Product Introduction
Harga HDPE Geomembrane is a waterproof and barrier type geotextile material mainly made of polymer materials such as polyethylene PE, polyvinyl chloride PVC, ethylene vinyl acetate copolymer EVA, etc. Its core function is to prevent water, liquid or gas from penetrating.
It is usually divided into homogeneous films made of a single material (such as HDPE geomembrane) and composite films made of non-woven fabric. The former is widely used in high demand scenarios due to its high strength and chemical corrosion resistance, while the latter enhances puncture resistance and friction resistance through non-woven fabric, adapting to more complex construction environments.
Its main characteristics include: excellent anti-seepage performance (extremely low permeability coefficient), resistance to chemical corrosion such as acid and alkali, strong anti-aging ability, stable mechanical performance (able to adapt to foundation deformation), light weight, convenient construction, and can be cut and spliced according to project needs.
The application areas cover water conservancy engineering (dam and reservoir anti-seepage), environmental engineering (landfill and sewage treatment plant anti-seepage), transportation engineering (highway and railway foundation waterproofing), mining (tailings pond anti-seepage), agriculture (irrigation pond, breeding pond lining), etc. It is a key material for achieving anti-seepage and isolation in engineering.

Product Application
Geomembrane, as a type of anti-seepage and barrier material with polymer as the core material, plays a key role in waterproofing and isolation in multiple engineering fields due to its excellent anti-seepage, corrosion resistance, and adaptability. It is an important material for ensuring engineering safety and environmental stability.
1. Water conservancy engineering: anti-seepage reinforcement of reservoirs and dams to prevent water leakage; The lining of water channels and artificial lakes can reduce water loss, especially in arid areas, and significantly improve water resource utilization efficiency.
2. Environmental protection engineering: the core of the anti-seepage system for landfills and hazardous waste disposal sites, which blocks the infiltration of leachate into soil and groundwater; The sedimentation tank and reaction tank of the sewage treatment plant are leak proof to prevent the diffusion of pollutants.
3. Transportation engineering: the waterproof layer of highway and railway subgrade to prevent groundwater from rising and eroding the foundation; The waterproof lining of tunnels and culverts ensures the durability of transportation facilities.
4. Mining and Agriculture: Bottom lining of tailings ponds and heap leaching ponds in mining to prevent slag wastewater pollution; The lining of water reservoirs and breeding ponds in agriculture reduces irrigation water loss and enhances the water retention capacity of aquaculture.
Different types of geomembranes (such as HDPE film, EVA film, etc.) will be selected according to the requirements of the scenario: HDPE film is often used in harsh environments such as landfills due to its high strength and corrosion resistance; EVA film has good flexibility and is suitable for projects with significant geological deformation. The core value of its application lies in its reliable anti-seepage performance, which balances engineering safety and environmental protection. It is an indispensable functional material in modern engineering.
