INTRODUCTION
Ground improvement technique is the process of improving the geo-technical characteristics of soil used in construction.
The soil at a construction site is not always totally suitable for supporting structures such as buildings, bridges, highways and dams. For example, In granular soils, in-situ soil may be very loose and indicate large elastic settlement. Under these conditions, soil needs to be densified to increase its unit weight and shear strength.

Objectives of ground improvement is to:
1.Reduce settlement of structures.
2.Improve shear strength and bearing capacity of shallow foundations.
3.Increase factor of safety against possible slope failure of embankments and dams.
4.Reduce shrinkage and swelling of soils
