LDPE geotextile membrane (low-density polyethylene geotextile membrane) is a flexible waterproof and anti-seepage material mainly made of low-density polyethylene (LDPE) resin, produced through blow molding or cast film processes. It possesses excellent flexibility, extensibility, chemical corrosion resistance and deformation adaptability, and is widely used in fields such as water conservancy, environmental protection, transportation, and agriculture.

Main features of LDPE geotextile membrane
1. Good flexibility
The LDPE geotextile membrane has a low crystallinity and a high elongation at break (usually between 100% and 700%), thus having good flexibility and extensibility, which can adapt to complex terrain and uneven subsidence of the base layer.
Chemical corrosion resistance
The LDPE geotextile membrane has good tolerance to acids, alkalis, salts and other chemical substances, and is suitable for corrosive environments such as chemical plants and landfill sites.
2. Strong adaptability to deformation
Due to its excellent flexibility and extensibility, the LDPE geotextile membrane can adapt to minor deformations of the base layer and is less likely to rupture due to stress concentration.
3. Convenient construction
The LDPE geotextile membrane is lightweight and soft, easy to lay and weld, with high construction efficiency.
4. Lower cost
Compared with high-density polyethylene (HDPE) geotextile membrane, the cost of LDPE geotextile membrane is relatively lower, with high cost-effectiveness.

Application fields of LDPE geotextile membrane
1. Water conservancy engineering
Used for anti-seepage treatment of reservoirs, dams, channels, artificial lakes and other projects to prevent water leakage and soil erosion.
2. Environmental protection engineering
Used for anti-seepage of the bottom and side walls of projects such as landfill sites, sewage treatment plants and hazardous waste treatment sites to prevent harmful substances from penetrating and polluting soil and groundwater.
3. Transportation engineering
Used for waterproofing and anti-seepage of roads, railways, tunnels and other projects to protect the subgrade and structural safety.
4. Agricultural engineering
Used for anti-seepage of agricultural facilities such as fish ponds, shrimp ponds, reservoirs and irrigation channels to improve water resource utilization efficiency.
5. Mining engineering
Used for anti-seepage of projects such as tailings dams, heap leaching pools and washing pools to prevent mine waste and wastewater from polluting the environment.
