Underestimating the potential consequences of unresolved pinhole leaks in waterproofing membranes can be costly, resulting in significant damage to property if not addressed. Pinholes in a single ply membrane can develop over time to become significant breaches resulting in internal damage or leaks.
Therefore, it essential to identify these at the earliest opportunity, whether it be as part of an integrity test to newly installed waterproofing or part of an ongoing maintenance programme for an existing installation.
Attempts to establish the integrity of waterproofing membranes precisely with the naked eye can be time consuming and often proves to be fruitless when the puncture or pinhole is miniscule. Thornton Consulting provides an accurate and highly professional electronic leakdetection service to locate such pinholes for clients in the building and property sector throughout the UK.
Thornton Consulting were pioneers of Electronic Leak Detection and integrity testing of waterproofing membranes in the 1980’s, of which the pinhole test, also known as the “holiday” test forms a part. Since this time, we have built long-term working relationships with Main Contractors, Roofing Constructors and Material Manufacturers. Any existing issues can be identified and resolved avoiding further damage, with a pre-sign off inspection on new installations giving reassurance that the roof membrane is intact.
Pinhole (Holiday) leak detection is carried out with a phosphor bronze brush through which an electrical charge is passed. The brush is then swept across a dry roof surface, with an alarm indicating to the operator the exact location of the breach. Breaches can then be easily repaired by the roofer and retested to ensure the roof is watertight at completion of the test.
