There are two basic types of woven geotextiles: slit-films which are made by weaving flat strands created by first slitting a plastic sheet; and monofilaments, which incorporate round strands that are extruded.
Woven slit-film geotextiles are typically preferred for applications where filtration requirements are less critical. These geotextiles aid in construction over soft or weak soils by providing separation and stabilization.
Woven monofilament geotextiles, are preferred for applications where both strength and filtration are a concern, such as shoreline rip rap applications.
