Synthetic Fiber Blend Micro-Crack Inhibitor

Synthetic micro-crack inhibitor is a blend of polypropylene and polyvinyl alcohol micro-fibers engineered to provide three-dimensional crack control at multiple scales in concrete and mortar. The dual-fiber system simultaneously addresses plastic shrinkage cracking (PP fibers, 6–12 mm) and hardened-state micro-crack propagation (PVA fibers, 3–6 mm). Available as pre-blended packets for simple addition directly to the concrete mixer.
