ISO
Certification
Our processes are certified according to DIN EN ISO 9001:2015
We detect the leaks fast and accurately, determine the cause, and visualize groundwater flows.
Our customers stay on schedule for completion during construction works and save significant costs through targeted remediation according to our precise measurement results.
WE ARE SPECIALISTS IN DETECTING LEAKS
YOU BENEFIT FROM OUR SERVICE AND KNOW-HOW
One of the major advantages of the measurement with our patented leaking detection technologies is that the sealing constructions do not have to be emptied or cleaned and can be carried out regardless of the construction material.
Natural and artificial groundwater flows of unknown origin and depth through concrete and steel constructions will be accurately located independently of their depth.
Our measuring sensors can be placed either directly at ground level or into the water.
We use our technology and knowhow for measuring larger areas under difficult conditions, e.g. in metro stations, railway tunnels or industrial plants.
Our leak detection services do not include repair works.
We can help you
- Define the exact location of the damage
- Avoid high costs for pointless extensive repair works
- Quality control during and after the remediation process

HOW IT WORKS
ACCURATE AND RELIABLE
LEAK DETECTION ON SURFACE OR UNDER WATER
Leakages in horizontal and vertical sealing systems can be detected accurately and reliably with our FGM® leak detection technology.
The measurements are carried out non-destructively on the surface or underwater.
Leakages are localized on the basis of potential differences that are registered in a fixed measuring grid with sensors. The measurement grid can vary from half a meter to about twenty meters, depending on the purpose, accuracy, etc.
The sensors are placed directly on the ground and are connected by a cable to the measuring units.
Prior to an investigation (and for determining the cause of the leak) all available information about the object to be investigated should be made available. This includes drawings of the building/construction, information about the lithology, information about previous (repair) work carried out, photographs and consultations with the client, etc.
The duration of a leak detection depends on the size, surface area and/or length of the investigated area. The client receives a clear overview drawing accompanied by an extensive report. If desired, the results are presented to the client and explained in detail.
STAY ON SCHEDULE
SAVE TIME AND MONEY WITH TARGETED REPAIR WORKS
Quality controls of horizontal and vertical waterproofing systems immediately upon completion of the construction works minimize the risk of high sanitation costs due to re-mobilizing the equipment to the building site. Acceptance and commissioning of the building stay on schedule. Moreover, the success of sanitation works can be controlled continuously.
The sanitation and grouting of the defective areas can be done immediately during the construction phase, thus reducing our customers’ costs considerably.

TECHNOLOGY
QUALITY AND RELIABILITY THROUGH PATENTED TECHNOLOGIES
From the start of our business we have specialized in research and development on inspection technologies for sealing systems in civil and structural engineering.
Most of our technologies are patented and developed in-house. Our methods and processes are certified according to DIN EN ISO 9001:2015 and ISO 45001 (in the Netherlands).
FGM® LEAK DETECTION TECHNOLOGY
The FGM® (Flexible Groundwater Monitoring) is an electrical multi sensor technology to investigate groundwater movement in the sub-surface and detecting leaks in sealing systems.We use this technology for surveying large areas with complex constructions.
It is a perfect method to detect ground water streaming through leaks in vertical and horizontal concrete or steel constructions, specially in very deep buildings for metro and tunnels without depth limit.
GEOPHYSICS
In addition to our self developed FGM® technology, we use traditional geophysical measuring techniques like radar (GPR), electrical resistivity tomography (ERT), and microgravity to investigate subsurface structures and locate anomalies.
