Electric Field Vector Mapping Cost

Truground is the best way to make sure the waterproof membrane on your conventional roof assembly is dry and watertight.

Electric field vector mapping cost.

Even in the case of minimal contact with moisture the system closes the electrical circuit. 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. The vector 9 conductor wire on top of the membrane delivers direct current tension to the surface. As a roofing contractor for 38 years we understand how critical accurate electronic leak detection is for our clients.

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 electric field vector mapping technology is a standard option for testing and verifying system integrity on hyproof waterproofing systems. Already europe s most widely used method for detecting roof leaks vector mapping is rapidly being adopted by manufacturers contractors and specifiers in the. Detec s permascan system is the most advanced electronic leak detection technology for monitoring a roofing or waterproofing assembly.

Continuously monitor long after the initial membrane installation. The lv vector mapping test finds less obvious anomalies such as debris under membrane edges cold joints open t seams migratory leaks etc. For use with both high and low voltage testing methods. Repairs from the hv test are also retested during the vector mapping.

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. Vector mapping grid vmg overview. Permascan permanently embedded fully automated breach detection and moisture monitoring systems. By performing both tests in this sequence we can test much larger areas in less time and test them much more effectively.

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. What is electronic field vector mapping efvm. Get full testability and full adhesion install the closest most complete grounding substrate for the entire membrane more. A concrete rooftop balconies planter box etc which is earthed or grounded.

Moisture penetration can be located quickly and cost effectively repaired. 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.
