- How to challenge a freeholder who says no leak was found A freeholder's verbal or informal claim that no leak exists does not close the matter, a leaseholder can commission an independent leak detection survey to produce documented, method-specific evidence that either confirms or disputes that position. ADI Leak Detection carries out non-invasive surveys using acoustic listening equipment, thermal imaging and tracer gas testing to locate hidden water leaks beneath floors, behind walls and within shared building fabric.
- Pinpointing a burst water main under your property Acoustic leak detection locates hidden water leaks in pressurised mains by picking up the sound energy a leak produces as water escapes under pressure through a pipe wall. ADI Leak Detection uses specialist acoustic listening equipment to trace that sound along the pipe and pinpoint the breach before any excavation begins. ADI's engineers apply acoustic ground microphones and listening rods to identify where leak noise is strongest, narrowing the position down to a precise point. The episode covers how pressure affects leak sound, what acoustic listening devices detect, how ADI engineers work along a pipe run to confirm the leak location, and why non-invasive detection reduces unnecessary digging.
- When does acoustic detection work best for finding a hidden water leak? Acoustic leak detection works best on pressurised supply pipes running beneath solid floors, behind walls, or under driveways, where water escaping under pressure creates vibration that travels through the surrounding material. ADI Leak Detection uses acoustic listening equipment to trace these vibrations back to their source, pinpointing the breach without unnecessary excavation.
- Can a survey tell if water damage behind rendered walls is old or new? Water damage found behind rendered walls during renovation can be active or historic, and a specialist survey distinguishes between the two by measuring residual moisture levels, mapping damp patterns and assessing whether a live water source is still feeding the affected area. ADI Leak Detection uses thermal imaging, acoustic listening equipment and moisture profiling to determine whether a leak behind a rendered wall is ongoing or has already dried out.
- How to tell if water damage behind a wall is live or old Water damage found during a strip-out can come from an active leak still running or from a historic one that dried out long ago, and telling the difference matters before any repair or reinstatement work begins. ADI Leak Detection uses moisture meters, thermal imaging and tracer gas testing to determine whether water is still escaping into a wall void or whether the dampness is residual.
- Finding a leaking pipe you can't see or reach Acoustic leak detection finds hidden pipe leaks by picking up the sound and vibration that escaping water creates in the pipe wall and surrounding ground, even under concrete floors or behind solid walls. ADI Leak Detection uses acoustic listening equipment to trace that sound signature to its precise source, avoiding unnecessary excavation.
- Waterlogged ground – will leak detection still work on a water main? Waterlogged ground does not make acoustic leak detection impossible, but it does reduce the clarity of sound signals travelling up through saturated soil, which means ADI Leak Detection engineers adapt their method and interpret results differently than they would on dry ground. ADI Leak Detection uses acoustic listening equipment to trace escaping water along supply pipework even where ground conditions are already wet.
- What happens inside a pressurised pipe when it starts to leak?

- What does a leak detection specialist do when a leak cannot be reached When a water leak cannot be directly accessed, ADI Leak Detection uses non-invasive methods including acoustic listening equipment and tracer gas to trace the leak path and pinpoint the exact breach without opening up floors or walls unnecessarily. ADI Leak Detection applies these techniques to locate hidden water leaks beneath solid floors, behind tiled surfaces and under concrete foundations in residential properties.
- Tracer gas or acoustic: which method suits your social housing leak? Acoustic leak detection listens for the sound a pressurised pipe makes when water escapes through a breach, while tracer gas detection introduces a safe hydrogen and nitrogen mixture into the pipework and traces where it surfaces through the ground or structure. ADI Leak Detection uses both methods on social housing properties, selecting the right approach based on floor construction, pipe depth and access constraints.
- How does tracer gas leak detection work in social housing? Tracer gas leak detection works by filling a pipe with a harmless hydrogen and nitrogen mixture, then using a sensitive detector to trace exactly where the gas escapes through a crack or joint, pinpointing a hidden water leak without opening up large areas of floor or wall. ADI Leak Detection uses tracer gas to locate water leaks in occupied social housing properties, keeping disruption to residents to a minimum.
- How does a ground microphone detect a buried water leak? A ground microphone detects a buried water leak by picking up the vibration that escaping water creates as it forces through a crack or joint in the pipe and radiates outward through the surrounding soil or structure. ADI Leak Detection uses ground microphones alongside acoustic correlators to trace and pinpoint hidden water leaks beneath driveways, gardens, and concrete floors without excavation.
- Water escaping from your land but no visible pipe damage A spinning water meter or unexplained damp patch on private land often traces back to a pressurised pipe defect, and acoustic leak detection locates that defect by listening for the distinct sound signature escaping water produces as it forces through a breach under pressure. ADI Leak Detection uses acoustic equipment to trace that sound along buried pipework, pinpointing the defect without excavation.
- Can acoustic leak detection find leaks in plastic pipes? Acoustic leak detection works on plastic pipes, though the signal behaves differently than it does on metal pipework.

- Why combine acoustic detection and thermal imaging for damp investigations? Using acoustic detection alongside thermal imaging gives engineers two independent lines of evidence, acoustic equipment pinpoints where water is escaping through pipework noise, while thermal imaging reveals the full extent of moisture spread through temperature contrast. ADI Leak Detection uses both methods together on damp investigations to avoid misdiagnosis and unnecessary damage to floors, walls and ceilings.
- Can leak detection tell if damp is from a cold or heating pipe? Acoustic leak detection can identify whether damp is caused by a cold water supply pipe or a central heating pipe, and ADI Leak Detection uses a combination of acoustic listening equipment, thermal imaging, and tracer gas to trace the source before any floor or wall is opened up. The two pipe systems run at different pressures and temperatures, which gives engineers measurable differences to work with.
