kN/m² offers a high level of safety and thus corresponds to a compressive load capacity of approx. 15 tonnes per m². The 20 mm dimpled sheeting also offers a disproportionately high drainage capacity. It can therefore also be used with very long drainage lengths and/or very low roof pitches. The planting substrate can be applied directly as the geotextile is already integrated. This saves an additional work step. Thanks to the perforation, the water-retaining drainage membrane is open to diffusion and can also be used for inverted roofs. This means that no water film can form on the inverted insulation.
