Composite geomembranes are widely used in channel anti-seepage projects. The extensive application and effectiveness of geosynthetics in civil engineering, especially in flood control and emergency rescue projects, have attracted great attention from engineers and technicians. For the application technology of geosynthetics, the state has put forward normative technical requirements in terms of anti-seepage, reverse filtration, drainage, reinforcement, protection, etc., which has greatly accelerated the promotion and application of new materials. This material has been widely used in canal anti-seepage projects in irrigation areas. Combined with construction practice, the application technology of composite geomembrane is briefly discussed.

Composite geomembrane is an impermeable material composed of geotextile and geomembrane. It is mainly used for anti-seepage. The composite geomembrane is divided into one cloth and one membrane and two cloths and one membrane. 1500g/m2, high physical and mechanical performance indicators such as tensile strength, tear resistance, bursting, etc., can meet the needs of civil engineering such as water conservancy, municipal administration, construction, transportation, subway, tunnel, etc. Due to the selection of polymer materials and the addition of anti-aging agents in the production process, it can be used in unconventional temperature environments.

performance

The composite geomembrane (composite anti-seepage membrane) is divided into one cloth and one membrane and two cloths and one membrane. The width is 4-6m, the weight is 200-1500g/square meter, and the physical and mechanical performance indicators such as tensile resistance, tear resistance and bursting High, the product has the characteristics of high strength, good elongation, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, and good anti-seepage performance. It can meet the needs of civil engineering such as anti-seepage, isolation, reinforcement, crack prevention and reinforcement in water conservancy, municipal administration, construction, transportation, subway, tunnel, and engineering construction. It is often used for anti-seepage treatment of dams and drainage ditches, and anti-fouling treatment of waste yards.
