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. EFVM® is unique in its ability to test the integrity of waterproofing membranes with overburden or ballast. This non-destructive method is important for green roofing systems because the EFVM® test can read through the overburden and ballast, while still providing perfectly accurate results.
Our certified inspectors perform non-destructive integrity tests on new or existing waterproofing membranes and containment liners using our pinpoint-accurate EFVM® technology. This rigorous technology, combined with our multilateral services, provides superior detection of all waterproofing defects and breaches.
The smallest puncture, membrane split, or mechanical default can cause severe and costly structural decay, interior damage, wet insulation, and mold. Only ILD® can offer proven expertise and our advanced EFVM® proprietary technology for unparalleled leak detection.
