PURPOSE:To exactly provide a water-proofing work for the connected part between a strip foundation and an underground outer wall by a method in which a formwork of box type is provided in the space adjacent to the outside of the outer wall part including the connected part and a water-proof sheet layer is provided on the inner surface of the formwork crossing the outside of the outer wall. CONSTITUTION:Concrete is placed on the bottom wall of a basement, a formwork 4 for the underground outer wall, a box formwork 5 formed by the space 9 adjacent to the outside of the underground outer wall 1 including a connected part 3 is provided in the connected part between a strip foundation 2 and the underground outer wall 1. Then, a water-proof sheet layer 6 for the underground outer wall 1 is adhered to the inner surface of the formwork 4 for the underground outer wall, a water-proof sheet layer 7 is also adhered to the inner surface of the formwork crossing the outside of the underground outer wall of the box formwork 5, and the end part of the underground wall side is doubled with the water-proof layer 6 for continuation. Furthermore, a strip material of a non- vulcanized butyl rubber-based adhesive composition is provided on the end part of the opposite side of the water-proof layer 7. |
