Abstract
A conductive geotextile for use in a leak detection system is disclosed. The conductive geotextile has a flexible substrate with a first face and a second face and a polymer layer laminated to the substrate. The polymer layer may be equal to or less than 0.006 inches thick and has a first face and a second face, with the second face adjacent to the first face of the substrate. The polymer layer has a conductive thin film coextruded onto a core, with the conductive film being at the first face of the polymer layer. The conductive thin film may be equal to or less than 0.003 inches thick and has a surface resistivity equal to or less than 4000 ohm per square.
