What is geomembrane?
Geomembrane takes plastic film as the anti-seepage base material, and is compounded with non-woven fabric. The anti-seepage performance of new material geomembrane mainly depends on the anti-seepage performance of plastic film. Plastic films for anti-seepage applications at home and abroad mainly include polyvinyl chloride (PVC), polyethylene (PE), EVA (ethylene/vinyl acetate copolymer). In tunnel applications, ECB (ethylene vinyl acetate modified asphalt blend geomembrane) is designed and used. They are polymer chemical flexible materials with small proportion, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance and good frost resistance.
Characteristics of geomembrane
The composite geomembrane is made of plastic film as the anti-seepage base material and non-woven fabric. Its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film. Plastic films used for seepage prevention at home and abroad mainly include polyvinyl chloride (PVC), polyethylene (PE), ethylene/vinyl acetate copolymer (EVA), which are polymer chemical flexible materials with small proportion, strong extensibility, high deformation adaptability, corrosion resistance, low temperature resistance and good frost resistance.
The service life of composite geomembrane is mainly determined by whether the plastic film has lost its anti-seepage and water separation function. According to the national standard of the Soviet Union, the polyethylene film with a thickness of 0.2m and stabilizer for hydraulic engineering can work for 40 to 50 years in clean water and 30 to 40 years in sewage. Therefore, the service life of composite geomembrane is sufficient to meet the service life of dam anti-seepage requirements.
Scope of application of geomembrane
Zhoutou reservoir dam was originally a core dam, but due to dam collapse, the upper part of the core wall was disjointed. In order to solve the problem of seepage prevention in the upper part, an anti-seepage inclined wall was added. According to the safety demonstration and analysis of Zhoutou reservoir dam, in order to solve the problem of weak seepage surface and dam foundation leakage caused by multiple landslides of the dam, seepage prevention bodies such as bedrock curtain grouting, contact surface grouting, backfill curtain of grab sleeve well and high-pressure jet grouting seepage prevention board wall are adopted in vertical seepage prevention. The upper inclined wall is covered with composite geomembrane for seepage prevention. The lower part is connected with the vertical cut-off wall and the upper part is 358.0m high.

- It can be cut up at a place where has a shear line, but there is a small piece which is can not be energized, and it is not safe. Clip must be used on one of the ends of the wire and then connect the wire, wrap with daub and black rubber in case of electric leakage, and on another end of the wire should be wrapped with professional daub and black rubber in case of electric leakage. It is about 200 watts per square meter. normal voltage of 220 volts is enough.
- Q: How do geomembranes prevent contamination of drinking water sources?
- Geomembranes prevent contamination of drinking water sources by acting as a physical barrier between the water and potential contaminants. They are impermeable and resistant to chemicals, preventing them from leaching into the water supply. Additionally, geomembranes can be installed as liners in reservoirs, ponds, and landfills, preventing any seepage or leakage of pollutants into the surrounding water sources.
- Q: Can geomembranes be used for wastewater ponds?
- Yes, geomembranes can be used for wastewater ponds. Geomembranes are impermeable liners that can effectively contain and prevent the leakage of wastewater. They are commonly employed in the construction of wastewater ponds to create an impermeable barrier, ensuring that the wastewater remains contained and does not contaminate the surrounding environment.
- Q: What static eliminator is the best for large production equipment of geomembrane?
- 3024-L remote static eliminator is the best. The highest working voltage of the production equipment can reach 180KV. Otherwise, the quality of the products will decline seriously. So it is of great importance to eliminate static which can avoid the interference to production. At the place for reeling after dividing and cutting in the production equipment, the voltage of static electricity can reach 10KV which can be reduced by this eliminator.
