PM 3D-GEOTEX W8
PM 3D-GEOTEX W8 is a strong 8 mm high three-dimensional composite with an exceptionally high drainage capacity.
PM 3D-GEOTEX W8 is a strong 8 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 W-shaped structure for high compressive strength and 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.
