SOUNDPROOF BARRIER

Our Precasting division has designed and industrialized a soundproofing-sound-absorbing barrier system for large road infrastructures, consisting of prefabricated concrete panels, with a sound-absorbing layer of expanded clay concrete. The original production system allows to obtain the surface on the receiving side by casting on a metal formwork base, with low permeability and high durability characteristics and the possibility to customize the design and color of the surface. The horizontal arrangement of the corrugations of the sound-absorbing surface improves the overall sound-absorbing characteristics of the barrier. The specific use of this product for major road infrastructures, especially the new high-speed railway line, has led to the passing of stringent tests and certifications.

BRIDGE BEAMS

At the beginning of the 2000s, the Precasting division was also equipped for the production of prefabricated beams for road and railway viaducts. Thanks to the development of new design solutions and significant production investments, we have been able to meet the specific needs of important Italian infrastructure projects, giving rise to high-performance elements and systems: high static performance with lights up to 40 meters, high compositional flexibility and speed in assembly times. Some clear examples of the use of our products are on the Milan-Bologna high-speed line, precisely in the Piacenza-Fontanellato-Modena section, and on the Treviglio-Brescia railway doubling. In addition, similar structural elements were used to create road bridges and decks covering the artificial tunnels on the Brebemi and Pedelombarda highway sections. The beams for the Milan-Verona railway line are currently in production.

PRECAST RINGS FOR
ARTIFICIAL TUNNELS

Our Precasting Division has designed and built a prefabricated system for the artificial tunnels of the Pedemontana Lombarda Highway. It is a system of 3 types of elements that are assembled on site to create a prefabricated closed box in concrete on which topsoil will be placed. Among the most interesting aspects in using this system for the construction of the highway, in addition to the undisputed speed of execution, there is the advantage of minimizing the environmental impact and overcoming the difficulties of traffic in one of the most built-up areas of Europe, with three quarters of the 87 km below ground level..

PRECAST RINGS FOR LINING
NATURAL TUNNELS

In 2023, Pizzarotti Precasting inaugurated the production of prefabricated segments for the construction of the lining rings of the Florence railway link, a work of strategic importance in the plan to strengthen the national railway network. The lining rings are composed of seven components. A special prefabricated element (invert) is also laid inside each ring, on which the railway armament is built. The prefabricated units are transported to the construction site by train.
