Geotextiles Polyester Geotextile

Polyester Geotextile are multi-purpose fabrics that are felt-like in appearance. The main functions for these products are filtration and separation. The most common nonwoven is a needle-punched product. Staple fibers or continuous filaments are bonded by mechanically entangling the fibers with barbed needles.In a granular or what is sometimes known as a single layer green roof the filter fabric is used to separate larger granular material for drainage from finer material in the growing media. The ability of the geotextile to allow water permeability is referred to as hydraulic conductivity by permittivity.
