Electric field vector mapping leak detection.

We ve tested over 400 million square feet of membrane worldwide through overburden and ballast on horizontal and vertical surfaces providing perfectly accurate results. As a roofing contractor for 38 years we understand how critical accurate electronic leak detection is for our clients. Efvm is a low voltage leak test method that creates an electrical potential difference between a non conductive membrane surface and conductive structural deck or substrate which is earthed or grounded. Electric electronic field vector mapping.

Electric field vector mapping efvm efvm is a leak detection method based the measurement of the current flow between a non conductive membrane surface and a conductive substrate ie. Low voltage 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. A low voltage electrical current is used to create an electrical potential between a non conductive membrane and a grounded conductive deck or substrate. A thin film of water is applied to the surface to be.

Electric field vector mapping or efvm is a type of non destructive testing used to locate a breach or void in a waterproofing membrane. Leak detection efvm electric field vector mapping is the standard for waterproofing verification.

This mesh is a non corrosive material that prevents aging deterioration within the roofing system. Over the years we have used many forms of interpretive testing methods such as infrared thermography capacitance testing hygrometers vector mapping sampling etc and found them all to have too many limitations. Efvm electric field vector mapping technology is a standard option for testing and verifying system integrity on hyproof waterproofing systems. Ild is the world leader in electric field vector mapping efvm technology we created it.

Already europe s most widely used method for detecting roof leaks vector mapping is rapidly being adopted by manufacturers contractors and specifiers in the. Established in 2005 as one of the first electronic leak detection firms in the united states honza group inc. Efvm is unique in its ability to test the integrity of waterproofing membranes.
