Leak Detection Technology Sydney from International Leak Detection

EFVM® provides an efficient and highly accurate leak detection solution.

The EFVM® leak detection system makes flood testing waterproofing membranes a thing of the past.

EFVM® is a low voltage test method that creates an electrical potential difference between a non-conductive membrane surface and a conductive substrate, which is earthed or grounded.

By applying water on the membrane surface and using the water as a conductive medium, an electric field is created and a breach in the membrane creates a vector (ground fault connection).

The EFVM® technician reads the electric flow travelling across the membrane mapping the breaches with pin point accuracy.

Advantages of the EFVM® testing system

Exact pinpointing of membrane breaches
Non-destructive to the membrane
Can be performed on sloped structural decks
Membrane defects can be repaired and retested without delay to the construction schedule
Limited use of water required for the EFVM® test
Eliminates unnecessary removal of the overburden to locate a membrane breach
Membrane performance can be monitored during its lifespan through the overburden
