PROBLEM TO BE SOLVED: To provide a repair method for concrete capable of safely and securely filling a repair agent into fine crazing occurring in the concrete by applying a pressure thereto. SOLUTION: A filling hole 12 is drilled in the surface of the concrete 10 in which crazing occurs. An anchor 31 is fixed to the inside of the filling hole 12, and a bar-like member 30 is fixed to the fixed anchor 31. An alkali metal silica salt water solution pressurized by a pump is pressingly filled by using a filling plug 20 fitted to the opening part of the filling hole 12 by fixing to the bar-like member 30.
