IMI delivers fiber admixtures in our concrete. Fibers are integrally mixed in your concrete to provide three dimensional crack controls. Concrete fibers vary in length, thickness and fiber count. Talk to your local IMI sales representative to discuss your particular job and to determine the type and amount of fiber needed.
