Electric Field Vector Mapping Testing

By performing both tests in this sequence we can test much larger areas in less time and test them much more effectively.

Electric field vector mapping testing.

Our patented technology zeroes in on leaks. 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. Truground is the best way to make sure the waterproof membrane on your conventional roof assembly is dry and watertight. Get full testability and full adhesion install the closest most complete grounding substrate for the entire membrane more.

However a commonly used unit in atomic physics and chemistry is the debye d. Electric field vector mapping efvm method. 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. Already europe s most widely used method for detecting roof leaks vector mapping is rapidly being adopted by manufacturers contractors and specifiers in the.

Developed by the ild team through years of research and field installation the vector mapping conductive mediums were created to test membranes or coatings over non conductive substrates. Efvm electric field vector mapping technology is a standard option for testing and verifying system integrity on hyproof waterproofing systems. This testing method adheres to the astm standard practice for detecting breaches in roofing and waterproofing membranes astm d8231 19. For use with both high and low voltage testing methods.

Advanced dual sensor cross scan technology developed in the usa in early 2000. 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. The electric dipole moment is a measure of the separation of positive and negative electrical charges within a system that is a measure of the system s overall polarity the si units for electric dipole moment are coulomb meter c m. Vector mapping electronic leak detection pinpoints breaches in roof and waterproofing.

A thin film of water is applied to the surface to be. What is electronic field vector mapping efvm. 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. 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.

As a roofing contractor for 38 years we understand how critical accurate electronic leak detection is for our clients. The lv vector mapping test finds less obvious anomalies such as debris under membrane edges cold joints open t seams migratory leaks etc.
