Geomembrane Weld Quality Inspection

Geomembrane on-site inspection method 1. Air inflation method   Geomembrane welding is double strips, with a cavity of about 10mm left between the two strips. Seal both ends of the section to be tested, insert an air needle. Inflate to 0.15MPa～0.20MPa, observe the vacuum gauge for 5 minutes. If the air pressure does not drop, it indicates no leakage and the weld is qualified. Otherwise, ...
