摘要： PROBLEM TO BE SOLVED: To provide a water barrier sheet having a multilayered structure, the on-site connection work of which is facilitated. SOLUTION: A first water barrier sheet 11 is composed of a plurality of layers the end faces of which are aligned vertically on the side to be connected to a second water barrier sheet 12. A first protection layer 15a is not stuck to a first water barrier layer 17a by a distance L 1 from the end face. The first water barrier layer 17a is not stuck to a second protection layer 19a by a distance L 2 from the end face. The second protection layer 19a is not stuck to a second water barrier layer 21a by a distance L 3 from the end face. The second water barrier layer 21a is not stuck to a fifth protection layer 23a by a distance L 4 from the end face. These distances are set so that the distance of the upper layer is twice as long as that of the adjacent lower layer. When the first water barrier sheet 11 is connected to the second water barrier sheet 12, the layers of unstuck parts of each of the water barrier sheets 11 and 12 are folded back/fixed one by one successively from the upper layer to the lower layer to expose the lowermost layers, the exposed lowermost layers of the water barrier sheets 11 and 12 are connected to each other and then the corresponding layers of the water barrier sheets 11 and 12 are connected to each other one by one successively from the lower layer to the upper layer.
