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.
Which fiber is right for you?
Fiber added to your concrete will help to control cracking. Cracking can occur for a variety of reasons. See the chart below to determine your usage and crack control options. Certain fiber types may not be stocked at all locations. Please call ahead.
