Water Conservancy Project Use Composite Geomembrane
Composite Geomembrane (Geotextile-Geomembrane Composite) is created by heat-bonding a nonwoven geotextile layer to a geomembrane. This composite combines the benefits and features of both materials. The geotextile enhances the system by offering better puncture resistance, tear propagation control, and improved frictional properties, which help reduce sliding. Additionally, the geotextile itself contributes tensile strength to the overall structure.

Applications of Composite Geomembranes:
Water Conservancy: Composite geomembranes are ideal for applications in water conservation, including anti-seepage, sealing, and reinforcement of dams, riverbanks, lakes, and reservoirs. They are also effective for canal lining, vertical core walls, and slope protection.
Environmental Protection & Sanitation: They are widely used in environmental projects such as landfills, sewage treatment plants, power plant conditioning pools, and the management of industrial and hospital waste.
Landscaping & Recreation: In landscaping, composite geomembranes are utilized in artificial lakes, rivers, reservoirs, golf course ponds, slope stabilization, and the creation of green lawns.
Municipal Engineering: They are commonly applied in municipal projects, including subways, underground building structures, green roofs, roof garden drainage, and sewage pipelines.
Mining & Waste Management: Composite geomembranes are used in mining applications such as washing tanks, heap leaching tanks, ash dumps, dissolution tanks, sedimentation tanks, and tailings pond liners to prevent seepage.
Petrochemical & Chemical Industries: These geomembranes are effective for petrochemical plants, refineries, oil storage tanks, chemical reaction tanks, secondary lining for sedimentation tanks, and other chemical containment systems.
Aquaculture: In aquaculture, composite geomembranes are used for intensive farming ponds, fish ponds, shrimp ponds, and sea cucumber farming, providing reliable slope protection and water containment.
Salt Industry: They are also used in the salt industry, including in crystallization ponds, brine pond covers, and salt production facilities, ensuring efficient sealing and protection.
Agriculture & Irrigation: Composite geomembranes are applied in agricultural fields, including reservoirs, drinking water storage pools, irrigation systems, and anti-seepage protection for agricultural ponds.
Transportation Infrastructure: They are used in transportation projects for reinforcing foundations in highways, and preventing seepage in culverts, contributing to the longevity of infrastructure.
