An improvement in the bearing capacity and reduction in settlement of soft deposits can be effected by the installation of stone column. The cost consideration for utilizing the poor and marginal sites efficiently have therefore becomes a subject of profound interest for the employment of stone column. The stone columns provide strength reinforcement to the soil and due to their relatively high modulus, a large portion of the load applied to the ground surface is transferred to them. The stone columns act as vertical drains and accelerate consolidation. From the economic point of view Composite Stone Column and Floating Stone Column gives saving of about 30 % in stone aggregate, besides marginal reduction in ultimate load capacity. i.e. 0.56 % and 1.13 %, respectively.
