These are manufactured by weaving flat strands of polypropylene that are created by slitting a plastic sheet. They are often times used as backing material for sediment control solutions such as silt fencing due to their ability to remain intact while retaining sediment when installed vertically between posts. This form of geotextile also aids in construction over soft or weak soils by providing separation and minor stabilization for light duty, load support applications.
Slit Film Woven Geotextiles are one of the more basic versions of geosynthetic fabrics. Thus, offering up an economical price point to the market. They are best suited for separation of materials in light load applications with adequate drainage. Silt film woven geotextiles tenure in the industry has lead to the discovery of using the fabric in many different applications.
