Weak soil, which has very low shear strength and high

compressibility to support structures require strength

to be capable of carrying loads from structures. Stone

columns are ideally suited for structures.

Economical (alternative than others)

Quicker alternative. (no waiting period after the installation)

Stone columns improves the strength of parameters of soil like bearing

capacity and reducing consolidation settlement.

Reduce the risk of liquefaction.

Homogenized the variable of soil property.

To enhance drainage conditions and sustainability of the natural
