Abstract
The present invention is a leak detection and location system that includes a waterproofing membrane; an underlayment disposed directly below the waterproofing membrane, wherein the underlayment is non-conductive and will become conductive only when saturated; a conductive layer disposed below the underlayment; a voltage source attached to the upper side of the waterproofing membrane and the lower side of the underlayment; a test set with two handheld poles and an indicator that indicates a difference between voltages detected by the handheld poles; and a device that creates an electrical field across the waterproofing membrane.
