PM 3D- GEOTEX M20
PM 3D-GEOTEX M20 is a light 20 mm high three-dimensional composite with an exceptionally high drainage capacity.
PM 3D-GEOTEX M20 is a light 20 mm high three-dimensional composite with an exceptionally high drainage capacity. The core consists of robust polypropylene monofilaments with a high void ratio and is combined with a nonwoven geotextile filter on both sides. The monofilaments have a M-shaped double dimpled structure for a very good drainage capacity. As "soft" drainage, the geosynthetic adapts optimally to the substrate. Ideal for foundation and retaining walls, drainage as permanent formwork on diaphragm walls, extensively and intensively green roofs and underground car park ceilings.
