An apparatus for use in compacting or densifying soils includes a tubular casing having a vertical longitudinal axis and an inside surface; a hollow tubular drive shaft aligned with the vertical longitudinal axis of the tubular casing and mounted for rotation therein; a drive motor for rotating the drive shaft; a carrier attached to the drive shaft for rotation therewith; and a cylindrical roller weight in rolling contact with the inside surface of the tubular casing. The carrier engages the roller weight for rotation about the vertical longitudinal axis of the tubular casing. The centrifugal force resulting from rotation of the roller weight is resisted by the tubular casing thereby causing vibration thereof.
