What the steel fiber industry said could not happen is happening. The first segmentally lined tunnel project is underway in the North America with segments being produced as we post this. More information will follow on the specifics of the project but we can report that the dose rate is 7 kg/m3 of Barchip BC54 fiber. Non corrosive, easy handling, less wear on equipment, less weight, easy to finish, lower co2 emissions, and cost effective.
