Abstract: 
Optimal polyol components formulas for preparation of liquid injection polyurethane compositions providing strengthening and restoration of serviceability of concrete and iron-concrete structures and constructions damaged by cracks are cited. Standards and norms for equipment and technological processes of pilot-industrial production of polyol components have been developed. Technological processes of preparation and practical use of polyol components for preparation of liquid injection polyurethane compositions in industrial conditions have been worked out and implemented.
Keywords: concrete, crack, injection, iron-concrete, polyol, polyurethane material, restoration, structure
