The predalles slabs are prefabricated reinforced concrete products, which are composed of a slab of reinforced concrete in which are embedded pylons placed in the direction of floor warping, spaced with the interposition of lightening elements in expanded polystyrene and additional transversal round elements.

Predalles slabs are used in making floors for the civil and tertiary sector, but can also be used as a cover for basements or garages thanks to the particular soffit finish, which can be left visible without a plaster covering. The floors are designed to measure, as a function of the load requirements requested by the customer.
