Sichuan Mianyang's certain pesticide company's soil and ecological restoration project covers an area of 330,000 square meters. The anti-seepage system consists of a single-layer 2.0mm geotextile membrane. It is covered with 80mm of planting soil, and the integrity of the anti-seepage membrane was tested post-application, showing good results. Three areas of mechanical damage were identified, which were subsequently repaired, and the anti-seepage membrane leaks were corrected after re-testing.
