As more and more land becomes subject to urban and industrial development so good construction sites are difficult to find. In situ ground characteristics of construction site are different from those desired and, almost always, form ideal for a designated need. In many a situations in order to satisfy client’s desire the engineer may be compelled to construct structures at location selected for reasons other than ground support conditions. Thus it has become increasingly important for the engineer to know the extent to which alterations have to make for the construction of an intended structure at a stipulated site. Ground improvement in this broadest sense is the alteration of any property of a soil or rock to improve its engineering performance. This may be a permanent measure to improve the complete facility or a temporary process to allow the construction of a facility. This paper review a widely used ground improvement technique stone columns also known as granular column or granular pile. Numerous instances arise where the soils at shallow depths are inadequate for support of proposed structure in response to such needs special technique for the in-place treatment of ground has been developed called stone columns. This technique is used for silty and clayey soils who have very low bearing capacity. This report covers the study of designing of stone columns, failure mechanisms and installation techniques. A case study has been carried out where stone columns are designed according to given bore log data.
