Electronic Leak Detector
Electronic Leak Detection (ELD) is the top choice for waterproofing integrity testing. It’s faster, safer, and more cost-effective than traditional flood tests.
High Voltage Electronic Leak Detection is a sophisticated method used to locate leaks in roofing membranes without the risks that come with flood testing a roof. It is particularly effective for detecting even the smallest breaches in non-conductive roofing and waterproofing membranes such as single-ply membranes, modified bitumen, and other types of waterproofing layers.
