Advantages

Textured geomembrane is an extremely low permeability synthetic membrane lining or barrier used with any geotechnical related material to control fluid (or gas) migration in a man-made project, structure or system. Geomembranes are made from relatively thin continuous polymer sheets, but they can also be made by impregnating geotextiles with bitumen, elastomer or polymer sprays, or as multilayer bituminous geocomposites. Continuous polymer sheet geomembranes are by far the most common.

The materials used in the HDPE textured geomembrane are all raw materials. The principle of anti-seepage is ordinary physical changes and does not produce any harmful substances. It is the first choice for breeding and drinking pools.

High mechanical strength. HDPE textured geomembrane has good mechanical strength, the tensile strength at break is 28MP, and the elongation at break is 700%.

Good welding effect. HDPE textured geomembrane is welded with a special welding machine, and the welding effect is very good. The strength of the weld is greater than that of the base material, and it is convenient for construction.

Low cost and high benefit. HDPE textured geomembrane adopts new technology to improve the anti-seepage effect, but the production process is more scientific and fast, so the product cost is lower than traditional waterproof materials. According to actual calculations, the general engineering of HDPE anti-seepage membrane is used to save about 50% of the cost.

Anti-aging performance. HDPE textured geomembrane has anti-aging, anti-ultraviolet and anti-decomposition capabilities, and can be used exposed, providing a good material for environmental anti-seepage.

7.Anti-plant root system. HDPE anti-seepage membrane has anti-puncture ability and can resist most plant root systems.

8.Fast construction speed. HDPE textured geomembrane has high flexibility. There are various specifications and laying forms to meet the anti-seepage requirements of different projects. It adopts hot-melt welding, high weld strength and convenient construction.

Summary

According to the experience of successful international cases, a layered anti-seepage structure layer with HDPE textured geomembrane as the core is adopted to form an isolation layer at the bottom and surrounding of the landfill to prevent leachate from polluting groundwater, reduce the amount of leachate produced, and achieve seepage. The split discharge of filtrate, surface water and groundwater can effectively achieve the purpose of anti-seepage and environmental protection. At present, geomembrane has been widely used in urban domestic waste landfills in various countries, and the design (thickness, strength, leakage, slope stability, etc.) and construction technology of geomembrane have been gradually mastered by engineering and technical personnel in various countries. The protection measures of geomembrane construction are very important. The construction unit needs to have a perfect construction organization design to ensure that the geomembrane will not leak due to damage by stones, sharp objects, and human factors.
