Use the water gun method to locate the electrical leakage of the exposed geomembrane
Water gun method-This technology is suitable for dry uncovered geomembrane placed directly on a fully conductive layer under the electrically insulating geomembrane. In order for this technology to effectively locate the leak, the flowing water must contact the conductive material under the geomembrane through the leak point, thus completing a closed circuit. The detector is used to monitor the current or voltage changes between two points along the spray gun column. Whether there is a leak. This method can usually locate leaks as small as 1 mm in diameter.
