Nonwoven geotextiles are multi-purpose fabrics that are “felt-like” in appearance and feel. 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.
The primary benefits of nonwoven geotextiles include improving drainage conditions and separating changes in aggregate size. Pooling or standing water can lead to the saturation of soils or aggregate, which creates soft spots within a road or lot. Nonwoven geotextiles are an excellent way to distribute water evenly across a large surface area, as well as drain water away from high traffic areas or applications. Nonwoven geotextiles ability to provide separation between different aggregate diameters is key to preventing the intermingling of fill material, which leads to settlement and surficial issues.
