In urban areas characterized by complex hydrogeological conditions, the rise in groundwater levels coupled with their aggressive chemical composition exerts a severely adverse impact on the structural strength of multi-family residential building foundations. Chloride ions present in the groundwater initiate reinforcement corrosion within the reinforced concrete structures, inducing internal stresses that lead to structural cracking and macro-fissure propagation. Concurrently, sulfate ions trigger the degradation of the cement stone, significantly accelerating the process of sulfate attack (sulfate corrosion). Consequently, under conditions of dense urban fabric and highly developed infrastructure, identifying ecologically sound and economically viable methods for strengthening the foundations of operational multi-family residential buildings constitutes a critical task in contemporary urban development and engineering.
