The invention relates to the technical field of hydraulic concrete repairing, and discloses hydraulic concrete high-performance repairing mortar and a construction technology thereof, and the construction technology comprises the following technological processes: base surface treatment, interface treating agent preparation, interface treating agent brushing, hydraulic concrete high-performance repairing mortar preparation, high-performance mortar repairing and maintenance. In order to increase the freezing resistance of the hydraulic concrete repair mortar, the cement mortar is modified by doping the polymer acrylic emulsion and the instant rubber powder, and a continuous film is formed in the mortar, so that an anti-seepage effect can be achieved, the freezing resistance is further improved, the workability of the mortar is improved, the bonding strength and the abrasion resistance can be improved at the same time, and the service life of the hydraulic concrete repair mortar is prolonged. The shrinkage is r
