We are incorrectly led to estimate the advantage of a slab lightened with U-Boot Beton limiting it to a mere comparison between savings in concrete and the cost of the formwork on the level of the slabs only. In this way however, as the analysis is immediate and intuitive, it does not account for the various economic, practical and operational advantages provided with U-Boot Beton® for the entire structure: less use of iron in the slabs, pillars and foundation up to a total of 15% (also in the case of variants); less concrete is used not only for the slabs but also for the columns and foundations; there are antiseismic advantages connected to reduced building weight; slimmer pillars and foundations, lower costs related to excavation for foundations; the arrangement, also irregularly if needed, of the pillars to reflect the architectural freedom of the structure. Reduction of work and overhead transfer of the formworks; advantages in on-site logistics.
Possibility to gain floors at the same building height (towers) and building volume.
Larger spaces.
Thinner slabs but with equal loads and clearances, or bigger clearances with an equal thickness.
Flat soffit for greater flexibility when installing systems.
Facilitated use reallocation.
Wider bays.
Less excavation.
Lower costs for foundation excavations.
Less acoustic transmittance
