In construction sites presence of soft soils especially clays, loose and unstable soils causes a major problem because these soils poses a serious threat to the buildings in the form of collapse or distress. There are lot of methods to improve such soils among which stone column technique is adopted here. They are straight shafted columns that are filled with crushed stones and gravels. The load carrying capacity is affected by lateral bulging of stone columns which disperse the stones in soft clay. Model studies were conducted in the laboratory on stone columns of diameter 2.5cm, length ratio 8 and area ratio 22.67% and to evaluate the effectiveness of cemented stone columns over conventional stone columns.
