PM 3D- GEOTEX M20M
PM 3D-GEOTEX M20M is a lightweight, three-dimensional composite with an exceptionally high drainage capacity.
PM 3D-GEOTEX M20M is a lightweight, three-dimensional composite with an exceptionally high drainage capacity. The drainage core consists of robust polypropylene monofilaments with a high void ratio and is combined on the outside with a geotextile as a filter. On the backside, the composite is connected with a concrete-tight polymer-reinforced film. The monofilaments have a M-shaped double dimpled structure for a very good drainage capacity. As “flexible” drainage, the geosynthetic adapts perfectly to the substrate and can be used as permanent formwork between the retaining wall and the new structure to be built
