The paper discusses specific reasons for strengthening footings and reinforcing foundations and explores the principal technologies for installing auger cast piles used for reconstruction of building systems. In order to identify the key benefits of using auger cast piles, the existing technologies are analyzed based on the study of domestic and foreign patents. The main principles are set out underlying an economically sound, technically and technologically justified choice of foundation reinforcement technology.
