It discusses the archaeological study of architectural monuments over the period of the operation of the Ukrrestavratsiia Corporation and presents the observation that most known varieties of masonry systems, featuring different combinations of materials and mortars, were observed in findings dated to the period of the Kyivan Rus, and that the list of foundation schemes present was limited to a few types. It was also found that of the schemes observed, the Old Russian scheme displayed an evolution. The study also highlights the significance of the role of foundation musealisation in the restoration and reconstruction of damaged architectural monuments.
