An apparatus and method for ground improvement includes 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. The device is retracted and driven repeatedly to achieve densification. Optionally, voids made by the device can be filled with a flowable media.
