Using KraTos™ Macro synthetic fiber reinforcement in shotcrete instead of wire mesh may help to shorten the project time by up to 40% depending on the surface class. Placing wire mesh in a tunnel is a challenging work that may lead to accidents. As the surface gaps are heterogeneous, the wire mesh may not be laid out so as to cover the concrete evenly, which results in 50% more shotcrete use and faulty applications. Using shotcrete reinforcement with non-corrosive KraTos™ Macro fibers improves work safety, extends durability and saves time and money for the project.
