BioGrout is a new promising material to be used for ground improving purposes based on microbial induced precipitation of carbonate by urea hydrolysis. Previously performed large scale experiments and subsequent tests on compressive strength give promising results, especially with regard to the fact that BioGrout can be created with various strengths. The process of cementation can be controlled in order to yield a strength desired for a specific application. However the long term effects on BioGrout in regard to mechanical requirements imposed by civil engineering applications and exposure to chemical processes in the subsurface are not yet known. In order to determine the behavior of BioGrout once exposed in a specific environment laboratory tests were conducted.
