Electric Field Vector Mapping

About Low Voltage Vector Mapping

Electric vector mapping is a cutting edge technology that is redefining the art of leak detection and quality assurance in low-slope roofing and waterproofing systems. Vector mapping is a method of electronic leak detection that pinpoints breaches in the roof membrane by tracing the flow of an electric current across the membrane surface. Already Europe’s most widely-used method for detecting roof leaks, vector mapping is rapidly being adopted by manufacturers, contractors, and specifiers in the United States.

Vector mapping eliminates the dangers and potential damage inherent in traditional flood testing. Unlike the interpretive process of water, flood, infrared, or nuclear testing, vector mapping detects membrane faults directly. It is ideal for quality and warranty assurance needs, for leak testing of green (vegetative) and ballasted roofs, and for leak detection in all low-slope roofing systems in which the membrane is not electrically conductive and the deck can be electrically grounded. Even pinhole leaks invisible to the naked eye can be pinpointed with vector mapping, and repairs can be made on the spot and immediately retested to ensure watertight results.
