Geotextiles

Pasminco-198
Non-woven Geotextiles provide excellent stability in civil engineering applications. These products form protective barriers and support underneath and can vent built-up liquids and gases beneath the surface. Non-woven geotextiles are used as a cushion for a geomembrane liner or for subsurface drainage, and in gas venting and drainage systems. A woven geotextile is a planar textile structure produced by interlacing two or more sets of strands at right angles. There are two types of strands: slit films, which are flat; and monofilaments, which are round. Woven slit-film geotextiles are generally preferred for applications where high strength properties are needed and filtration requirements are less critical. These fabrics reduce localised shear failure in weak subsoil conditions and aid construction over soft subsoils. Woven monofilament geotextiles are preferred for applications where both strength and filtration are a concern.
