The foundation unit has a tubular holder with clamp for a post, and a crumple element encased by a foundation block. The crumple element (2) has a structure, which is open from the interior (4) of the foundation part (1) to the exterior (3), and from the exterior to the interior. The structure is grid-shaped, and is formed by a cylindrical spiral. The viscosity of the medium e.g. soft mortar (5), encasing the crumple element is chosen, so that during filling, it moves by gravity from the exterior into the interior, and vice versa. |
