HDPE Geomembrane Liner
1. Strong impermeability
With an extremely low permeability coefficient, it can almost completely prevent the penetration of liquids and gases. Combined with seamless connection technologies such as hot melt welding, it can avoid the risk of leakage.
2. Good durability
With the addition of UV absorbers and other agents, it is resistant to erosion by chemical substances such as acids, alkalis, salts and oils, and has excellent anti-aging performance.
3. Convenient construction
Light in weight and highly flexible, it is easy to transport and lay, capable of adapting to complex terrains.
4. Economic advantage
Compared with traditional concrete anti-seepage, it can save 30% to 50% of the cost, and there is no need for curing time, and the later maintenance cost is also low.
Product Introduction:
HDPE geomembrane liner is made of high-density polyethylene (HDPE) resin as the core raw material and formed through extrusion, blow molding and other processes. It has excellent anti-seepage performance and physical and mechanical properties. Its molecular structure is compact, with high chemical stability. It can effectively resist the erosion of various chemical media, and is resistant to ultraviolet rays, high and low temperatures, with a long service life.
Product parameters:
parameters | Details |
thickness | It is usually between 0.12 and 4.0mm, and the common ones are 0.5mm, |
width | Generally, 1-10m, such as 7.0m and 8.0m, are more commonly used |
length | Conventional 50-150 meters, produced as required |

Product application:
1. Environmental protection projects: Anti-seepage at the bottom and slopes of landfill sites and sewage treatment plants to prevent leachate from seeping through and polluting soil and groundwater. Anti-seepage isolation of hazardous waste treatment plants to prevent the spread of harmful chemicals.
2. Water conservancy projects: Anti-seepage layers for reservoirs, DAMS and canals to reduce water seepage and loss and enhance project stability; Leak-proof substrates for artificial lakes and rivers to maintain the landscape effect of water bodies.
3. Chemical and Mining industries: Anti-corrosion gaskets for chemical tanks and storage areas, resisting erosion by acid and alkali solutions; The anti-seepage layer of tailings ponds and smelting pools prevents heavy metal ions from polluting the surrounding environment.
4. Agriculture and aquaculture: Anti-seepage substrates for fish ponds and shrimp ponds to maintain stable water levels; Anti-seepage treatment of reservoirs and irrigation channels to improve the utilization rate of water resources.
5. Energy Engineering: Anti-seepage for LNG storage tank foundations and petrochemical sites to prevent the leakage of flammable, explosive or toxic liquids and avoid safety accidents.
Company advantages:
The geomembrane of Haoyang Environment has significant advantages. It is a flexible material with an elongation at break of ≥850%, capable of adapting to foundation settlement and terrain deformation. Even in the face of uneven settlement at the bottom of the reservoir or on the slope, it is not prone to cracking. Its anti-seepage coefficient is extremely low, ≤1×10-13 m/s, and it has an excellent waterproof effect. The larger width reduces the number of construction joints and lowers the risk of leakage. The environmental stress cracking resistance performance is ≥700 hours, and it can ensure no cracking even in complex environments. Moreover, it contains no plasticizers and will not pollute water bodies, making it environmentally friendly and green. Whether it is water conservancy projects or the field of environmental protection, Haoyang Environmental geomembrane is a reliable choice.
