The review of soil types prevailing in Western Siberia of the Russian Federation is presented. The compositions and physical and mechanical properties of soils are analyzed. Special attention is paid to loess subsidence soils. The problem of obtaining a homogeneous cement-ground mixture is formulated and set. The technological scheme of production of cement-ground piles of foundations of buildings and structures by drilling-mixing method with mechanical activation is considered. Considers methods of strengthening the loess subsidence of soils. Methods for studying the properties of cement-based piles of foundations of buildings and structures are formulated. A multi-factor experiment was conducted to evaluate the parameters that affect the properties of cement-based piles. Based on the research results, conclusions and recommendations are formulated.
