A precast floor slab is an element produced at the plant and pulled together with the assembled elements in order to create a continuous surface. Modern precast technologies have produced several structural systems using different types of precast floor slabs. Thanks to the prestressing technique, it is now possible to improve the strength properties enabling high loads on large spans, limiting the element weight and increasing its fire resistance. The latest products in the art have a flat intrados and high static performance thus offering a sound alternative to honeycomb floor stab without being obliged to forego the possibility of using large structural frameworks.
