Without breaking · Insurance compatible
Four combined technologies — tracer gas, geophone, FLIR thermal camera and acoustic correlator — to locate the leak without breaking. If we do open, we open only the exact point. If we don't find it, you don't pay.
Verifiable signs of a leak
You don't need to wait for a damp patch on the ceiling. These signs are objective indicators, ranked from "very likely" to "almost certain":
Why you should not break the floor blindly
The temptation is understandable: "let's break the bathroom floor and see what we find." The problem:
That is why we invest in four non-destructive detection technologies. A full inspection costs less than a single botched opening.
Our 4 technologies
No single technique solves every case. The difference between finding a leak in 1 hour or never finding it lies in knowing which to use and combining them in the right order.
We inject the mixture into the empty pipe and the hydrogen escapes through the leak. An electronic surface sensor detects it with centimetre precision. Non-flammable at this concentration, does not contaminate, leaves no residue.
Use case: pipes hidden in walls or under screed, unpressurised.
Amplifies the sound of water escaping under pressure from a buried metal pipe. The operator sweeps the surface with the sensor and triangulates the point of maximum acoustic intensity.
Use case: buried pipes in gardens, courtyards or car parks.
Detects temperature differences. A hot or cold water leak creates a thermal pattern visible on screen. Useful for tracing the path and exit point without touching anything.
Use case: underfloor heating, walls, false ceilings.
Two digital sensors placed at accessible points on the network. The processor calculates the time difference between the acoustic signal reaching each one and triangulates the source with centimetre precision. Ideal for very slow drips.
Use case: small drips, long networks, buried sections.
Compatible with your home insurance
We don't just locate the leak: we issue a technical report with a code that your insurer accepts directly. You don't have to argue with the loss adjuster or pay more than your excess upfront.

The FLIR thermography identified an anomalous thermal pattern beneath the hallway tiles. A 20×20 cm pinpoint opening, sleeve welded, closed. A single tile replaced. Total cost, detection plus repair: €340. Mapfre insurance covered the detection.
A digital geophone triangulating from 3 accessible points located the leak in a PE pipe at 1.80 m depth, below the solarium. A surgical 60×60 cm opening in a single removable slab tile. Resolved without closing the pool.
A pipe dripping at 1 mL/min — inaudible to the human ear. The 2-point acoustic correlator detected the signal time difference and pinpointed the source at 4.2 m from the meter cupboard. Matched an exposed elbow in the garage false ceiling.
Client had damp on a party wall. The neighbour denied any leak. Tracer gas injected into each connection — the sensor detected hydrogen coming from the neighbour's wall. The technical report enabled the community to assign liability without going to court.
Cost · Honest policy
It makes no sense to charge for an hour of inspection if we haven't solved anything. We accept that as an occupational risk. In 20 years we've applied it twice — both were external leaks from the municipal network, not our responsibility.
What's included: inspection with all 4 technologies as needed, identification of the exact point and a technical report with a code for your insurer.
If we don't find the leak: nothing is charged. Zero.
If repair is needed afterwards: a fixed written quote before we touch the screed. You decide whether we proceed.
Frequently asked questions
Full inspection: €180–280 depending on complexity. If we don't find the leak after the inspection, nothing is charged.
Between 1 and 3 hours. A kitchen leak is usually resolved in 1 hour. A leak in underfloor heating or a downpipe can take 2–3 hours.
Ideally not. That is exactly why we use tracer gas, geophone, thermography and correlator. If opening is needed afterwards, we open only the exact point — not the whole room.
If you have a home insurance policy with leak coverage, 95% of policies cover detection. We issue a technical report with a code that your loss adjuster accepts directly.

We inject a mixture of 95% nitrogen and 5% hydrogen into the empty pipe. The hydrogen escapes through the leak and an electronic surface sensor detects it. Non-flammable at this concentration, no residue.
It detects temperature differences. A hot or cold water leak creates a thermal pattern that the FLIR identifies in seconds. Very useful for underfloor heating and walls.
For pressurised leaks in buried metal pipes. It amplifies the sound of escaping water, audible from several metres away.
The four technologies complement each other. For slow drips we use a two-point digital acoustic correlator that triangulates the source with centimetre accuracy.
Yes. Specific technique using dye, circuit pressure and thermography of the pool shell.
Yes. We coordinate with the hotel maintenance team to work floor by floor without cutting the main water supply.
No. We work room by room with protective covers in place.
