Geomembranes provide a barrier function to protect the environment – water, soil, and air – and to contain liquids and gases. Changxing produces various types of polymeric geosynthetic barriers for demanding applications, from mining and any class of landfill, to petrochemical, oil and gas industries, and aquaculture.

1. The geomembrane is suitable for environmental protection and sanitation, such as landfill, sewage treatment plant, power plant regulating pool, industrial and hospital solid waste, etc;
2. The geomembrane is suitable for water conservancy projects, such as seepage prevention, leakage stoppage, reinforcement, seepage control of water channel, vertical core wall, slope protection, etc;
3. The geomembrane is suitable for Municipal Engineering: subway, building underground engineering, planting roof, roof garden, sewage pipe seepage control, etc;
4. The geomembrane is suitable for Gardens: artificial lake, river course, reservoir, pond bottom of golf course, slope protection, waterproof and moisture-proof of green lawn, etc;
5. The geomembrane is suitable for petrochemical industry: chemical plant, oil refinery, oil storage tank, chemical reaction tank, sedimentation tank lining, secondary lining, etc;
6. The geomembrane is suitable for mining industry: washing pond, heap leaching pool, ash yard, dissolving pool, sedimentation tank, storage yard, bottom lining seepage control of tailings, etc;
7. The geomembrane is suitable for traffic facilities, such as highway and culvert;
8. The geomembrane is suitable for agriculture: anti-seepage of reservoir, drinking pool, storage pond, irrigation system, etc;
9. The geomembrane is suitable for aquaculture industry: intensive and industrialized aquaculture pond, fish pond, shrimp pond lining, sea cucumber enclosure slope protection, etc;
10. The geomembrane is suitable for salt industry: salt field crystallization pool, brine pool, etc.
Construction method of Geomembrane:
1. The slope should be laid from the top to the bottom, and should not be pulled too tightly. A margin of 1.50% should be reserved for local subsidence and tension.
2. The longitudinal joints of two adjacent frames shall not be on a horizontal line, and shall be staggered by more than 1m;
3. The longitudinal joint should be more than 1.50M away from the dam toe and bending foot, and should be set on the plane;
4. When the slope is laid, the film spreading direction should be basically parallel to the slope line.
5. In construction, the sand or clay with small diameter should be used to level the base surface, and then the geomembrane should be laid. The geomembrane should not be stretched too tightly. The parts embedded in the soil at both ends are wavy. On the geomembrane, a transition layer of about 10cm is paved with fine sand or clay.
