FIELD: building engineering, particularly repairing (recovering) of vertical building surfaces. SUBSTANCE: method involves applying recovering mixture of cement-sand solution and polymeric additive on concrete surface; covering recovering mixture surface with polyurethane composition after recovering mixture hardening. Polymeric additive consists of furyl alcohol and sulphanol in amount of 0.35% and 0.02% of cement mass correspondingly. EFFECT: recovery of bearing strength, increased wear resistance, water-tightness and resistance to corrosive medium. |
