Nonwoven Geotextiles

Non-woven geotextiles are synthetic fabrics made by bonding polypropylene or polyester fibers into a flexible, felt-like structure using mechanical (needle-punching), thermal, or chemical processes. Unlike woven geotextiles, which are interlaced like traditional textiles, non-wovens form a random, web-like matrix that offers excellent filtration and drainage capabilities. These fabrics are commonly used in civil construction for soil separation, subsurface drainage, erosion control, and geomembrane protection. Their high-water flow rates and ability to conform to uneven surfaces make them ideal for applications like roadway underlayment, landfill liners, and stormwater systems. While they generally offer lower tensile strength than woven types, non-wovens excel in hydraulic performance and are often preferred where filtration and permeability are critical.
