The slab is then laid. Only at this point the completion casting is carried out, according to the instructions and prescriptions of the manufacturer and/or supplier of the floor.
If prestressed panel slabs are used for hollow-core or similar type floors, the anti-tipping systems installed on the primary beams must be used before the element is released.
The completion of NPS® beams is usually done with standard (non-self-compacting) concrete and is done without the risk of air bubbles. Vibration is also simple, thanks to the lattice structure of the beam itself.
