The Erdos Chemical Industrial Park Reservoir Project in Inner Mongolia utilizes a two-bag-one-membrane anti-seepage structure. After the anti-seepage material construction is completed, an integrity test of the anti-seepage area is conducted using the double-electrode testing method. During the testing, five leakage points were found. On-site repairs were made to the geotextile leakage points, and the re-testing passed after the repairs.
