PROBLEM TO BE SOLVED: To provide a method for mending a core hole in a concrete skeleton, wherein the core hole made for the purpose of taking a core sample is mended with high reliability by means of filler filling, a mending apparatus for the fore hole and also a filler-filling tool used for the mending. SOLUTION: A core hole 1 bored in a concrete skeleton such as a column, beam or the like is mended by filling a filler 2. The apparatus used for mending the core hole is composed of a rod 4 mounted in the core hole 1, a pressure plate 3 placed at an entrance portion of the core hole 1 and pressing the filler 2 filled in the core hole 1, a pressure nut 6 screwed with the rod 4 for pressurizing the pressure plate 3 into the core hole 1. The pressure nut 6 screwed with the rod 4 is clamped down, and thus the filler 2 filled in the core hole 1 is pressed by the pressure plate 3 from the back, so as to improve filling property of the filler 2.
