The application of jet grouting has been becoming more widespread in the reinforcement of building foundations. This technique depends on the characteristic features of the foundation soil, relevant type of foundation and surrounding conditions. The numerical analysis was carried out with three typical load intensities, proving that the intensity of the foundation settlement being influenced by the growth of soil stiffness and strength. The calculation of vertical soil displacements is 7.9 mm before underpinning, while it is 6.5 mm after underpinning. It is defined that the use of jet structures to strengthen the ground base allows to increase the rigidity of the base and to reduce its vertical movement by 20%. The hypothetical displacements were identified of the base by varying of its mechanical properties to the optimal values.
