Solexperts France

Solexperts France was founded in 2002 in view of the research programmes at ANDRA's rock laboratory CMHM (Centre de Meuse/Haute-Marne). Today, the engineers and geologists of Solexperts France are an integral part of the research community at the laboratory. They install geotechnical sensors, instrument boreholes with packer systems, carry out hydraulic, pneumatic and rock mechanics tests or supervise geochemical experiments. Solexperts France has diversified considerably in recent years and is now active throughout France with all the services of the Solexperts Group. 

Strong innovation thanks to research collaboration with GeoRessources

A very successful collaboration has established between Solexperts France and the Institut GeoRessources of the University of Lorraine on many research programmes.

OUROBOROS, Deep Surf, Rostock-H, Regalor, CO2 Dissolved are all research projects related to the energy transition. GeoRessources and Solexperts France have therefore developed new, innovative measurement and evaluation methods. Current reference: Fonts Bouillants

Gas measurements

The SysMoG® gas measurement system is a product of the collaboration between Solexperts France and GeoRessources. SysMoG® is a probe for the automatic and continuous measurement of gas concentrations in the subsurface.

Fibre Optic Sensor Technology

Solexperts France has developed a high level of expertise in high-precision, temperature-corrected strain measurements over the last few years. We offer a comprehensive service including preparation, installation as well as data acquisition and processing.
