Geotextile fabric is a permeable material made from synthetic fibers such as polypropylene or polyester. It is designed to interact with soil and other materials in various engineering applications. Geotextiles can be classified into two main categories: woven and non-woven. Woven geotextiles are made by interlacing fibers, offering high tensile strength, while non-woven geotextiles are produced by bonding fibers together, providing excellent drainage and filtration properties.
