The 2mm HDPE geomembrane is specially designed for tailings ponds. It is made from high-density polyethylene (HDPE). This material has strong chemical stability and can resist the erosion of various acidic and alkaline substances in the tailings. The product has excellent anti-seepage performance, effectively preventing the contamination of soil and groundwater by tailings seepage. Its thickness provides good puncture resistance and tear resistance, and it is not easily damaged under the heavy pressure of tailings. Moreover, it has excellent weather resistance and anti-aging properties, and can be used stably in tailings ponds for a long time.

Application fields
1. Environmental Engineering: Used for anti-seepage of the bottom and slopes of landfill sites and hazardous waste treatment sites, to prevent the leakage of leachate and protect soil and groundwater from pollution; construction of anti-seepage layers for regulating ponds and anaerobic tanks in sewage treatment plants.
2. Water Conservancy Engineering: Anti-seepage lining for reservoirs, lakes, and rivers to reduce water leakage losses; anti-seepage reinforcement of dams and channels to enhance the durability of the projects.
3. Agriculture and Aquaculture: Anti-seepage treatment for artificial lakes, fish ponds, and shrimp ponds to maintain stable water levels and prevent nutrient loss; construction of anti-seepage channels for agricultural irrigation systems to improve water resource utilization.
4. Energy and Industry: Anti-seepage layers for tailings dams and slag disposal sites to prevent the migration of heavy metals; anti-seepage and anti-humidity measures for oil tank foundations and chemical pools to ensure the safety of industrial facilities.
5. Transportation and Infrastructure: Anti-humidity and anti-seepage layers for tunnels and subways to reduce groundwater infiltration; isolation layers for roadbeds to prevent frost heave and thawing damage.
Application Case
In the membrane covering renewal project of the second-stage regulating pond of the domestic waste landfill in Shigatse City, 2mm HDPE geotextile membrane was adopted, which effectively prevented the leakage of waste leachate, isolated the diffusion of foul odors, achieved rainwater and sewage separation, and improved the environmental performance of the landfill site.
