Microstran Synthetic Micro-Fiber is the ONLY micro-fiber available in the industry that produces exceptionally high plastic shrinkage crack reduction (consistently >90%), and is an excellent alternative for WWM when used as secondary reinforcement. (Exceeding the requirements of ICC-ES AC32 4.7)

Durastran^® Synthetic Macro-Fiber is a highly engineered Fiber, designed to enhance the concrete’s toughness, and as a replacement for welded wire reinforcement and conventional steel bars when used as secondary reinforcement; to absorb the energy and stress from shrinkage and macro cracking.

The Durastran^® Fibers provide effective tight crack control, increasing the concrete structure’s long-term durability and performance through flexural and tensile strength improvements.

Durastran^®HB Synthetic Hybrid Fiber Blend is a select combination of industry leading Fibers, brought together in a single dosage to provide a Total Crack Management System.

The Micro-Fibers help to manage the stress from millions of micro-cracks that typically form during the first 24 hours. The Micro-Fibers are uniquely designed to chemically bond with the concrete paste, and arrest those forming cracks, helping to keep them from propagating.

The Macro-Fibers are engineered to enhance the concrete’s toughness, as a field-proven replacement for WWR and conventional steel bars when used as secondary reinforcement. They are designed to carry post-crack stress and load beyond the plain concrete’s originally designed capability.

Durastran^®4X Synthetic Macro Fiber Blend is an industry exclusive macro-fiber with an ultra-high fiber yield. Its unique design delivers performance through every phase of the concrete’s curing and long-term drying process. Durastran^®4X is an excellent replacement for conventional (secondary) steel reinforcement; as a crack management system with excellent finishability.
