Head of R&D

We conduct geophysical surveys to investigate the subsurface and detect structural anomalies. We utilize both established engineering geophysical methods and advanced measurement systems.

Our work focuses on cavity exploration, the detection of underground structures, and the characterization of the subsurface’s physical properties. Typical applications include the exploration of historical mines and investigations at depths of up to approximately 50 meters. We also have experience in exploration projects throughout Europe.

Depending on the specific requirements, the measurement systems we employ are either ground-based or drone-based. The combination of diverse geophysical methods and modern platforms allows for efficient measurement and comparative analysis of the results.
