Continuously monitor long after the initial membrane installation.
Electric field vector mapping cost.
Efvm electric field vector mapping technology is a standard option for testing and verifying system integrity on hyproof waterproofing systems.
Even in the case of minimal contact with moisture the system closes the electrical circuit.
Truground is the best way to make sure the waterproof membrane on your conventional roof assembly is dry and watertight.
The vmg is installed below the roofing waterproofing membrane.
The lv vector mapping test finds less obvious anomalies such as debris under membrane edges cold joints open t seams migratory leaks etc.
Moisture penetration can be located quickly and cost effectively repaired.
Vector mapping grid vmg overview.
The vector 9 conductor wire on top of the membrane delivers direct current tension to the surface.
Detec s permascan system is the most advanced electronic leak detection technology for monitoring a roofing or waterproofing assembly.
A concrete rooftop balconies planter box etc which is earthed or grounded.
For use with both high and low voltage testing methods.
Vector mapping electronic leak detection pinpoints breaches in roof and waterproofing.
By performing both tests in this sequence we can test much larger areas in less time and test them much more effectively.
Repairs from the hv test are also retested during the vector mapping.
Low voltage vector mapping is a method of electronic leak detection that pinpoints breaches in the roof membrane by tracing the flow of an electric current across the membrane surface.
Efvm is becoming one of the most popular forms of quality control testing for architects specifiers contractors manufacturers and building owners across the united states.
What is electronic field vector mapping efvm.
The vmg is a specially selected stainless steel grid that serves as a patented conductive medium when used with roofing waterproofing systems that incorporate electric field vector mapping efvm leak detection systems.
Intended to be used in lieu of traditional flood testing efvm is provided by international leak detection an independent third party agency that will provide our customers with an unbiased.
Electric field vector mapping admin allwater 2017 11 28t09 41 24 00 00 electric field vector mapping efvm efvm is a leak detection method based the measurement of the current flow between a non conductive membrane surface and a conductive substrate ie.
Over the years we have used many forms of interpretive testing methods such as infrared thermography capacitance testing hygrometers vector mapping sampling etc and found them all to have too many limitations.
As a roofing contractor for 38 years we understand how critical accurate electronic leak detection is for our clients.
