The Hunan Province landfill project covers an area of approximately 82,000 square meters. Technical personnel from Huabiao Guoxin Inspection conducted integrity tests on the geomembrane at the landfill. The landfill's slope employed the electric spark method, while the waste disposal area at the bottom used the double electrode detection method. Data analysis from the tests indicated that the impermeable system is in good condition, with no leakage points detected.
