On 10 September 2026, the workshop “MICP for Sustainable Ground Improvement: From Treatment to Modelling” took place at Ruhr University Bochum within the framework of CRC 1683.

The workshop focused on recent experimental and numerical developments in microbially induced calcite precipitation (MICP) and its potential for sustainable ground improvement.
The programme opened with a presentation by Prof. Alexandra Clarà Saracho (University of Texas at Austin) on the design and evaluation of free-draining MICP treatment of shallow sand layers. This was followed by contributions from Hanieh Babaeizad, Juan Pablo Silva Zambrano and Hossam Abdellatif (RUB, Chair of Soil Mechanics, Foundation Engineering and Environmental Geotechnics) addressing the influence of soil characteristics on treatment efficiency and the mechanical behaviour of biocemented sands, sustainable MICP strategies for foundation reuse, and constitutive and numerical modelling of biocemented soils.
The workshop brought together different perspectives ranging from soil treatment to mechanical characterisation and numerical modelling, providing a stimulating platform for scientific exchange on future applications of MICP in sustainable geotechnical engineering.
