The article presents an analysis of the requirements for quality control in the current regulatory documentation of the Russian Federation and the experience of developing a scheme of operational quality control (SOQC) for the installation of sheet metal waterstops, obtained on the basis of regulatory and methodological documentation and materials from manufacturers of waterproofing materials: domestic and foreign, and the practice of using polymer and metal waterstops and our own experimental studies. The content of the main information blocks of the SOQC in the practically accepted unification of requirements for quality control in construction is described. Construction defects are indicated when using polymer waterstops for waterproofing technological seams of monolithic structures of civil buildings, which can be avoided if the requirements are met and the work is performed in accordance with the developed SOQC as part of the technological map of the work production project.

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.
