In the construction of water conservancy projects, the anti-seepage treatment of reservoirs is a crucial task. Reservoir anti-seepage geomembrane is a commonly used anti-seepage material, widely applied in various reservoir projects. It plays a pivotal role in ensuring the normal operation of reservoirs, the effective storage of water resources, and the stability of the surrounding ecological environment.

Reservoir impermeable geomembrane
Product Overview
Reservoir impermeable geomembrane is primarily made of high-density polyethylene (HDPE), hence also known as polyethylene geomembrane. This geomembrane exhibits high chemical stability, weather resistance, and corrosion resistance, making it widely used in reservoir impermeable projects. It possesses excellent strength and toughness, allowing it to adapt to various construction conditions and foundation deformations.
Product Features
Impermeability: Geomembrane has an extremely low permeability coefficient, generally reaching 10⁻¹¹ cm/s, which enables it to effectively prevent water infiltration, significantly reduce water loss in reservoirs, and ensure the water storage function of reservoirs.
Chemical stability: It can resist the erosion of various chemicals, including acids, alkalis, salts, etc., and maintain stable performance in reservoir environments with different water qualities, ensuring a long service life.
Mechanical strength: It possesses high tensile strength and tear resistance, making it less prone to damage during construction. Furthermore, it can withstand soil pressure, water pressure, and other external forces during long-term use, maintaining structural integrity.
Weather resistance: It has good tolerance to climatic factors such as ultraviolet rays and temperature changes. Whether in hot and humid regions or cold and frozen environments, geomembrane can maintain its physical properties and will not rapidly deteriorate due to climatic conditions.
Construction convenience: Geomembrane is lightweight, making it easy to transport and lay. Its flexible nature allows it to adapt to various complex terrains and landforms. It can be spliced through welding or other methods, resulting in high construction efficiency and effectively shortening the project duration.
Application areas and cases
Seepage prevention for main dam and auxiliary dam of reservoir: Geomembrane is laid on the upstream face of the dam body of the reservoir to form a continuous seepage prevention barrier, preventing reservoir water from leaking into the dam body and avoiding structural instability of the dam due to leakage. For example, when reinforcing the dam seepage prevention in Wucheng, Dezhou, Shandong Province, 200g Sentai polyethylene geomembrane was used. After years of operation, the leakage amount of the dam body has been significantly reduced, effectively ensuring the safety of the dam.
Reservoir bottom seepage prevention: Covering the entire bottom of the reservoir, it prevents the reservoir water from infiltrating into the ground, reducing the impact on the surrounding groundwater level. At the same time, it can also prevent groundwater pollution to the reservoir water, maintaining the stability of reservoir water quality. The newly built reservoir in Changsha, Hubei Province, adopts a large area of geomembrane for reservoir bottom seepage prevention treatment, successfully achieving efficient water storage and water quality protection of the reservoir.
Channel Seepage Control: Irrigation channels connected to reservoirs utilize geomembranes for seepage control, which can reduce water loss during channel conveyance, enhance water resource utilization efficiency, and ensure water supply for farmland irrigation. In the channel renovation project in Datong, Shanxi Province, the application of geomembranes significantly improved the water utilization coefficient of the channels and effectively expanded the irrigation area.
Key points of construction and quality control
Key points of construction: Before laying, the foundation must be leveled and cleared of sharp debris to prevent punctures in the geomembrane. During the laying process, care should be taken to avoid wrinkles in the geomembrane and ensure it remains flat and smooth. When welding, it is necessary to strictly control parameters such as welding temperature and speed to ensure the weld is strong and sealed.
Quality control: During the construction process, it is necessary to inspect the material quality of the geomembrane, including indicators such as thickness and tensile strength. Strict quality inspection must be conducted on the welded seams, with commonly used testing methods including inflation and vacuum methods, to ensure that the seams are free of leakage. After the completion of the project, a comprehensive inspection of the entire impermeable system is required to ensure that the impermeable effect of the geomembrane meets the design requirements.
The impermeable geomembrane for reservoirs is easy to use and has a fast construction speed. It plays an active role in reservoirs and related water conservancy projects, providing a solid guarantee for the rational development and utilization of water resources.
