PURPOSE:To ensure a waterproof seal by a method wherein the end parts of the waterproof sheets are joined to each other by face fasteners and layer are waterproofed by a heat-sealing or other method. CONSTITUTION:To the end parts of the sheet 1 to be joined are attached the face fasteners 2 nearly throughout the full length of the sheets with margins, for instance, of 5-20cm being left. Next, the sheets thus prepared beforehand are joined primarily by the face fasteners 2. And, after the application of primer on to the surface to be joined or the like is performed as occasion calls, the heat-sealing 3 is conducted by using a heat sealer. Since the parts to be joined is joined, above all, surely in physical terms, it becomes unnecessary to keep the sheets being pulled and picked up during heat sealing. Moreover, since the surface to be joined can be preprocessed with margins, the heat sealing can surely be performed. |
