description: This final qualifying work is dedicated to laboratory studies and numerical modeling of the properties of the fast-reacting two-component polyurethane resin "MC-Montan Injekt LE" of the manufacturer "MC-Bauchemie". The aim of the work is to evaluate the effectiveness of the method of injecting expanding polyurethane resin for the stabilization of the ground base and thermal protection of the foundation. To achieve the goal, the following tasks are completed: 1. A single-axis compression test of the "MC-Montan Injekt LE" material samples was carried out in accordance with DIN EN ISO 844. 2. Long-term load tests (creep tests) of the "MC-Montan Injekt LE" material samples were carried out. 3. Tests were carried out in a high-pressure tank to evaluate the results of the lifting effect when injecting soils with expanding polyurethane resin. 4. Thermal conductivity tests were performed on samples of "MC-Montan Injekt LE" material of different densities. 5. Geometric parameters and forms of spreading of expanding polyurethane resin in the soil mass are determined. 6. The relations between the density and the physical and mechanical properties of the expanding polyurethane resin are revealed. 7. A method has been developed for calculating the load-bearing capacity and evaluating the precipitation of bases reinforced with expanding polyurethane resin. 8. The method of calculation justification of thermal protection of the foundation by injection of expanding polyurethane resin is developed. Based on the conducted laboratory tests and numerical simulations, it is possible to draw a general conclusion about the possibility of successful stabilization of existing ground bases, thermal protection of foundation structures and lifting of structures with the help of the investigated expanding polyurethane resin "MC-Montan Injekt LE" produced by the company "MC-Bauchemie". The results of the research were implemented in LLC "MC-Bauchemie", St. Petersburg, as designing measures for the stabilization of ground bases and thermal protection of foundations by injecting expanding polyurethane resin.
