A bio-grouting method is utilising the interdisciplinary knowledge to alter sand engineering properties in the subsurface by turning it from the soil like into sandstone like. Bio-grouting utilises soil microbial processes to precipitate calcium carbonate into the soil matrix, which binds soil particles together to increase strength and stiffness of soil. Bio-grouting involves numerous biogeochemical effects, making the process as a completely complex to understand. In this thesis, optimising of the bio-grouting process treated coarser materials, microstructure tracing and a sand column application have been conducted. The outcomes of this thesis establish bases to scale up bio-grouting process from bench scale to field scale.
