Study of degradation processes of geomaterials, geostructures, and civil engineering structures

The Thematic Research Unit on Environmental Geomechanics (TRU GEOMEC) aims to gain new knowledge on the effects of microstructure evolution on the behavior of geomaterials under complex stresses and to propose technical solutions for managing the interactions between structures and the environment.
