Electronic Leak Detection
Electronic leak testing isΒ a method used to detect leaks in various types of waterproof membranes, often used on flat roofs.Β It involves applying a low-voltage electrical current to the roof surface, and the current will flow towards areas of moisture due to water's conductivity.Β By identifying where the current is flowing, the location of leaks can be pinpointed, even pinhole leaks.Β This method is non-destructive, meaning it doesn't damage the membrane being tested.
How Electronic Leak Detection Works
Electronic leak detection begins with careful preparation, where the roof surface is cleared of any debris to create the best possible environment for testing. Once the area is clean, a low-voltage electrical current is applied across the roof membrane. This current naturally moves toward any areas where moisture is present or where the membrane has been compromised, as these act as conductors.
Using specialised detection equipment, technicians can then accurately locate the path of the current and identify the precise point of the leak. Once found, these areas are clearly marked on the roof, ready for targeted repair.
Benefits of Electronic Leak Detection
Electronic leak detection offers several important advantages. It is highly accurate, capable of pinpointing even the smallest leaks without causing any damage to the roof surface. The process is quick and efficient, saving time and reducing disruption. Its cost-effectiveness lies in its ability to catch problems early, preventing more serious and expensive water damage later on.
This method is also extremely versatile and can be used on a variety of roof types, including flat and inverted roofs, and works in both dry and wet conditions.
