Patent ID: 8566051

Claim:
A system for detecting and locating leaks in roofing and waterproofing membranes comprising: a detector array comprising a boundary wire loop and a plurality of sensors, wherein said boundary wire loop surrounds an area on top of the membrane to be tested for leaks and wherein said sensors are positioned at predetermined locations within said area to be tested; a signal generator in electrical communication with said boundary wire loop, wherein said signal generator applies voltage to said boundary wire loop; and a first computer in electrical communication with said boundary wire loop, said sensors, and said signal generator, said first computer comprising a processor, a memory, and a software product for detecting and locating leaks, wherein said software product is stored in said memory and executable by said processor; wherein said boundary wire loop creates an electrical field within an area defined by the boundary wire loop, wherein each of said plurality of sensors measures a voltage at a location of each sensor and communicates said voltage to said first computer, and wherein said first software product analyzes differences in voltage between adjacent sensors and any change in voltage in a single sensor from a prior test result stored in memory to detect and determine a location of a leak.
