Membrane Surface Integrity Testing from International Leak Detection

What is EFVM®?

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.

- 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

EFVM® is ideal for:

- Garden Roofs
- Roofs with ballast
- Roofs with paving stones
- Exposed membrane roofs
- Non-insulated and insulated roof systems
- Inverted roof systems
- Parking garages/Parking decks
- Pond/water container liners
- Swimming pools
