Roof Vector Mapping

A grid can be permanently installed to facilitate future testing if the overburden protection layer does not have electrically resistant properties.

Roof vector mapping.

One lead from a pulse generator is connected to this wire loop perimeter. Experience has shown that the best way to provide efficient and budget wise testing is to perform a high voltage sweep on the entire roofing assembly then perform low voltage vector mapping. This completes the circuit between the. Our vector mapping technicians can help you troubleshoot the toughest waterproofing problems in virtually any application with high or low voltage leak detection technology.

Vector mapping pinpoints breaches in the roof membrane by tracing the flow of an electric current across the mem brane surface. Vector mapping is designed for on demand use in new and existing roofing and waterproofing membrane systems. Electronic field vector mapping is becoming one of the most popular forms of quality control testing for architects contractors and building owners. 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.

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. As the technician sweeps the brush electrode over the surface of the roof membrane electricity will flow through any breach in the membrane.
