Leak Detection: Finding and Rehabilitating Leaks
From Root Cause Analysis to Rehabilitation
A water stain on the wall, high water consumption, or a mold smell are typical signs of a leaking pipe. The actual leak is often invisible, but its potential consequences for your building are not. The biggest concern is usually not the repair itself, but the fear of torn-open walls and a destructive search for the cause. This is exactly where we come in.
Using state-of-the-art analysis technology, we track down the cause precisely, pinpointing the location, and in most cases completely non-destructively. But our service doesn't end with detection: As your partner and full-service provider, we prepare a clear report for your insurance company and directly offer the suitable rehabilitation solution.
Frequently asked questions about leak detection
Here you will find answers to the most common questions about leak detection.
Our process is clear and transparent. First, our experts will discuss the signs of damage with you. They then systematically narrow down the cause using the latest, non-destructive measurement methods. As soon as the leak is precisely located, we will provide you with complete documentation, which you can also use for your insurance company.
We use a range of cutting-edge, non-destructive processes. Depending on the situation, we use, for example, visual pipe inspection with channel TV, luminate testing when moisture enters the masonry, or intoxication to detect leaks and faulty connections.
The duration depends on the complexity of the case. A leak can often be precisely located within just a few hours. Our goal is always to work as quickly and efficiently as possible to find the cause and minimize subsequent damage for you.
The costs of professional leak detection depend on the effort involved. To give you a non-binding initial orientation, the price range for a typical bet is usually between 500€ and 2,000€.
Our process is absolutely transparent for you: We can often make an initial assessment of the likely cause based on your description over the phone or photos you have sent us. On site, our technicians will finally analyse the problem and discuss the necessary steps with you before we start.
Good to know: In most cases, the costs of leak detection are covered by building or household insurance. However, exceptions may be damage caused by the roof, for example. In any case, we will provide you with a detailed invoice for smooth processing.
After successful location, our service does not end. You will receive a detailed report from us that documents the damage in detail. As a full-service provider, we can also provide you directly with a professional offer for the necessary pipe or sewer rehabilitation on this basis. This gives you analysis and solutions from a single source.
Yes, the costs of leak detection are usually covered by your building or household insurance, as they are used to investigate the causes of damage. We recommend a brief clarification with your insurer and provide you with a detailed invoice that you need to settle the claim.

An overview of our leak detection methods
In order to find the cause of a leak beyond doubt, we use the latest analysis technology. Depending on your requirements, we combine various processes to provide you with a precise and clear result.
CCTV pipe inspection
At the CCTV & pipe inspection The condition of the pipe system is analysed non-destructively and damage is precisely located. The lines are traveled with a self-propelled, high-resolution swivel head and axial camera. All defects and events are documented exactly in accordance with the applicable standards (ATV, ISYbau or EN standard). The result is a seamless TV protocol with a clear plan outline as a reliable basis for decision-making.
Overview of features:
- Range of use: Precise condition analysis and pinpoint location of damage, cracks, deposits or leaks.
- main advantage: A non-destructive, visual inspection that provides complete and standard-compliant documentation as a basis for restructuring decisions.
- Technical details: Suitable for pipes from 30 to 1600 mm in diameter; use of high-resolution swivel head and axial cameras.
Luminate examination
Luminate testing is used to find the exact cause of moisture ingress into buildings. In this case, a pigment dispersion is introduced as a contrast agent into water-carrying pipes or sealing layers. In this way, even the smallest leaks can be located in order to be able to effectively remedy the problem.
Overview of features:
- Range of use: Determining the cause of moisture ingress on buildings (e.g. damp walls, ceilings).
- main advantage: Exact location and analysis of the cause of damage for targeted remediation.
- Technical details: Geotechnical process with injection of pigment dispersion (contrast agent).
Intoxication (fog process)
Intoxication is used to find leaks, faulty connections and foreign water ingress in a sewer system. This involves directing artificial fog into the sewer system. The fog visibly emerges from leaks and thus also detects “dead” connections or the causes of foreign water ingress (infiltration/exfiltration).
Overview of features:
- Range of use: Detecting leaks, faulty (“dead”) connections and foreign water ingress.
- main advantage: Makes system errors visible that are not always detectable through a purely visual TV inspection.
- Technical details: Introduction of artificial fog that is harmless to humans and the environment into the sewer system.
Further sewer investigation & documentation procedures
Tightness test
The leak test in accordance with ÖNORM B2503 is the official proof that your drain and sewer system is absolutely tight. As one of the few certified sealing testing companies in Austria, we carry out this test for canals, shafts and separator through. Such proof is often required for official approvals or after restructuring.
Overview of features:
- Range of use: Official proof of the tightness of canals, shafts, separators and complete systems.
- main advantage: You will receive a recognized and complete test report as legally secure documentation for authorities or insurance companies.
- Technical details: Inspection by a certified Sealing testing companies according to the strict requirements of ÖNORM B2503.
Channel location with tracking device
Channel location using a tracking device is used to determine the exact course and depth of existing channel systems. This location is important in order to avoid expensive damage to the pipes during planned earthwork and drilling work. It is the ideal procedure when there are no or only inadequate construction plans and thus ensures maximum planning security.
Overview of features:
- Range of use: Exact location of pipes before construction, earthwork or drilling work as well as the Localizing collapses.
- main advantage: Maximum planning security and prevention of expensive damage to existing sewer systems.
- Technical details: Precise determination of the course and depth of the lines using modern tracking technology.
