International expertise in geotechnics and hydrogeology

The Solexperts Group is involved in renowned projects worldwide with geotechnical and hydrogeological instrumentation and field tests. The projects include tunnelling, hydraulic engineering, special civil engineering, wind energy plants and research projects for nuclear waste disposal as well as for geothermal energy and the sequestration of CO2.


Geotechnical instrumentation, measurements and field tests provide reliable information on the in-situ behaviour of structures located in difficult ground. They also form the basis for safe, cost-optimised and time-optimised construction.


Groundwater is an important ressource that has to be protected. At the same time, groundwater is also a risk factor – for example in civil engineering – and, in addition, is a transport medium for pollutants.


The development and use of automatic data acquisition systems (DAS) has been a major activity within Solexperts for more than 20 years.
