The article is devoted to the possibility of reuse of reinforced concrete structures formed during the demolition of buildings. The analysis of the strength parameters of reinforced concrete elements of the frame in order to reuse them as a construction of foundations and retaining walls in the new construction of low-rise buildings. Solved the problem of disposing construction debris without taking it to the dumps of solid waste. Sharply reduced the cost of foundations.

Keywords: reuse of structures, demolition of buildings, building elements, reinforced concrete foundation structures
