    • PROBLEM TO BE SOLVED: To realize a floating countermeasure at a low cost by providing an overhanging slab for preventing the flotation of a foundation around an underground outer wall, setting its thickness between the design ground level and design water level, and sealing generated wastes in the hanging slab. SOLUTION: An overhanging slab 3 for preventing the flotation of a foundation is provided around an underground outer wall 2. An excavation is made down to the design water level, and the portion of the overhanging slab 3 is executed in advance. Industrial wastes 6 generated at the time of construction are sealed in a sandwich shape between a lower layer concrete board 4 and an upper layer concrete board 5. The underground outer wall 2 and the slab 3 are connected together when the underground portion 1a of a building 1 is constructed. The wastes 6 can be utilized for preventing the turnover of the foundation as counterweights, and the wastes 6 can be processed for a floating countermeasure at a low cost without increasing the thickness of the foundation board and the underground outer wall.
