PM 20-GEOTEX

Drainage membrane

PM 20-GEOTEX is a highly effective 20 mm high protection and drainage system designed as a special solution for especially high-performance horizontal and vertical surface drainage on all pressure-resistant surfaces. PM 20-GEOTEX consists of a 20 mm high dimpled membrane and a sturdy Typar geotextile. The smooth back side allows for a uniform and extensive load distribution on the waterproofing.

This double-layer system protects the waterproofing below it from mechanical damage and damaging thermal stresses. PM 20-GEOTEX has a pressure resistance of 180 kN/m² and is thereby capable of a load of up to 18 tonnes when installed. The high-performance product is available in the following widths: 0.5 m, 1.0 m, 1.5 m, 2.00 m. Its excellent water draining capacity is approx. 30 times higher than required by drainage standard DIN 4095.

PM 20-GEOTEX protects deep outer basement walls, earth-covered roofs of underground car parks, patios and green flat roofs against waterlogging. The moisture penetrates the geotextile and enters the ducts of the dimpled membrane, where it is securely drained. In the process, the geotextile acts as a filter and prevents the ducts from getting clogged up. The optimal high-performance geotextile boasts very high initial strength with minimum deformation under increasing working load.
