Welcome to PSI Fibers

We are manufacturers of a complete line of synthetic fibers specifically engineered for use as secondary reinforcement in ready mix concrete and cement-based building products.

PSI Fibers were first introduced into the concrete industry in 1999 along with our unique BulletPAC bags and AutOBatcher Fiber Dispensers. Our products were developed by individuals with decades of experience in concrete, synthetic fiber reinforcement, and fiber packaging technology.

Our products include Monofilament Fibers, Fibrillated Fibers, Multi-Mix 80 MicroFibers, and our MaxTen High Performance MacroFibers. All of these engineered fibers have been designed to meet specific applications and demands of the concrete specifier. Our fibers provide a very high level of secondary reinforcement. This secondary reinforcement system effectively reduces the formation of all types of early age cracking, thus protecting the concrete when its tensile strength is at its lowest. PSI Fibers allow for a very rapid and uniform distribution throughout the entire concrete matrix, which ultimately contributes to better performance and finishing of the concrete. PSI Flbers meet the material specifications described in ASTM C-1116, Type III, Section 4.1.3 "Synthetic Fiber-Reinforced Concrete and Shotcrete."

PSI Fibers and our innovative Packaging System will simply and surely give you the very best concrete fiber available to enable your concrete to develop its long-term durability.

Thank you for taking the time to discover the many benefits of our PSI Family of Synthetic Fibers. Should you have any questions or require additional information, please do not hesitant to contact us at info@psiconcretefibers.com, or you can call us at our toll free number 1-800-858-5671.
