Abstract: A building foundation structure includes a ground improved body obtained by improving a surface layer ground, and foundation concrete placed on the ground improved body. A bottom surface of a foundation concrete located below a building pillar has a four-or-more-sided polygonal shape smaller than the plan shape of the foundation concrete, and a part of the lower surface of the foundation concrete other than the bottom surface is a slope surface connecting the bottom surface and the plan shape. Since the stress from the foundation is transferred to the lower ground in its broader range, the stress transferred to the lower ground can be reduced. In addition, since the placing amount of the foundation concrete is reduced, the construction cost can be reduced.

Abstract: A method for sealing piles in foundations in the construction field, wherein a hollow-body formwork element is used. The method includes: 1) applying a barrier layer to the foundation; 2) introducing a pile into the foundation, the pile being arranged so as to penetrate the barrier layer; 3) applying a hollow-body formwork element along the central longitudinal axis of the pile, the hollow-body formwork element surrounding the pile; 4) introducing mineral binding agents into the intermediate space between the pile and the hollow-body formwork element; 5) connecting the barrier layer and the hollow-body formwork element. The hollow-body formwork element has on the side facing the pile a contact layer, which includes a composite layer of a porous material and/or a sealant. The hollow-body formwork element can remain as a part of the structure and thus can perform a sealing function.
