Different methods are used in the field for foundations remediation and improvement of the soil properties, but every method has its advantages and limitations. Moreover, not all the existing methods are able to stabilize the soil and elevate the foundations effectively, regulating the process depending on the desired results. The settlements of the foundations of the buildings and structures lead to negative consequences and controlling the settlements is complex itself essentially in the type of soils which contains organic materials or acids where the treated materials used might react with the soil components. The soil injection technology using an expandable polyurethane resin is an innovative technique that leads to the stabilization of the soil beside lifting and remediating of the foundations. Therefore, a full-scale experiment has been implemented in-situ to investigate the effect of injecting an expandable polyurethane resin on different soil properties besides lifting a concrete foundation. The paper demonstrates the results of an experiment which has been conducted to improve the soil's modulus of deformation, lifting of a concrete foundation, settlement compensation and increase the bearing capacity of the investigated soil after the injection of an expandable polyurethane resin consists of two components. The deformation modulus (E) of the investigated soil before and after the injection of the resin at different depths are achieved and incorporated. Also, comparisons of the load-settlement graphs at different soil depths before and after the injection of the resin are presented and analyzed. The in-situ injection process and the propagation of the resin in the soil massive are obtained and described in this paper.
