Electronic Leak Detection (ELD) testing requires a conductive substrate directly under the membrane for a valid test. Whenever the substrate is to be non conductive such as coverboard, insulation, wood or light weight concrete, Detec’s TruGround Conductive Primer can be applied to enable electronic testing of the membrane.
Detec Systems is often asked how to confirm if the TruGround is continuous from board to board. We’ve developed a tool called the TruGround Continuity Tester (TCT) that will confirm continuity between seams.
