This study presents the results of research on the influence of a modified additive on the strength characteristics of injection grouts used in the deep cementation method. The primary component of the additive is paraffin, which enhances the plasticity of the mixture and reduces the water-cement ratio, ultimately improving the mechanical properties of the hardened grout. The tests were conducted on beam specimens at different hydration periods to determine the optimal additive concentration that ensures maximum grout strength. The analysis of the results revealed the strength variation dynamics in compression and bending, as well as the most effective additive concentration for further research and practical application. The obtained data may contribute to the improvement of injection-based soil reinforcement technologies and the expansion of deep cementation applications in construction.
