Detecting hidden leaks and underground services without demolition

Yes, the FLIR thermal camera is designed for exactly this. It does not physically “see” through the materials themselves; it captures the infrared radiation and the temperature differences at their surface. Because damp zones behind walls, screed or tiles change the temperature of the material, the camera renders them instantly as clear temperature anomalies.

Condensation is surface moisture caused by warm, humid air meeting a cold surface (a cold bridge, for instance). An active leak is water entering from inside the wall or the floor because of a plumbing fault or compromised waterproofing. By combining a FLIR thermal camera and a moisture meter, we can determine with 100% accuracy whether the damp is at the surface (condensation) or coming from depth (a leak).

An ordinary geophone requires the operator to walk step by step along the entire route of the pipe, which is difficult over long distances or with deeply buried networks. The SebaKMT correlator calculates the position automatically through a mathematical comparison of the noise from two points. This is the most reliable way to diagnose trunk water mains and long supply lines between buildings.

In the case of a complete blockage and standing dirty water, the camera has no way of seeing through the murky liquid, particularly in large pipes above Ø300. In such situations we first carry out cleaning or high-pressure (hydrodynamic) clearing with our combination machines, then introduce the camera for inspection.

Depending on the material and type of pipe, electromagnetic locators, signal transmitters, sondes or other survey methods can be used. Where conditions allow, the route can be followed from the surface and marked out without digging along its whole length first.

The charge for fitting the seal itself is set by the utility and is paid by the customer – in Sofia that is a few euros per meter. The work on the assembly is priced separately: replacing the meter, changing a stopcock, or building a new assembly. That is why we inspect first and tell you what your case actually requires before you commit to any spend.

The DRYMAT® system works with regulated direct voltage in the low-voltage range. Installed professionally and operated as intended, it is designed for permanent use in buildings.

What governs it are the applicable requirements for electrical safety and electromagnetic compatibility (EMC), along with the documentation of the manufacturer.

Depending on the complexity of the car and its construction (a panoramic roof, numerous modules), diagnosis with ultrasound and smoke usually takes between 1 and 3 hours.

Yes. After every thermographic and moisture-metering diagnosis an official technical report is produced. This document contains thermograms (heat images), real-time photographs, a professional conclusion on the source of the fault and recommendations for putting it right.

For maximum accuracy, the surfaces in the inspection zones must be dry (not wetted with water immediately before the inspection). If you suspect damp around central or underfloor heating pipes, it is advisable to switch the system on 2–3 hours before our team arrives, so that the temperature difference needed for the thermal camera is established.

Yes, this is one of the greatest advantages of Echologics systems. Because plastic pipes muffle sound very quickly and standard instruments struggle, Echologics uses specific sensors and software optimised to capture the low-frequency sounds typical of polyethylene pipelines.

When surveying large collectors (from Ø300 to Ø1500) it is desirable for the water flow to be reduced or diverted if possible. Our robots are heavy and stable, however, which allows them to move and record successfully with a moderate level of water at the bottom of the pipe.
