The most important aspect in any project is its durability and economic criteria. Recently many bio-enzymes have come into existence and these were used in many constructions works. The areas of Bagalkot are covered with Black cotton soil and few areas with Red soil which have less bearing capacity. The present paper describes a study carried out for improving of geotechnical properties of soils. The collected soil samples were treated with the commercially available Enzyme and were cured for

The results of Consistency limits, Compaction test, Free swell index (FSI), Unconfined Compressive Strength (UCS and California Bearing Ratio (CBR) of untreated soils are presented in this paper. The engineering properties obtained for different mix proportions of soil and curing period were studied. The Free swell index (FSI) and the soaked CBR tests were conducted for the stabilized soil at different curing period.
