EFVM® Leak Detection System from International Leak Detection![]() Electric Field Vector Mapping® Now available in Australia, the EFVM® leak detection system makes flood testing of waterproofing membranes a thing of the past. Initially introduced to the United States market in 2001, the EFVM® System is now used extensively around the world. Waterproofing membrane defects can occur during or after installation; e.g. mechanical damage caused by others, workmanship defects, material defects, design faults, weather related defects or membrane deterioration. EFVM® provides an efficient and highly accurate leak detection solution. What is EFVM EFVM® is a low voltage test method that creates an electrical potential difference between a nonconductive membrane surface and a conductive substrate, which is earthed or grounded. By applying water on the membrane surface and using the water as a conductive medium, an electric field is created and a breach in the membrane creates a vector (ground fault connection). The EFVM® technician reads the electric flow travelling across the membrane, mapping the breaches with pin point accuracy. Advantages of the EFVM testing system
Accurate pinpointing of membrane breaches
