The Xinjiang Changji City smelting plant's regulating pond project, covering an area of 37,000 square meters, utilizes a 2.0mm single-layer geotextile membrane for waterproofing. After the installation and welding of the waterproofing membrane, a leakage detection was conducted using the electric-heat method. No leakage points were found during the process, and the waterproofing construction section successfully passed the acceptance inspection.
