The project consists of three wastewater collection tanks with a total area of 500,000 square meters. The area where the project is located has low temperature, strong illumination and large temperature difference between day and night, which requires high performance of waterproof materials, needs to meet the requirements of aging resistance, high and low temperature resistance, environmental protection and corrosion resistance.
The tank bottom and wall utilized the direct spraying technology, and no leakage has occurred since it was completed in 2014.
