The cementing properties of materials are responsible for the sustainability of any structure. In the present study gives a layout of the improvement of durability of a structure by introducing an ureolytic bacteria. The bacteria which are capable of CaCO3 production in a common metabolic process are called as Ureolytic bacteria. The Ureolytic bacteria having a special quality for healing the crack and can strengthen the structure to make it more durable. Different tests have conducted like consistency and initial setting time are done to discover the impact of bacterial arrangement on cement. Tests such as compressive strength and sorptivity test are utilized as a part of the present examination to recognize the variety in the mechanical properties of cement mortar. The UV- spectrophotometer is use to know the wave-length of the absorbance from that the beer Lamber's law can be verified i.e. concentration is directly proportional to wave length. The bacteria which are introduced in the mortar by replacing the water with the bacterial solution can gives low sorptivity and high compressive strength at a particular range which has been founded during the investigation.
