Composite geotextile is mainly used in five fields
1. Environmental protection and sanitation. It has effectively solved the problem of urban solid waste polluting the environment and can avoid continuous pollution to the environment. 2. Water conservancy projects are used for dam foundation reinforcement, drainage plate drainage of groundwater, drainage and pressure reduction.
　　 3. Municipal construction engineering soft soil foundation reinforcement and drainage and other various anti-seepage projects
　　 4. Petrochemical system, anti-seepage of chemical sewage pond, anti-seepage of oil refinery sewage pond, anti-seepage and anti-corrosion of electroplating pickling pond, pipeline lining, etc.
　　 5. Road traffic facilities, anti-seepage diversion reinforcement under ballast, culvert and tunnel anti-seepage reinforcement groundwater drainage and circuit moisture protection).
Composite geotextile (composite geotextile) is divided into one cloth and one film and two cloth and one film, with a width of 4-6m, a weight of 200-1500g/m2, tensile, tearing, bursting and other physical mechanics The performance index is high, the product has the characteristics of high strength, good elongation performance, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance and good anti-seepage performance. It can meet the needs of civil engineering in water conservancy, municipal administration, construction, transportation, subway, tunnel, engineering construction, seepage prevention, isolation, reinforcement, crack prevention and reinforcement. Because it uses polymer materials and anti-aging agents are added to the production process, it can be used in unconventional temperature environments. Commonly used for anti-seepage treatment of dikes, drainage ditches, and anti-fouling treatment of waste yards. Function: Anti-seepage, isolation Uses: Geotechnical dam, rockfill dam, masonry dam and spread-pressure concrete dam; horizontal anti-seepage overlay on embankment and dam, vertical anti-seepage layer on foundation; tailing dam, sewage dam body and reservoir area ; Construction cofferdam; The wide application of composite geomembrane for channels and reservoirs has also played a protective role in the ecological environment.
