Abstract
A membraneis a geomembrane, which takes the form of a non-conductive sheet. A conductive layeris printed on to the sheet, in this instance in a geometric pattern of a rectangular grid. The lines of the gridare conductive and connected to each other, with non-conductive gapsdisposed between the grid lines. Accordingly, a conductive linear network is formed, which has the requisite conductivity for leak detection.
