Abstract. Domestic and foreign experience in the use of heavy rammers when compacting soil bases of buildings and structures as well as the further development of this method and technologies of soil compaction works is considered. Limits of the applicability of this method depending on the degree of soils dampness are established, possibilities to use the compacted base as an artificial base of industrial, civil, and transport facilities are shown. The essence of this method is the improvement of mechanical properties of soils by transmitting high-energy impact effects on loose soils. When using heavy rammers, an important element is the control of the quality of the compaction. This method, in comparison with the use of pile foundations, makes it possible to arrange soil bases, significantly reducing the time and cost of the work execution under complex engineering-geological conditions.
