Leak Detection

High Voltage Electronic Leak Detection (HVELD) is a method of detecting breaches in waterproofing membranes and coatings. HVELD testing is performed using a high voltage current on a dry horizontal or vertical surface. A current is generated that will pass through a non-conductive material, such as a waterproof membrane, and should a breach be present, it forms a circuit sounding an alarm on the testing unit and pinpointing the exact location of the breach.

Advantages of HVELD testing:

  • detecting holes in membranes and coatings that are not visible to the eye
  • non-destructive
  • good for very small areas and difficult to reach areas or areas where flood testing is not possible
  • locates defects precisely and enables immediate repair
  • able to re-test repairs immediately, depending on the type of membrane
  • less expensive and less time consuming than conventional flood testing
  • eliminates the hazard of overloading structural decks during flood testing.

We can locate leaks on the following horizontal and vertical surfaces:

  • Torch-On Membrane systems
  • Liquid Applied Systems, such as acrylics and polyurethanes
  • Bituminous coatings
  • PVC membranes
  • TPO membranes
  • Butynol
