Degradation and instability afflict existing buildings and structures and may represent a problem in terms of safety, comfort and low maintenance and/or repair costs.


The thermographic analysis allows to evaluate important information on the whole “building” both for the purposes of static analyzes and for the preparatory checks for the Energy Certification.

APPLICATIONS: research for thermal bridges, analysis of transmittance characteristics, search for heterogeneity in the wall texture, identification of structural elements

EQUIPMENT: thermal imaging camera, surface temperature and humidity detectors

Rebars detector

The pulse-induction method is based on electromagnetic pulse induction technology to detect rebars. Coils in the probe are periodically charged by current pulses and thus generate a magnetic field. On the surface of any electrically conductive material which is in the magnetic field eddy currents are produced. They induce a magnetic field in opposite directions. The resulting change in voltage can be utilized for the measurement. Rebars that are closer to the probe or of larger size produce a stronger magnetic field.

APPLICATIONS: search for reinforcing bars, localization of curbs, identification of floor ribs

EQUIPMENT rebars detector
