ELECTRONIC LEAK DETECTION
Electronic Leak Detection (ELD) is a method of finding leaks in roofs, walls, and floors using electrical conductivity. The process involves using a low-voltage electrical current to locate breaches in the waterproofing membrane or coating. ELD is commonly used on flat roofs, where water can easily pond and penetrate through any vulnerable points.
How Electronic Leak Detection Works
Depending on the system, a conductive primer may be required, and will first be applied under the membrane.
The area is watered down.
A technician with a handheld electronic scanner attached to a grounding cable scans the membrane in search of breaches.
A breach is identified by detecting a water path to the building ground which completes an electrical circuit.
When the scanner crosses a breach, the electronics on the scanner will make both an audible and visual notification.
ADVANTAGES OF ELECTRONIC LEAK DETECTION
-
Immediate identification of breaches leading to potential water intrusion in roofing, waterproofing, or coating membranes.
-
Breaches can be repaired and retested the same day.
-
Reduction of potential or further water damage due to immediate identification.
-
Rapid inspections compared to traditional flood testing which could cause interior damage and per ASTM standards require 48 hours minimum time period
-
Conductive primer applied is approved for use on various systems from different types of non-conductive roofing, waterproofing, and coating manufacturers. It will not void manufacturers’ warranties.
