Why Companies Choose Detec Australia Over Other Leak Detection Methods

IntegriScan is a point in time, quality control Electronic Leak Detection testing service that confirms the integrity of the waterproofing/roofing membrane installation

  • Test 100% of waterproofing/roofing membrane versus other "hunt and peck" methods
  • Reliably tests vertical surfaces
  • Wall junctions, perimeter details and membrane penetrations are easily tested
  • Tests up to 3,715 square meters per day
  • Detects hard to see breaches
  • Breach repairs can be re-tested the same day
  • Minimal setup time; No perimeter wire required; No need to isolate penetrations
  • Audio & visual components for easy and accurate breach location alerts
  • Tests conventional membranes with TruGround Conductive Primer directly under the membrane
  • Only the ELD method available for testing black EPDM and other semi-conductive membranes
  • Can be used for forensic testing of existing roofs
  • The most advanced, accurate, reliable, and cost effect Electonic leak detection method available
  • A superior alternative to flood testing
  • Meets ASTM D8231-19 ( Standard practice for Electronic Leak Methods for detecting and locating leaks )

Flood Testing

  • Meet Guide ASTM D 5877 for ELD Testing only. Does not meet current ASTM D8231 practice for ELD
  • No large volumes of water wasted
  • Speed of test. Flood testing generally takes days
  • Flood testing invariably doesn’t test to the entire substrate.
  • Doesn’t precisely locate defects
  • Possible structural loading stress

High Voltage Testing

High voltage was developed in Europe in the 1970s. This method works on horizontals as well as verticals but does not work on semiconductive membranes such as black EPDM.  The technician sweeps the metal brush over a completely dry membrane.

Any moisture present will create a false alarm.  The equipment releases up to 40,000 volts, and when it passes over a breach, a spark will be seen.  High Voltage is not the best for seam void detection as it requires a direct vertical air gap to spark.  The spark will not travel horizontally.

It also relies on the technician to calibrate the electronics for the micron thickness being tested.  If the electronics are set too low, breaches will be missed.  If calibrated too high, it can burn the membrane.

  • Meet Guide ASTM D 5877 for ELD Testing only. Does not meet current ASTM D8231practice for ELD.
  • Must be calibrated for membrane thickness. May cause damage or miss leaks if membrane thickness varies as with Liquid systems.
  • Must be performed in perfectly dry conditions
  • Cannot test semi-conductive membranes such as black EDPM or Butynol
  • Struggles to pick up seam breaches in sheet membranes

Vector Mapping

Low voltage vector mapping was also developed in Europe in the 1970s.  This method works on horizontal surfaces but is not feasible for verticals.  It also does not work on semiconductive membranes such as black EPDM. 

The technician sets up a perimeter wire to isolate the testing area.  All grounded objects within the testing area must be isolated. Otherwise, they will be detected as a breach. There must be a continuous water path touching the perimeter wire and every breach within the testing area. 

A gap in water coverage can result in missed breaches.  As the technician probes the area, the electronics point in the direction of a breach. Any breaches found must be isolated from the testing area; otherwise, they will continue to be detected.

  •  Meet Guide ASTM D 5877 for ELD Testing only. Does not meet current ASTM D8231 practice for ELD.
  • Requires Isolating the testing area and all grounded objects
  • Requires a continuous layer of water within the testing area
  • The breach must be isolated or immediately repaired when found.
  • Not feasible for testing vertical surfaces.
  • Cannot test semi-conductive membranes such as black EDPM or Butynol

Our Recent Projects

Detec Systems is reliably monitoring and testing all types of roofing and waterproofing assemblies

Faulkner Road Community Centre currently being built by PACT Construction required as per Architects specification provided by Bollig Architects to have the Soprema waterproof membranes fully tested by Detec Australia

City of Perth – Council House

Freyssinet were contracted to remove tiling, repair existing waterproof membrane on one half of the building which had been replaced 2 years earlier and install a new membrane system on the remaining half. Detec Australia was contracted to find the leaks in the first half and test the new membrane to ensure no leakage will occur.

Scarbough Pool Complex

Cooper and Oxley engaged Detec Australia to test the liquid membrane being installed on the carpark deck and terrace walkway and gardens with retail areas, changerooms etc directly below to ensure no leaks were found in the waterproof membrane.

Refurbishment with a new 2 layer Soprason 3-4 AR Torch on Membrane completed by SRG Global
