Summary:FIELD: building industry, particularly underground building structure construction and maintenance, namely by filling joints, cracks and cavities of underground building structures. ^ SUBSTANCE: method involves filling cavities with hardening mortar, namely aqueous solution of anionic polymer through orifices preliminarily formed in building structure. Anionic polymer has concentration of 0.1 - 5 % by weight in aqueous solution and viscosity of aqueous solution is 1000 - 10000 MPa.sec. Aqueous solution may be mixed with asbestos fiber and/or cement. Hardening agent may be optionally added to aqueous solution. ^ EFFECT: increased repair intensity, reduced cost. ^ 5 cl
