Main features
The main characteristics of geomembranes are very distinct. Firstly, it has strong weather resistance and can resist the influence of natural environmental factors such as ultraviolet radiation and changes in high and low temperatures. Its performance is not easily degraded when exposed to the outside for a long time; Secondly, it has outstanding corrosion resistance and can withstand the erosion of chemical substances such as acid, alkali, and salt, extending its service life; Thirdly, the construction is convenient, the laying process is simple, and there is no need for complex equipment. The joints are made using hot melt welding and other processes, which are firm and reliable, and can effectively shorten the construction period; Fourthly, it is economical and practical. Not only is the procurement cost relatively reasonable, but the maintenance cost in the later stage is also low, and the comprehensive cost-effectiveness is high. At the same time, the material itself is non-toxic and harmless, which meets environmental protection requirements.

Product Application
Water conservancy engineering field
In the construction of reservoirs and dams, geomembranes are laid on the surface or inside of the dam body to form an anti-seepage layer, prevent water leakage from the reservoir, ensure the stability and safety of the dam, and reduce the risks of dam deformation and collapse caused by leakage. In channel engineering, it can be laid on the inner wall of the channel to prevent the infiltration and loss of water resources during transportation, improve the utilization efficiency of water resources, especially suitable for irrigation channels in arid areas.
Environmental engineering field
Landfills are an important application scenario for geomembranes. Laying them at the bottom and surrounding areas of landfills can effectively block the infiltration of leachate into the soil and groundwater, avoiding pollution to the surrounding environment. At the same time, it prevents groundwater from entering the landfill and reduces the amount of leachate produced. In sewage treatment tanks, geomembranes can serve as anti-seepage materials to prevent sewage leakage, ensure the normal operation of sewage treatment processes, and protect the surrounding soil and water environment.
Transportation engineering field
In the construction of roadbeds for highways and railways, geomembranes can be laid between the roadbed and the base layer to provide isolation, prevent mixing between different soil layers, avoid soil erosion and settlement damage, and enhance the stability of the roadbed. In tunnel engineering, it can serve as a waterproof layer to prevent groundwater from seeping into the interior of the tunnel, ensuring the safety of the tunnel structure and driving safety.
Mining engineering field
In the tailings pond of a mine, geomembranes are used for anti-seepage treatment in the pond area, preventing harmful substances in the tailings slurry from penetrating into the surrounding soil and water, and reducing the risk of environmental pollution. At the same time, geomembranes are also used for anti-seepage in sedimentation tanks, heap leaching tanks and other facilities during the mining process to ensure that the production process meets environmental standards.
Agriculture and Horticulture
Laying geomembranes in agricultural irrigation reservoirs and irrigation channels can reduce water leakage and improve water resource utilization efficiency. In horticultural planting, some greenhouse foundations or planting pools use geomembranes to prevent seepage, isolate soil, and control moisture and nutrients, creating a suitable environment for plant growth.
From water conservancy and environmental protection to transportation, mining, and even agriculture and horticulture, geomembranes play an indispensable role due to their excellent anti-seepage and isolation properties. It not only ensures the safe and stable operation of various projects, improves resource utilization efficiency, but also makes significant contributions to environmental protection, becoming a widely used and crucial material in modern engineering construction.
