A permanent form (13) serving to form concrete structures and comprising sidewalls (11) comprises: an interior form (14) that forms the inner face of a side wall; an exterior form (16) that forms the outer face of the sidewall; and a plurality of vertical reinforcements (17) that are disposed between the interior form and the exterior form and that hold the exterior form alone or together with the interior form. The exterior form and the interior form have: a plurality of base plates (18) that are formed from plastic into square plates and that are aligned so as to be in firm contact with each other in the vertical and horizontal directions; a plurality of central reinforcement plates (19) that are formed from plastic into square plates substantially equal in size to the base plates, that join four adjacent base plates, and that are aligned so as to be in firm contact with each other in the vertical and horizontal directions; and a plurality of end reinforcement plates (21) that are formed from plastic into rectangular plates are arranged into a quadrangular frame so as to join adjacent base plates while being located on the outer edges of the plurality of central reinforcement plates aligned so as to be in firm contact with each other in the vertical and horizontal directions.

A cement form assembly includes cement and a cement form. The cement form can include a ground facing surface extending horizontally on a ground support surface and a cement facing surface extending vertically and contacting the cement. An extension member extends outward from the cement form and includes a surface that extends the ground facing surface or the cement facing surface. The cement form and the extension member are each made, at least partially, of a foam material.

A modular slab, slab system, piles and methods of use thereof are described along with specific applications and methods of manufacture. The slab or slab system may be pre-insulated and pre-finished before being assembled on site. The slab system may be advantageous to use as a replacement for traditional in-situ poured building foundations. The slab system may also have uses in other fields such as for floors, roads, bridges, pavements/side walks and other civil and structural applications.

A multi-piece pre-assembled raft foundation is provided and includes pre-assemble bottom layer rebars of foundation slab, foundation steel columns, upper layer rebars of the foundation slab, and foundation rebars. The pre-assembled raft foundation is transported to a construction site for final assembly. A construction method of the multi-piece pre-assembled raft foundation is also provided.

A foundation for a wind power plant includes a circular or polygonal pedestal divided into several ring sections for carrying a tower and support elements extending radially outward from the pedestal, wherein the ring sections and the support elements are designed as prefabricated concrete elements or are assembled from prefabricated concrete elements, and wherein adjacent support elements are spaced from one another in the circumferential direction, adjacent support elements are each connected with one another by a tangentially extending beam designed as a prefabricated concrete element.

A flat-based foundation for a structural component includes a foundation plate having an underside, an upperside, and a center. At least one first soft layer insert is located on or underneath the underside of the foundation plate. The at least one first soft layer insert is a non-load-transferring layer and is arranged at a distance from the center so that the foundation plate is split into at least one inner load-transferring area and at least one outer load-transferring area.
