Our Leak Detection Technology & Methods

Roof, slab and underground leaks are tricky to trace. We use a combination of professional diagnostic tools to pinpoint the exact source without damaging your property.

CCTV drain cameras to inspect internal water paths
Acoustic leak detection for leaks behind walls and under slabs
Thermal imaging to spot hidden moisture in walls and ceilings
High-pressure jet blasting when blockages or roots are involved
Pressure testing to confirm leak locations and damage extent

Combining these tools delivers the most accurate, non-destructive leak detection possible - saving you money in the long run.
