Maximum lightening of slabs without reduction of rigidity…
Contruss voided slab system weighs less than do flat slabs of equal thickness. This weight reduction reaches up to 50 percent in some cases; however, the rigidity of the slab will stay constant, leading to the enhancement of floor rigidity without a considerable increase in the loads. The low weight, high rigidity, and the two-way nature of voided slabs enable us to construct long spans with a low ceiling thickness value.
