Chair of Subsurface Engineering

Innovation Center for Geo-Materials

The facilities of the chair has its own material testing ( Innovation Center for Geo-Materials) .
It includes instruments and systems for determining soil physical and mechanical soil parameters for subsequent lines corresponding to the cutting edge of technology.
