Product Description

As an efficient waterproof material, geomembrane is widely used in anti-seepage projects in many fields due to its excellent performance. HDPE geomembrane is made of high-density polyethylene as the core material, with ultra-high anti-seepage, extremely strong chemical corrosion resistance (adaptable to strong acid, alkali, oil environment) and resistance to mechanical damage. It is especially suitable for harsh scenes such as landfills, chemical storage tanks and large reservoirs; Geomembrane supports rapid welding construction, has long-term durability (lifespan of more than 50 years) and environmental protection and economy. Through standardized laying and testing, it can significantly improve the efficiency of engineering anti-seepage and reduce environmental risks.
