Plastic Flexible Material for Water Storage
Geomembranes are synthetic impermeable barriers widely used in engineering and environmental projects to control fluid migration. Made from polymeric materials such as high-density polyethylene (HDPE), polyvinyl chloride (PVC), and linear low-density polyethylene (LLDPE), these thin, flexible sheets excel in preventing leaks, contamination, and soil erosion. Their versatility and durability make them indispensable in modern infrastructure and environmental protection.

Geomembrane in different engineering applications and advantages:
I. Application Areas
Hydraulic Engineering
Reservoir/Canal Seepage Prevention: Used to prevent water leakage and improve water storage efficiency (e.g., HDPE geomembranes).
Dam Reinforcement: Combined with geotextiles to enhance structural stability.
Environmental Engineering
Landfill Liners: Serve as impermeable barriers to prevent contaminants from leaching into soil (commonly 1.5-2.0mm thick HDPE geomembranes).
Wastewater Treatment Ponds: Corrosion-resistant materials prevent chemical leakage.
Transportation Engineering
Road/Railway Subgrades: Isolate groundwater to prevent frost heave and subsidence.
Tunnel Waterproofing: Applied to inner walls to reduce groundwater erosion.
Mining Engineering
Heap Leaching Pads/Tailings Storage: Prevent leakage of chemical solutions (e.g., copper leaching fluids).
Acid Wastewater Containment: Acid-resistant geomembranes (e.g., PVC) mitigate corrosion.
Agriculture
Irrigation Ponds: Reduce water loss, especially in drought-prone regions.
Aquaculture Ponds: Prevent water contamination of soil.
