As the technician sweeps the brush electrode over the surface of the roof membrane electricity will flow through any breach in the membrane.
Roof vector mapping.
Low voltage vector mapping.
Nationwide since 1984 electronic vector mapping is a cutting edge technology that is redefin ing the art of leak detection and quality assurance in low slope roofing and waterproofing systems.
A conductive wire loop is laid on the membrane around a section of the area to be tested.
Electronic field vector mapping is becoming one of the most popular forms of quality control testing for architects contractors and building owners.
Vector mapping is designed for on demand use in new and existing roofing and waterproofing membrane systems.
Vector mapping pinpoints breaches in the roof membrane by tracing the flow of an electric current across the mem brane surface.
By performing the hv test first we find most or all of the puncture type anomalies which may or may not be evident to the naked eye.
In low voltage vector mapping the surface of the roof membrane is moistened not flooded to create an electrically conductive medium.
One lead from a pulse generator is connected to this wire loop perimeter.
This completes the circuit between the.
