Methods of construction of Granular piles

Granular piles can be installed by various methods depending upon their proven applicability and availability of equipment in the Locality ,

Vibro compaction:

Used to improve the density of cohesion less soil

Vibro float sinks under its own weight and with assistance of water and vibration. After reaching a predetermined depth the vibrofloat is with drawn gradually from the ground with subsequent

addition of granular back fill causing compaction.
