To provide a construction method that can be expected to provide a long-term water cut-off effect with a simple process, low cost, water cut-off strength, and no risk of material dropping due to vibration or gravity.SOLUTION: A water cut-off construction method for cutting-off leakage water from the joint part 2 of the concrete structure 1 includes a filling step A in which the joint part 2 is filled with the wool 4, a curing step B in which the water cut-off agent 5 is injected into the filled wool 4 and cured, and a sealing step C in which the wool 4 and the joint part 2 hardened by the injection are sealed with the quick setting cement 6.SELECTED DRAWING: Figure 2 【課題】簡単な工程で低コストであり、しかも止水強度を有し、振動や重力による材料の落下の恐れもなく、長期止水効果が期待できる工法を提供する。【解決手段】コンクリート構造物１の目地部２からの漏水を止める止水工法であって、目地部２にウール４を充填する充填工程Ａと、充填されたウール４に止水剤５を注入して硬化させる硬化工程Ｂと、注入により硬化したウール４と目地部２を急結セメント６で封鎖する封鎖工程Ｃと、を含む。【選択図】図２
