Some applications are: soil stabilization prior to tunnelling and prevention of liquefaction of the subsoil resulting from earthquakes. Biogrout is based on microbial induced carbonate precipitation. Bacteria and reactants are flushed through the soil, resulting in calcium carbonate precipitation and consequent soil reinforcement. The carbonate precipitation causes a decrease in porosity. Hence, also the permeability decreases, which influences the flow. The changing composition of the fluid results in a changing density, which also influences the flow. A mathematical model was created to describe the process and some results are shown.
