The study is aimed at studying the corrosion processes of a metal waterstop inside technological seams in order to ensure its tightness and maintain performance qualities, since if corrosion occurs, the waterstop may lose its functional properties, which can lead to groundwater leaks. At the moment, there is no single source containing a complete set of information on corrosion processes in relation to metal waterstops, which leads to design errors, since it is extremely difficult to make the correct choice of metal waterstops, because it is impossible to analyze data and determine the parameters that determine the corrosion rate of metal waterstops in the technological concreting seam, it is necessary to take into account a large number of parameters related to the study of groundwater.
