Solexperts AG (soil experts) was founded in 1947 by Giovanni Rodio. Until 1973 Solexperts was an engineering office and soil mechanics laboratory for the Rodio Solétanche Group.Since 1990 Solexperts AG is an independent company with today about 80 employees in Switzerland, France (Solexperts France SARL) and Germany (Solexperts GmbH, MeSy in Bochum, GTC Kappelmeyer in Karlsruhe). We developed measurement methods and instruments for numerous projects with our electronic and mechanical workshops and built up an excellent reputation worldwide with our instruments and in-situ testing. The orientation of Solexperts is consistently aligned with the new needs of the energy transition in terms of characterization and monitoring of the geosphere. In recent years, an ambitious R&D strategy was pursued to develop new measurement systems and procedures using the latest technologies. Clients are mainly leading scientific institutions, but also construction/engineering companies, government agencies and local authorities.

Solexperts manufactures monitoring systems for soil gas and dissolved gases as well as in-situ gas sampling systems for boreholes up to 1500 metres deep. The product family sets new standards in terms of detectability and allocation of dissolved gases to the source formation and thus opens up new possibilities in the prospection of hydrogen, helium and natural gas as well as the monitoring of geological CO₂ deposits or underground hydrogen storage facilities.The diagram opposite shows possible applications of the various systems for measuring dissolved gases in groundwater down to a depth of 1500 metres. The probes are the result of many years of very successful collaboration with the GeoRessources laboratory at the University of Lorraine and the CNRS.
