METHOD FOR REPAIRING WALL SURFACE

摘要

PROBLEM TO BE SOLVED: To provide a method for repairing a wall surface wherein a driving hole for an anchor pin, with an injection port, bored from the surface of a tile toward a concrete frame can be finely finished. SOLUTION: A repairing material 13 is injected into a repairing hole bored through a tile 3 and a cement mortar 2 as far as a concrete frame 1 to force the repairing material 13 into gaps formed between the concrete frame 1 and the cement mortar 2 and into gaps formed between the mortar 2 and the tile 3. A plug body 15 made of the same kinds of tile as the tile 3 is bonded to an open portion in the surface of the tile for the repairing hole. An anchor pin 10 with an injection port is driven into the repairing hole to fix the tile 3 and cement mortar 2 to the concrete frame 1 by means of the anchor pin 10 with an injection port.
