Bio calcification is a very recent in situ soil consolidation solution. It is obtained by calcite precipitation under controlled biogeochemical conditions. Soletanche Bachy holds several patents for implementing the process by grouting and has developed the Biocalcis process.

It is based on the injection of ureolytic bacteria with a calcifying solution, which leads to the creation of a biological cement that binds the soil grains together without decreasing the initial permeability. The process has been proven by several experiments, initially on laboratory scale then in situ on an industrial scale.

The presentation will summarize the latest developments on the technology and its fields of applications specifically in the fields of liquefaction mitigation, erosion control and soil reinforcement. It will also present some design and modelling aspects together with environmental issues and in-situ controls.

The feasibility of implementation in various soil gradings and configurations, and under several hydraulic conditions will be discussed.

The event is free to attend but advance registration is required; attendees are invited to join the BGA in the ICE Café Bar afterwards for networking drinks sponsored by Bachy Soletanche.
