PROBLEM TO BE SOLVED: To provide a water block method of water block area, and a water block structure.SOLUTION: The water block method of water block area is configured so that a flexible resin sheet 12 covers a water block area (subsurface cavity water tank 100) in which a metal rigid structure 24 is installed. On a surface of the metal rigid structure 24, a coating layer 34 is formed for installing the metal rigid structure 24 in the water block area. The water block area is covered with the resin sheet 12, and the resin sheet 12 and the coating layer 34 are deposited, for water block between the resin sheet 12 and the metal rigid structure 24. 【課題】遮水領域の遮水方法、及び遮水構造を提供する。【解決手段】金属製剛性構造体２４を設置する遮水領域（地下空洞水槽１００）に可撓性の樹脂シート１２を覆う遮水領域の遮水方法において、前記金属製剛性構造体２４の表面にコーティング層３４を形成して前記金属製剛性構造体２４を前記遮水領域に設置し、前記遮水領域に前記樹脂シート１２を覆うととともに前記樹脂シート１２と前記コーティング層３４とを溶着することにより、前記樹脂シート１２と前記金属製剛性構造体２４間の遮水を行うことを特徴とする。【選択図】図２
