Stone Column is a ground improvement technique used to improve the load bearing capacity and reduce the settlement of soil. It is also called granular column, granular piles or vibrio-placement.


it involves construction of sense aggregate column of stones by means of suspended down-whole vibrator.


  • Improves the ground by reducing soil settlement

  • Absorbs more load than soil and reduces overall settlement due to its higher modulation of elasticity than that of soil

  • Useful in waterlogged areas

  • Increases the bearing capacity of a site, thus making it possible to use shallow foundation on the soil; thus saving cost and time.

  • Reduces total and differential settlement.

  • Accelerates the rate of consolidation in cohesive soil by providing drainage to water.
