Products Introduction：
Polyethylene Pond Liner is a flexible anti-seepage material designed specifically for pond and water feature engineering. It is made of high-density polyethylene (HDPE) or linear low-density polyethylene (LLDPE) as raw materials, and is produced through blow molding technology with a thickness of 0.5-1.5mm, commonly used specifications. Its core positioning is "an efficient water barrier for pond water bodies". With the dense molecular structure and flexible properties of polyethylene material, it solves the problems of natural pond leakage and difficult maintenance of artificial pond water level, while also considering ecological compatibility and construction convenience. It is suitable for various pond scenes such as family courtyard ponds, landscape water features, aquaculture ponds, etc. It is a key material for "water conservation, anti-seepage, and ecological protection" in pond construction.
Product Features：
1. Efficient water locking and anti-seepage, water-saving and worry free
The dense molecular structure of polyethylene results in a permeability coefficient of ≤ 1 × 10 ⁻¹² cm/s, almost eliminating water leakage and reducing pond water level loss rate by over 95%; Whether it is rainwater, pond water, or aquaculture water bodies, they can effectively block their infiltration into the ground, reduce the labor and water resource costs of frequent replenishment, especially suitable for arid areas or pond projects with valuable water resources.
2. Flexible and easy to shape, suitable for various pool shapes
The product has a fracture elongation rate of ≥ 500% (made of LLDPE material) and can be bent and folded freely, perfectly fitting the contours of circular, irregular, and varying depths of ponds. It can even adapt to landscape ponds with complex structures such as rockeries and stacked water, without any blind spots for seepage prevention; Lightweight (0.5mm thickness, about 500g per square meter), easy to handle and cut, ordinary scissors can adjust the size according to the pool shape, solving the pain points of rigid anti-seepage materials that are difficult to shape and prone to cracking.
3. Durable and durable, eco-friendly
After UV treatment, the performance degradation after 5 years of outdoor exposure is ≤ 8%, and it can withstand direct sunlight and wind and rain erosion; Anti puncture strength ≥ 200N, able to resist slight biting and friction from stones, tree roots, and aquatic organisms (such as fish and turtles) in the pond; The material is non-toxic and odorless, meeting food grade standards, and will not release harmful substances to pollute water bodies, ensuring the living environment of aquatic plants, fish, and other organisms.
4. Easy installation and simple maintenance
No professional mechanical equipment is required, only 2-3 people are needed to complete the laying: after cleaning the bottom of the pool, the membrane body can be directly unfolded, and the laying of ponds within 100 square meters can be completed within 1 day through overlapping, heat sealing, or special tape splicing; The surface is smooth and not easy to adhere to silt and algae. Daily cleaning only requires simple flushing, and it is resistant to acid and alkali corrosion. It can withstand changes in water quality in the pond (such as pH 6-9), and the maintenance cost in the later stage is extremely low.
5. Excellent cost-effectiveness and flexible customization
Compared to traditional concrete and clay anti-seepage methods, the material cost has been reduced by 30% -60%, and the construction period has been shortened by 50%; Support customized specifications with a width of 1-10m and any length, reducing the number of seams and minimizing the risk of leakage; We offer color options such as black (for heat absorption and insulation, suitable for aquaculture ponds) and blue (for simulating natural water bodies, suitable for landscape ponds), balancing functionality and aesthetics.
