In coastal areas most of the land is covered by soft clay. The construction of a structure on the soft clay is quite miserable due to its inadequate engineering properties. The installation of stone column is cost effective method of improving the strength parameters like bearing capacity, reduce settlements and increased rate of consolidation. when stone column loaded in soft clay undergoes excessive bulging due to inadequate lateral support from the surrounding clay soil. To avoid excessive bulging, stone column is encased with geo grids. In present study experiments done on stone column with and without encasement. The stone column is encased with geo-grids of varying encasement depths of 0.25L,0.5L,0.75L, L to improve bearing capacity and lateral bulging.
