The paper describes the new method developed for foundation strengthening by a drill and inject pile with controlled widening on its end. The method aims at increasing the useable area of the buildings under refurbishment. This is achieved by developing the underground space and/or adding floors. In-situ tests were carried out on a construction site in the city of Tyumen in order to implement the method on an industrial scale. The in-situ tests resulted in determining the radius of the compacted zone of soil massif, the geometric parameters of controlled widening, the vertical and horizontal deformations of the soil massif in the pile area and the changed physical and mechanical characteristics. The article describes the production of a new method for reinforcing foundations in the form of a drill-injected pile with controlled broadening at the end.
