Hearing the leak others can't
Water escaping under pressure makes a distinct sound as it leaves a pipe and travels through the surrounding material. Acoustic leak detection uses highly sensitive ground microphones and correlators to pick up that sound and pinpoint where it is loudest, which is the leak itself.
It is the method of choice for underground water leaks and mains water leaks across Cornwall, where there is nothing to see on the surface. We often pair it with tracer gas and thermal imaging to confirm the source. Used with correlation, where sensors at two points calculate the exact position along the pipe, it locates leaks to within centimetres, so any excavation is minimal and precise. If you are new to how leaks behave, our Water Leak Guide is a useful starting point.
Why pinpointing beats opening up
Opening up walls and floors to chase a leak is messy and expensive, and it often misses. Acoustic detection finds the leak by sound first, so the disruption is kept to a minimum.
Pinpointing the leak before any access work means:
- the exact spot is found, not just a rough area
- floors, walls and ground are disturbed as little as possible
- the repair is smaller, quicker and cheaper to put right
- you are not paying to open up the wrong place
We listen for the leak with sensitive ground microphones and correlators, then mark the precise point for repair.
Where acoustic detection works best
Underground mains and supply-pipe leaks under gardens, drives and lanes
Buried leaks beneath concrete, tarmac and solid floors
Pressurised pipework where a leak is audible but hidden
Confirming and pinpointing a leak first found by thermal imaging

Acoustic leak detection FAQs
With correlation it can locate a leak to within centimetres along a pipe run, which means any excavation is small and targeted rather than exploratory.
Yes. The sound of escaping water carries through solid surfaces, so ground microphones and correlators can pinpoint leaks beneath driveways, patios and floors without breaking them up to look.
