EVA waterproofing membrane for water reservoir
The core functions of waterproofing membranes include:
1. Seepage prevention and isolation: Used in engineering projects such as earth-rock dams, canals, and liquid storage tanks to prevent water leakage.
2. Protection and reinforcement: Provide structural strengthening in subway systems and tunnel linings.
3. Environmental protection and corrosion resistance: Widely applied in pollution control projects such as chemical plants, mining wastewater ponds, and waste disposal sites.
EVA waterproofing membrane for water reservoir
Geosynthetic clay liner (GCL) is a waterproofing and anti-seepage material made primarily from polymer-based synthetic resins. It effectively prevents liquid leakage and inhibits gas emission, and is widely used in construction, transportation, subway systems, tunnels, and hydraulic engineering projects. Featuring high tensile strength, corrosion resistance, anti-aging properties, and excellent impermeability, it is suitable for various applications such as water storage tanks, sewage ponds, artificial lakes, and landfill sites.

1. Seepage prevention and isolation: Used in engineering projects such as earth-rock dams, canals, and liquid storage tanks to prevent water leakage.
2. Protection and reinforcement: Provide structural strengthening in subway systems and tunnel linings.
3. Environmental protection and corrosion resistance: Widely applied in pollution control projects such as chemical plants, mining wastewater ponds, and waste disposal sites.
II. Typical Applications in Water Reservoirs
EVA waterproofing membrane is the core material of water reservoir anti-seepage systems and is commonly used in the following types:
1. Drinking Water Reservoirs: Food-grade EVA material is selected to ensure water quality is not contaminated, complying with the "Hygienic Safety Evaluation Specifications for Equipment and Devices for Domestic Drinking Water Supply and Distribution."
2. Industrial Water Reservoirs: Used for storing cooling water, process water, etc., with resistance to chemical medium corrosion.
3. Agricultural Irrigation Reservoirs: Prevents water seepage and loss, improving water resource utilization efficiency.
4. Firefighting Water Reservoirs: Ensures long-term water storage without leakage, providing reliable water supply when needed.
During construction, EVA waterproofing membranes are typically laid on the reservoir bottom and sidewalls, forming a continuous, seamless waterproof layer through hot-air welding. They are often used in combination with geotextiles to enhance protective and drainage functions.
