Geomembrane Liner Installation

 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 areas of high current density near the leaks.

  The electrical leak location method is a powerful tool used to detect electrical paths through leaks in a geomembrane liner.Electrical measurements are then made on the soil or in the water to locate these points of current flow through the leaks. ASTM D6747 describes the various implementations of the method.Electrical leak location surveys are conducted on the primary or secondary geomembrane liners with water or soil covering the liner.
