|COMPARE||INTEGRISCAN™||Electric Field Vector Mapping (EFVM)|
Advanced dual sensor cross scan technology developed in the USA in early 2000. This testing method adheres to the ASTM standard practice for detecting breaches in roofing and waterproofing membranes (ASTM D8231-19).
Vector Mapping is a triangulation-based sampling technology developed in Germany in the early 1970’s with no advancements since.
IntegriScan utilizes a mobile platform that isolates a small test area for better conductance and more reliable readings.
A perimeter wire is installed to define an isolation area and then probing poles are used to sample the area within the isolation area. The results rely heavily on the technician’s experience.
100% of horizontal and vertical surfaces are able to be tested.
Testing is done via sampling, so actual coverage is indeterminate. This method can only visually inspect vertical surfaces. The test relies heavily on the technician’s experience.
|TEST INVERTED ASSEMBLIES|
YES, no limitations!
YES, but due to the large perimeter wire isolation area, a continuous water path can’t be verified which can result in missed breaches.
|TEST CONVENTIONAL ASSEMBLIES|
YES, with TruGround® on new assemblies.
EFVM may work with a properly placed conductive medium directly under the membrane on conventional assemblies.
|TEST BLACK EPDM||YES – ONLY Detec Systems can test black EPDM and semi conductive cold fluid applied waterproofings.||NO – Can only test non conductive waterproofing and roofing membranes.|
|TEST VERTICAL SURFACES||YES – Detec’s Vertical Scan Unit (VSU) is a belt mounted roller apparatus that will detect breaches in verticals.||NO – Vector mapping would have to set up a vertical perimeter wire and have a continuous layer of water which is not feasible.|
|SQUARE FOOTAGE PER DAY||FASTEST – Up to 40,000 sq ft/day for horizontals and up to 10,000 sq ft/day for verticals.||MODERATE – Can take hours or days to set up the perimeter wire. Can possibly test up to 20,000 sq ft/day for horizontals.|
Virtually no chance for false positives or complete misses. Wall junctions, perimeter details, and membrane penetrations are tested electronically.
Vector Mapping has a high potential for false positives and complete misses. Wall junctions, perimeter details, and membrane penetrations can only be visually inspected.
