ASTM D7240

The electrical leak location method is a powerful tool used to detect electrical paths through leaks in a geomembrane liner. A voltage is applied to an electrode placed in the soil or water covering the liner and to an electrode placed in the leak detection zone for double-lined systems or connected to earth ground for single-lined systems. Because the geomembrane liner is an electrical insulator, current will flow only through leaks in the liner. This current produces localized anomalous…
