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.
