A modern and economical solution for measuring the moisture level of a wall. Hybrid tomograph, a professional and technologically advanced tool used to determine the external level of humidity inside the building’s walls.

The system allows for a precise and non-invasive deep structure examination with no need for drilling. An exact image of the tested material is directly displayed on screen using a built-in application integrated with the tomograph system.

How does it work?

The Netrix Hybrid Tomograph precisely analyzes inside of the wall in a non-invasive manner, similar to research equipment used in medicine, e.g. ultrasound devices. The user can quickly take all necessary measurements and obtain their results, without need for costly and invasive drilling or sampling by simply attaching the electrodes to the tested wall and connecting them to the digital module. Measured data is sent to the device which ensures appropriate configuration, and also implementation of the measurement cycle. Then device communicates with visualization system and test results are quickly presented in perspicuous 2D or 3D format.

A tomographic analysis may be applied to historic buildings, several dozen years old (e.g. large slab blocks) and also newly constructed buildings. The device is also useful in analyzing the condition of buildings that were flooded or exposed to other unfavorable external factors. Using the hybrid tomograph in the construction industry and real estate trade saves time and ensures highest precision of tests.

Why a tomograph?

For years experts in the construction and real estate industry have examined the moisture level of the walls of buildings using outdated technologies. To see if there was moisture inside, walls had to be drilled to get the internal material and then tested. It was time and cost consuming, and the measurements did not guarantee a high level of precision.

Therefore, at Netrix, we worked on a new algorithm that would eliminate drilling and provide a deeper level of wall control by analyzing the building’s structure with modern computer technology. This is how the hybrid tomographic system was created, which was an industry-changing replacement of outdated and ineffective methods of testing buildings.

Measurements and interpretation of results

The Netrix hybrid tomograph consists of a measuring device equipped with electrodes and software for the analysis and interpretation of the results. Our system uses impedance and efficiency of tomography, thanks to the use of electrodes fixed on the surface of the tested wall on special rails. The device also allows for examining the condition and quality of reinforcement in concrete walls, which is extremely valuable in determining the condition of objects built of large slabs.

The output data read with the electrode is then sent to the tomograph and displayed on screen. The system uses research methods and algorithms that allow for extremely effective wall moisture examination. The great advantage of the tomograph system is that the measurements can be repeated multiple times without noticing any negative effects on the tested objects. The tomograph is fully usable to perform cyclical tests and analyses, control moisture protection, and can help to develop efficient methods of wall drying.

The hybrid tomograph designed by Netrix S.A. is a modular, compact and configurable device, designed to work in various measurement systems, adapting to the individual user’s needs.

Netrix S.A. is a Poland-based company and an accredited R&D centre. It designs complex solutions including image analysis systems, expert systems and solutions supporting development of companies operating in various industries.
