Summary:PROBLEM TO BE SOLVED: To provide a repair method which can easily stop water leakage for a long period of time with respect to a crack accompanied by the water leakage which occurs at a skeleton, and a repair body of the skeleton which can stop the water leakage for a long period of time.SOLUTION: This repair method of a crack of a skeleton accompanied by water leakage includes (i) a first adhesion process, and (ii) a second adhesion process. (i): In the first adhesion process, quick-setting cement is made to adhere to the skeleton while covering the crack of the skeleton accompanied by the water leakage. (ii): The second adhesion process is performed after the first adhesion process, and a one-pack moisture-curing type resin composition is made to adhere to the skeleton while covering the quick-setting cement after the first adhesion process. A repair body 100 of the skeleton includes the skeleton having the crack 910, the quick-setting cement 210 which adheres to the skeleton 900 while covering the crack 910, and a one-pack moisture-curing type cured resin 220 which adheres to the skeleton 900 while covering the quick-setting cement 210.SELECTED DRAWING: Figure 1 【課題】躯体に発生した漏水を伴うひび割れに対して、容易に、かつ長期に亘って漏水を止めることができる補修工法、および、長期に亘って漏水を止めることができる躯体の補修体を提供する。【解決手段】本発明の漏水を伴う躯体のひび割れの補修方法は、（i）第１接着工程と（ii）第２接着工程とを含む。（i）第１接着工程では、急結セメントを、漏水を伴う躯体のひび割れを被覆しつつ躯体に接着させる。（ii）第２接着工程は第１接着工程の後に行われ、第１接着工程の後に、一液湿気硬化型樹脂組成物を、急結セメントを被覆しつつ躯体に接着させる。本発明の躯体の補修体100は、ひび割れ910を有する躯体と、ひび割れ910を被覆しつつ躯体900に接着している急結セメント210と、急結セメント210を被覆しつつ躯体900に接着している一液湿気硬化型樹脂硬化物220と、を含む。【選択図】図１
