Objectives: To explore bio-mediated method to strengthening soil engineering parameters. Methods: Besides, issues such as environmental pollutions engineers invent new methods for improving mechanical soil properties. During the last decade bacteria cultivation technique has become one of the innovative methods which are more capable compared with other methods. Results: The new method named Microbial Induced Calcite Precipitation (MICP) provides a suitable condition in order to derive calcite between sand particles by adding cultivated bacteria and cementation solution to it. In fact, reaction between these solutions creates strong bonds which lead to strengthening physical properties of sand. Conclusion: The direct shear test and unconfined compression test results demonstrate non-homogeneity distribution of solutions in the sand samples.
