CM8 Geotex Drainage Membrane

Typically used to isolate and protect the basement structure from surrounding  soil and relieve hydrostatic pressure by promoting the flow of ground water away from the face of the structure. The Geotexile drainage membrane provides excellent protection from root penetration and can also increase the structures thermal insulation.

CM8 Geotextile Membrane dual layers comprise of Wykamol’s CM8, 8 mm studded HDPE membrane and a nonwoven geotextile manufactured from UV stabilised, high tenacity, virgin polypropylene fibres that have been mechanically entangled to provide high strength, high extensibility, high loft and excellent abrasion characteristics. The geotextiles are also thermally treated to reduce thickness while maintaining excellent mechanical properties.
