Detection methods
How we find your water leak
Six non-invasive methods, run in sequence on every session.
Acoustic listening
Ground microphone and correlator setup on paving, slab and driveway seams. Pinpoints under-slab leaks within a metre 90% of the time.
Tracer gas
H₂/N₂ mix into the isolated pipe; a handheld sniffer follows the release plume back to the escape point above ground.
Moisture readings
Digital moisture meter across skirting boards, floor slabs and wall cavities to confirm interior migration paths.
Pressure testing
The pipe is isolated at the meter and pressure-held. Loss rate quantifies the leak; sequencing narrows the branch.
Thermal imaging
FLIR thermal camera on cold mornings identifies warm plumes above hot-water pinholes and radiant zones from slab leaks.
Photographic report
Insurance-approved report with numbered findings and GPS pinpoints — emailed within two business days.
