This open access book summarizes the results of the collaborative project ¿GeomInt:
Geomechanical integrity of host and barrier rocks - experiment modeling and analysis of
discontinuities¿ within the Program: Geo Research for Sustainability (GEO: N) of the Federal
Ministry of Education and Research (BMBF). The use of geosystems as a source of resources a
storage space for installing underground municipal or traffic infrastructure has become much
more intensive and diverse in recent years. Increasing utilization of the geological
environment requires careful analyses of the rock¿fluid systems as well as assessments of the
feasibility efficiency and environmental impacts of the technologies under consideration. The
establishment of safe economic and ecological operation of underground geosystems requires a
comprehensive understanding of the physical (geo)chemical and microbiological processes on all
relevant time and length scales. This understanding can only be deepened on the basis of
intensive laboratory and in-situ experiments in conjunction with reliable studies on the
modeling and simulation (numerical experiments) of the corresponding multi-physical chemical
processes. The present work provides a unique handbook for experimentalists modelers analysts
and even decision makers concerning the characterization of various types of host rocks (salt
clay crystalline formations) for various geotechnical applications.
