Geotextiles are permeable polymer sheets that are produced in woven or non-woven form and are usually made of polyester, polypropylene, and nylon fibers. The most important properties of geotextiles are high tensile strength and resistance to soil destructive factors. The use and sale of geotextiles in the fields of drainage filtration, soil reinforcement, separation and protection.

Production and sale of geotextiles take place in two general categories. If the polymer fibers are woven by knitting machines in the form of two sets of yarns perpendicular to each other (warp and weft), it is called woven. Non-woven geotextiles are composed of regular fibers formed in random patterns in a plate structure. In these geotextiles, the fibers are joined together by chemical, thermal, or mechanical bonding. These plates vary in weight, pore size, fiber diameter, thickness and uniformity.
