Products Introduction：
Geomembrane Pond is a pond system constructed with high-performance geomembranes as the core material. By laying geomembranes with special properties on the pond base and slope, a complete anti-seepage and isolation structure is formed. It breaks the limitation of traditional ponds relying on natural soil for anti-seepage, providing a stable and reliable environment for water storage, aquaculture, landscape and other needs. It is widely used in agriculture, aquaculture, municipal water conservancy and other fields, and is an important solution for achieving efficient water management in modern engineering.
Product Features：
1. Excellent Material: Made of high-quality polymer materials such as high-density polyethylene (HDPE) and ethylene vinyl acetate copolymer (EVA), it has excellent physical and mechanical properties, lightweight and strong toughness, and can adapt to the laying needs of different terrains.
2. Efficient anti-seepage: Geomembranes have a dense molecular structure and extremely low permeability, which can effectively prevent water from leaking into the soil, ensure the stability of the total amount of water in the pond, and reduce water resource loss caused by leakage. They are especially suitable for water scarce areas or scenarios with high water level control requirements.
3. Outstanding durability: It has good anti-aging performance, and can resist long-term ultraviolet radiation without embrittlement; At the same time, it is resistant to acid and alkali, chemical corrosion, and can adapt to various water quality environments that may exist in ponds. Its service life can reach 10-30 years, greatly reducing the cost of frequent renovations.
4. Environmentally friendly: The material itself has stable chemical properties, no harmful substance release, will not cause pollution to water bodies and surrounding soil, and can block heavy metals, impurities, etc. in the soil from entering the pond, creating a clean and safe environment for the water body.
5. Convenient construction: Geomembrane is lightweight, flexible, and easy to lay without the need for complex large equipment. It can be flexibly cut and spliced according to the shape and size of the pond, significantly shortening the construction period and reducing construction difficulty.
