A sustainable and economic method of treating expansive soils could be through Microbial Induced Calcite Precipitation (MICP). Clayey soils are a natural habitat for bacteria and are therefore a promising source for biological calcite precipitation. Evidence of calcite precipitation in natural clays has been seen in laboratory studies. The application of these methods in the field are however yet to be developed. An attempt to implement MICP in the field show promising observations. Further readings are necessary to determine the homogeneity and spatial effects of the treatment in the ground.
