Geomembrane is a thin film material made of synthetic polymers (such as polyethylene, polypropylene, etc.), which is usually used for water-soil separation, isolation, and anti-seepage. In the field of aquaculture, geomembrane liners are widely used at the bottom and around aquaculture ponds and aquaculture water bodies. Their main function is to prevent the infiltration between water and soil, the loss of pollutants, and ensure the stability of the water quality of aquaculture water bodies.

Geomembrane refers to a thin film material made of polyethylene (PE), polypropylene (PP) and other plastics through special processing. It has strong waterproof, isolation, reinforcement and other functions, and is widely used in civil engineering, environmental protection engineering, construction engineering, agriculture and other fields.

There are many ways to dispose of garbage, and landfill is still the main method in most areas. The national environmental protection regulations are relatively loose, and landfills do not adopt modern anti-seepage measures, resulting in frequent problems such as groundwater pollution and leachate leakage. South American countries have begun to vigorously promote modern landfill technology and adopt geomembrane anti-seepage systems to reduce environmental pollution and improve the safety of landfills.

Geosynthetics refer to synthetic materials used in civil engineering, transportation engineering and environmental engineering, mainly used for enhancing soil performance, anti-seepage, drainage, reinforcement and other purposes. According to different uses and structures, geosynthetics mainly include the following categories

Geogrid is a geosynthetic material used to enhance soil stability, improve engineering bearing capacity and reduce settlement deformation. It is usually made of high-strength polymers (such as polypropylene, polyethylene, polyester or glass fiber) and is formed into a mesh structure by stretching, welding or weaving.
