Zhonglong Composite Geomembrane is manufactured by bonding a geotextile to one side (1G1M) or both sides (2G1M) of a geomembrane, and is available in widths of 4–6 meters, lengths of 50–100 meters, with geotextile options of 100–800 g/m² in either filament or staple fiber, using HDPE and PP/PET with optional carbon black. While retaining the inherent anti-seepage properties of the geomembrane, it provides additional functions of drainage, ventilation, and protection, reducing the need for secondary protective layers and extending the service life of engineering projects. It is widely used in landfill liners, wastewater treatment, hazardous waste containment, reservoir and canal lining, irrigation ponds, tailings ponds, heap leach pads, oil and gas exploration lining, pond liners, and biogas digesters.
