Leak Location Services


 For the wading survey mode the survey personnel wade in the water and systematically scan the submerged liner to locate any leaks. For this method, a water depth of between six and 30 inches (150 and 750 mm) is required. Temporary survey lanes are established across the bottom and are scanned with overlapping coverage. The liner field seams that can be located are double-checked. When detected, leaks are located to within one inch (25 mm) or less and immediately marked. The side slopes can be surveyed with deeper water using a long probe that is systematically scanned along the side slopes.

  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.
