Russian method for soil compaction with the help of the vibrating driver of longitudinal vibration with a spatial compactor is used throughout the world for vibratory compaction of sandy foundation soils which can be water-saturated or slightly damp or combined together. The paper provides the results of the theoretical justification on the basis of a design model and field tests of this method for deep vibratory compaction of foundations, which show its disadvantages. These disadvantages manifest themselves the most clearly during the compaction of especially thick sandy foundations (9 m and more). This paper shows that the disadvantages of the well-known vibrating driver can be eliminated or reduced dramatically when using a vibratory compactor with radial elements placed at a certain height at the lower part of its rod. This helps to improve the performance of the vibrating driver when it is used together with a reliable and economical vibratory device.
