This geomembrane withstands UV radiation, extreme temperatures, and harsh weather without degradation. It’s resistant to a wide range of chemicals, acids, and alkalis, ensuring long - term stability in corrosive environments.
(4) Eco - Friendly:
Made from recyclable LLDPE materials, it aligns with green construction principles. Its long service life reduces replacement frequency, minimizing waste and environmental impact.
3. Applications
(1) Environmental Protection
Landfills: In large - scale landfill projects, the 1.5mm LLDPE Geomembrane acts as a crucial barrier, preventing harmful leachate from seeping into the soil and groundwater. For example, in urban landfill expansions, it helps protect the surrounding communities and ecosystems from contamination.
Waste Treatment Sites: When handling industrial or hazardous waste, the geomembrane’s chemical resistance ensures that it can safely contain pollutants. It has been successfully used in waste incineration plant leachate collection systems to prevent leaks.
Contaminated Soil Remediation: During soil remediation projects, the geomembrane can isolate polluted areas, preventing the spread of contaminants. In brownfield redevelopment, it’s often used to cap contaminated soil, creating a safe foundation for new construction.
(2) Water Engineering
Reservoirs: Whether it’s a small rural reservoir or a large - scale urban water supply reservoir, the 1.5mm LLDPE Geomembrane provides reliable waterproofing. In mountainous regions, its flexibility allows it to conform to the complex terrain, reducing water seepage and ensuring water storage integrity.
Irrigation Canals: For agricultural irrigation systems, the geomembrane lines canals to minimize water loss. This helps farmers save water resources and improve irrigation efficiency, especially in arid and semi - arid areas.
Fish Ponds: In fish farming, the geomembrane creates a clean and stable aquatic environment. It prevents the intrusion of soil particles and contaminants, maintaining good water quality and promoting healthy fish growth.
Water Storage Tanks: For above - ground or underground water storage tanks, the geomembrane provides an additional layer of protection against leaks. It’s commonly used in emergency water storage facilities and community water supply systems.
(3) Industrial Projects
Chemical Storage Areas: In chemical plants and refineries, the 1.5mm LLDPE Geomembrane is used to line storage tanks and containment areas for hazardous chemicals. Its excellent chemical resistance safeguards the ground from spills and leaks, reducing the risk of environmental disasters.
Industrial Wastewater Treatment Facilities: When treating industrial wastewater, the geomembrane lines treatment ponds and basins. It prevents the treated water from contaminating the soil and groundwater, while also protecting the structures from corrosion caused by the wastewater.
(4) Construction
Basement Waterproofing: In building construction, the geomembrane effectively blocks moisture from entering basements. This protects building structures from water damage, prevents mold growth, and improves the comfort and durability of the building.
Artificial Lakes: For urban landscaping projects, the geomembrane is used to create beautiful artificial lakes. It ensures long - term water retention, allowing for the creation of scenic water features in parks, residential communities, and commercial developments.
Tunnels: In tunnel construction, the geomembrane provides waterproofing and protection for the tunnel lining. It helps prevent water seepage into the tunnel, which can cause structural damage and safety hazards. Additionally, it can act as a barrier against soil and rock pressure.
Ecological Wetland Parks: When constructing ecological wetland parks, the 1.5mm LLDPE Geomembrane is used to create water - retaining areas and filter beds. It helps maintain the water level and quality of the wetland, providing a suitable habitat for various plants and animals.
Tailings Ponds: In mining operations, the geomembrane is used to line tailings ponds, preventing the leakage of toxic tailings and protecting the surrounding environment. Its high strength and durability can withstand the heavy loads and harsh conditions of the tailings storage area.
