Test method for monolithic reinforced concrete foundations is proposed. On its basis, an experimental assessment of the state of monolithic reinforced concrete structures of the foundations of the capital construction object was made: “Platforms of RM, RS in the area of ​​the village of Karamaly Nikolsky district of the Penza region "with the definition of physical and mechanical characteristics of materials. As a result of the tests, the bearing capacity of the foundation blocks throughout the construction site was confirmed. The article material was prepared on the basis of the materials of the research work No. 18-156 of 08.21.2018.
