Summary:Abstract Biocementation is a technique in which calcium carbonate (CaCO 3 ) gets deposited with the help of ureolytic bacteria. In this study, an attempt has been made to augment the properties of mortar utilizing bacterial solution made with soil bacteria and other nutrients. The consequence of bacterial solution was noticed in two methods. In the first method the bacterial solution is used in preparing the bacterial mortar specimens and in the second method the bacterial solution is used in surface treatment of mortar. Considerable enhancement of 20.08% in compressive strength and 10.52% decrement in water absorption of bacterial mortar over conventional mortar was observed at the end of 56 days of curing period.
