The ground upon which the foundation was built is unique in that it contains a just below the surface that is approximately in overall depth. Radioactive contamination from the accident created the technogenic layer. It consists of various materials including nuclear material, stone, sand, loamy sands, unreinforced concrete, and construction wastes. It is considered unfeasible to determine the geotechnical characteristics of this soil layer. As a result of this, no assumptions about the load-bearing properties of the technogenic layer were made during the design of the foundation.
