The polyurethane and urethane foam injectable materials that are highly competitive with foreign analogues have been designed. A technique for repair and consolidation of cracked concrete and reinforced concrete structures and buildings has been developed. Standard technical documents for the injectable materials and technological processes have been elaborated. A trouble-shooting and repairing complex for implementing the above technique has been designed, installed, and implemented on construction sites. The equipment has been designed and manufactured; a technique for serial production of «A» and «B» components of injectable polyurethane materials has been developed. The pilot batch has been manufactured. Technological processes for preparation and application of the «A» and «B» components of injecting materials in industrial conditions have been elaborated and implemented.
