Plexus™ Synthetic Macrofibers are uniquely engineered for slab-on-ground and precast applications with higher tensile strength to provide better “Built-In Reinforcement” as a replacement for steel fibers, welded-wire fabric (WWF) and conventional reinforcing bars in a variety of secondary reinforcement applications. In addition, Plexus™ Fibers help to minimize temperature shrinkage cracking, plastic settlement and plastic shrinkage cracking. Plexus™ Fibers distribute uniformly throughout the concrete matrix and deliver excellent finish-ability.
