4. Discussion The experimental data obtained made it possible to analyze the moisture behavior of the concrete specimens and to determine the nature of changes in water content under long-term contact with a NaCl solution. Е valuation of different zones in the samples showed that even after fourteen years of operation, the moisture drops above the level of horizontal injection waterproofing. This is proof that the functional properties of the injection waterproofing have been preserved and it continues to effectively comply with its role. The established distinctions in water content between dry and previously wetted areas verify the predicted dependence of moisture on the environment. However, the most important finding is the stability of the moisture indicators in the upper part of
