Electronic Leak Detection Across BC
Low-voltage ELD for commercial roof membranes and digital noise loggers for water distribution networks — precise breach location that complements thermal imaging and acoustic detection.
Electronic Detection Applications
Single-Ply Roof Membrane ELD
Low-voltage electrical field testing locates membrane breaches on TPO, EPDM and PVC roofs to within centimetres — more precise than thermal imaging for fully adhered membranes.
Digital Noise Loggers
Overnight acoustic noise loggers deployed at valve boxes and hydrant connections across a water distribution zone record pipe sound during minimum-demand hours — correlating to leak locations the next morning.
Correlation for Large Systems
Multi-point electronic correlators applied to complex water main networks locate leaks in pipes up to 400mm diameter.
Post-Repair ELD Verification
Electronic field testing after a membrane repair confirms the patch is fully sealed before the inspection report closes.

Frequently asked questions
How does ELD testing work on a roof membrane?
A low-voltage electrical potential is applied to the wet membrane surface. Where the membrane is intact, it acts as an insulator. Where there is a breach, current flows to the conductive roof deck below — detected by a sensor sweeping the membrane surface. The technology locates defects to within 30cm on a saturated membrane.
Does ELD testing work on all roof types?
ELD is most effective on fully adhered single-ply membranes (TPO, EPDM, PVC) with a conductive substrate. It is not applicable to aggregate-surfaced BUR or to membranes over non-conductive decks without a conductive underlayer. We assess your roof type before recommending ELD.
What are noise loggers and how do they find water main leaks?
Noise loggers are electronic devices placed at valve boxes and hydrant fittings overnight. They record pipe noise at hourly intervals during the period of lowest demand (typically 2–4 AM) when leak noise is clearest. The recorded data is downloaded and analysed to identify the network zone with the highest leak signal.
Is electronic detection used alongside other methods?
Yes. We typically combine ELD with thermal imaging for complete flat roof surveys — thermal identifies wet insulation zones and ELD precisely locates the membrane breach within those zones.
