Scientific work
The IfG Leipzig - Institut for Geomechanics GmbH - performs research on behalf of its own, of a client or of a third-party. Motivation and aims therefore are:
- Development of innovative tools and approaches for existing or new problems, e.g. improvement of constitutive equations or development of new measurement and testing approaches
- Project execution with respect to specific questions, e.g. barrier integrity of evaporites or clay
- Cooperation in national and international research projects – mutual transfer of knowledge
Since 1990 more than 30 research projects are finished. The work priorities have moved from the underground disposal of toxic chemical wastes towards disposal of radioactive waste in different host rocks (salt / clay) and specific problems (e.g. site selection or assessment of impacts of gas generation in salt repositories):
