Resumen
Prefabricated slab, composed of alignments of ceramic pieces (1) that make up a central longitudinal channel (2), an upper step (6) along one of the sides, and a lower step (7) along the opposite side. The longitudinal channel (2) accommodates a reinforcement and is filled with concrete 5 until it fills with the upper surface of the vaults, defining a continuous surface on which a non-cross-linked expanded polyethylene layer and closed cells is disposed.
