Zhonglong Non-woven Filament Geotextile is manufactured from high-quality PET (polyester) filament fibers, and is available in widths of 3–6 meters, lengths of 50–200 meters, and mass per unit area ranging from 100 to 800 g/m². It provides essential functions of filtration, drainage, separation, erosion control, and protection, and can also be combined with geomembranes or GCLs to form composite products, retaining the performance of the base materials while extending service life. This versatile geotextile is widely used for embankment and leachate filtration, soil and rock mixture separation, roadbed and building basement drainage, slope erosion control, and as upper and lower protective layers for waterproofing materials such as geomembranes and GCLs.
