Product Applications：
High-density polyethylene (HDPE) pond liners, with their superior impermeability, weather resistance, chemical stability, and ultra-long service life, have become a core seepage prevention solution in various fields such as environmental protection, water conservancy, agriculture, and industry. They are widely applicable to various scenarios, from civil landscaping to large-scale engineering projects. Specific applications include:
1. Environmental Protection and Waste Treatment
As a key barrier for ecological protection, this liner plays an irreplaceable role in environmental engineering. In municipal solid waste landfills, industrial solid waste treatment plants, and hospital waste landfill projects, it is used as the primary or secondary impermeable layer, effectively preventing harmful substances in leachate from seeping into the soil and groundwater. Combined with bentonite waterproofing blankets, it forms a "rigid-flexible complementary" multi-barrier system, providing long-term protection for the surrounding soil and groundwater environment. In wastewater treatment plants, it is widely used as the lining for facilities such as wastewater equalization tanks, aeration tanks, and sedimentation tanks. It withstands acidic and alkaline environments with a pH range of 2-12, preventing secondary pollution caused by leakage of chemical wastewater and domestic sewage. In a chemical plant renovation project, the groundwater pollutant concentration decreased by 60% the following year after laying a 2mm thick lining. Furthermore, it is also suitable for power plant equalization tanks, biogas digesters, and solid waste disposal sites. With its excellent resistance to chemical erosion, it resists the erosion of various corrosive substances and is recyclable, aligning with environmental protection and circular economy principles.
2. Water Conservancy and Municipal Engineering
In water conservancy construction, this lining is a core material for improving project stability and water resource utilization. It can be used for seepage prevention, plugging, and reinforcement of river, lake, and reservoir dams, as well as for lining canals and irrigation channels, effectively reducing water resource leakage and loss while enhancing the structural strength of dams and slopes to resist water erosion. In municipal engineering, it is widely used in underground utility tunnels, subway tunnel linings, building foundation waterproofing, and waterproofing layers for roof gardens and green roofs. Its excellent flexibility allows it to adapt to complex terrain, making construction convenient and quick. Furthermore, it is suitable for seepage prevention in highway and expressway foundations, especially for expansive soils, collapsible loess, and saline-alkali land subgrades. It prevents salt backflow and water infiltration, ensuring the stability of the road foundation and reducing problems such as road surface cracking and collapse.
3. Agriculture and Aquaculture
This liner provides a highly efficient, water-saving, and quality-enhancing solution for agricultural production and aquaculture. In agricultural irrigation, it is used for seepage prevention in reservoirs, ponds, and irrigation systems. A village in Northwest China used it to build a rainwater collection pond, successfully preventing salt backflow from saline-alkali land. The stored rainwater could still meet the irrigation needs of goji berry seedlings three months later, significantly reducing crop scorching. In aquaculture, whether it's fish and shrimp ponds, sea cucumber enclosures, intensive factory-style aquaculture ponds, or lotus root and other aquatic crop planting ponds, laying lining mats allows for precise water control, preventing water and feed leakage. This can save half the water consumption per acre of fishpond annually, while also preventing lotus roots from growing too deep, reducing harvesting difficulty. Its non-toxic and environmentally friendly properties do not harm aquatic organisms and can also prevent pesticides and fertilizers from seeping into surrounding farmland, significantly improving the quality and safety of aquatic products and crops. In salt production, it can also be used as a covering material for salt crystallization ponds and brine pools, ensuring water retention and purity control during the salt-making process.
4. Landscape and Leisure Facilities
In the construction of landscape and leisure facilities, this lining mat is widely used due to its aesthetically pleasing and practical characteristics. In artificial lakes, landscape waterways, golf course ponds, and villa gardens, it can quickly construct a stable impermeable layer, ensuring a constant water level and preventing soil softening and damage to landscape facilities caused by water seepage. Its excellent compatibility allows it to be paired with various aquatic plants and landscape decorations without compromising ecological aesthetics. In recreational facilities, this liner is used as the core of impermeability in water park swimming pools, wading pools, artificial waterfalls, and in park and resort reservoirs and landscape fountains. Its strong tear and puncture resistance allows it to withstand the pressure from large numbers of visitors and mechanical operations. It is also resistant to UV aging and does not easily become brittle or crack even after long-term outdoor exposure, reducing maintenance frequency and costs.
5. Industrial and Special Engineering Fields
In industrial production and special engineering scenarios, the corrosion resistance and high strength of this liner are fully utilized. In the petrochemical industry, the liners for oil storage tanks, chemical reaction tanks, and sedimentation tanks in chemical plants, refineries, and gas stations effectively resist the erosion of petroleum and chemical raw materials, preventing leaks and pollution. In the mining sector, the linings for washing and beneficiation tanks, heap leaching tanks, tailings ponds, and dissolving tanks prevent the seepage of industrial waste and wastewater containing heavy metals, protecting the ecological environment of mining areas. To meet the needs of different industrial scenarios, the liners are available in various thicknesses. For heavy-duty applications such as industrial waste landfills, thicker models of 2.5 mm or more can be selected, capable of withstanding heavy machinery pressure without damage. Furthermore, they are suitable for special scenarios such as tunnel engineering, high-speed rail anti-slip layers, and temporary disaster relief facilities. In the Libyan desert oil field project, they successfully withstood the extreme test of a diurnal temperature range of 80°C without exhibiting brittle deformation, demonstrating extremely strong environmental adaptability.
High Density Pond Liner (HDPE) is a core seepage control material that combines superior performance with wide applicability. Made from high-quality high-density polyethylene, it achieves strong seepage control thanks to its extremely low permeability coefficient. It also possesses excellent tear and puncture resistance, UV resistance, high and low temperature resistance, and acid and alkali resistance, with a service life of 20-30 years. Its good flexibility allows it to adapt to various irregular terrains, making construction convenient and maintenance costs low. Its non-toxic and environmentally friendly properties ensure the safety of aquatic life and conform to the concept of recycling. This product is widely used in environmental waste treatment, water conservancy and municipal engineering, agriculture and aquaculture, landscaping, and special industrial scenarios. It solves the pain points of traditional seepage control materials being easily damaged and leaking, while meeting the differentiated needs from small-scale civilian applications to large-scale industrial projects. It is an ideal seepage control solution for improving project stability, saving resources, and protecting the ecological environment.
