According to the present disclosure, a concrete casting system including a large number of individual concrete casting boxes is provided. The concrete casting system has a grid-like structure in which the individual concrete casting boxes are arranged at the intersection points of the grid-like structure. Two respectively adjacent concrete casting boxes are connected to one another by means of a spacer. Each concrete casting box has a housing which has at least one opening in a direction perpendicular to the direction of extent of the grid-like structure. The concrete casting system is designed such that it can be rolled up or folded.

A method for manufacturing a prefabricated concrete product is disclosed, in which method, a concrete slab with a recess at its upper surface is cast with slipform casting on a casting bed, and after the slipform casting of the slab the recess of the fresh cast slab is equipped with ducts, piping and/or wiring components, after which the recess is covered with concrete mass, and the concrete product is left to cure. The invention also relates to such a prefabricated concrete product.

Disclosed are embodiments of a method for manufacturing concreate panels for a mechanically stabilized earth (MSE) retaining wall that employ geosynthetic strips that attach to the MSE retaining wall and extend into the backfill soil. One embodiment can be generally summarized as follows: (a) providing a mold for the concrete panel; (b) providing in the mold: (1) a plastic pipe; (2) a metal rod situated in the pipe; (3) a removable block-out insert that creates a geosynthetic strip cavity within the panel body around the pipe for enabling a geosynthetic strip to be looped around the pipe; (c) introducing concrete into the mold; (d) permitting the concrete to substantially solidity within the mold; and (e) after the concrete has substantially solidified, separating the panel from the mold and removing the block-out insert to expose the cavity and the pipe extending through the cavity.

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 method produces a part of a building. The part of a building has at least one first region and one second region, which adjoins the first region. In the first region, an installation structure is concealed by building material. The method includes the following steps: a) dispensing building material to produce the first region and providing the building material with a marking substance before, at the same time as, and/or after the dispensing operation, and b) dispensing building material to produce the second region.
