Abstract
Recent years have seen the growing interest in the novel field of biogeotechnologies. Of particular interest to researchers has been the microbially induced calcium carbonate precipitation (MICP) for geotechnical (stabilisation of soils) and geoenvironmental (immobilisation of contaminants) applications. The MICP process results in the formation of a brittle monolith from sand cemented by the microbial calcium carbonate which will, however, be subjected to chemical and physical deterioration over time. This will bring the need for repair of the earth structure which can be highly difficult and costly. This study investigates the possibility of incorporating a se...
