HGI successfully uses the electrical resistivity method for leak detection of HDPE liners in ponds, landfills, and heap leach pads, whether bare, double- , or single-lined. The flexible geophysical survey design with resistivity mapping accommodates liners filled with consolidated rock, unconsolidated soils, or solutions with varying pH and conductivity.
