Leak Investigations

We pride ourselves on always identifying the exact point(s) of water ingress. Our investigations cover all areas, not just the roof.

Aided with the latest technology in electronic leak detection, we are able locate the exact point(s) of water ingress, which may not necessarily be coming from the roof. A full report of our findings is provided.

Thermal imaging and Moisture Mapping

We can analyse the roof and produce a detailed thermal image map indicating the location of trapped moisture within the roof build-up, floors and walls of the building using moisture meters and infrared cameras

Electronic Leak Detection

Electronic Leak Detection (ELD) tests are a non-destructive method of locating pinhole leaks in a roof’s waterproofing membrane.

Any defects within the waterproofing membrane are identified with pinpoint accuracy, providing targeted and effective repairs to that of complete roof replacement.
There are two types of ELD tests. The dry and wet test.
The dry test is ideal for use on any flat or low-pitched roof. As the name suggests, this type of test can only be performed in dry conditions.
The operator paces the entire surface of the roof using a phosphor-bronze brush which delivers a stabilised D.C. output voltage across the membrane.
If any breaches are identified, the operator is alerted by an audible tone and a visual spark from the brush and the surface is marked for repair.
The wet test method is ideal for use on any flat or low-pitched roof to identify imperfections in exposed membrane or ballasted systems.
This test is performed in wet conditions (rainfall) or the tested area is hosed down prior to conducting the test.
A generator pulses a 40V voltage which is conducted onto the roof build-up via a wire ring circuit.
As most membranes used for waterproofing are more or less non-conductive, the pulse from the generator chooses a path across the moisture to where the leak is located, flowing over the damp surface in all directions to reach the perimeter ring circuit.
This allows the operator to determine the direction of the flow and trace it back to its source.
This will be the exact spot where moisture is penetrating the roof membrane and the surface is marked for repair
