Reinforcing the shotcrete with Macro Concrete instead of mesh steel provides the project with a time advantage of up to 40% depending on the floor classes. Wire mesh bonding in tunnels is very difficult and is a work that causes work accidents. Since the floor openings are not homogeneous, the inability to place the mesh steel on the floor with equal spacers causes both the use of shotcrete of more than 50% and incorrect applications. The application of shotcrete reinforced with Macro Beton fibers increases work safety, its stainless structure provides high durability, and it provides time and cost advantages to the project.
