Abstract
A method for ground improvement with hardened inclusions includes providing a device having a plurality of tines extending downwardly from a top plate in a manner to achieve displacement of ground material downward and radially outward. The device is mechanically driven into the ground to achieve predetermined depths of penetration by the tines and to create cavities at the location the tines are advanced. The device is at least partially retracted and hardening cementitious material backfill is added into the cavities for forming a plurality of hardened inclusions within the cavities.
