The expertise acquired in concrete prefabrication has led Crezza to specialize in the production of precast reinforced concrete segments, used in the construction of road tunnels and railway tunnels, with significant cost and time savings compared to traditional metal formwork.
Crezza handles the prefabrication, supply, and installation of:
- self-supporting circular-section segments for the lining of underground tunnels, widened sections, main sections, bypasses, lay-bys, or emergency lanes in tunnels;
- circular-section segments for the construction of artificial tunnels, used as lost formwork, including with flute-shaped entrances;
- structural segments for the construction of artificial tunnels with polycentric sections or constant-radius sections.
The high quality of the materials used, the prefabrication and the assembly guarantees an excellent face effect, the highest safety standards and high durability.
