Micro-Fiber Reinforced Concrete
MICRO-FIBER REINFORCED CONCRETE
Micro-fiber reinforced concrete uses short (3/4" to 1-1/2") polypropylene, nylon, or polyester fibers added to the concrete mix to reduce plastic shrinkage cracking during the critical early curing period. Micro-fibers distribute throughout the mix at millions of fibers per cubic yard, creating a three-dimensional reinforcement network. Standard addition for residential and commercial flatwork, slabs-on-grade, shotcrete, and precast.
Key Highlights
Shrinkage crack control
millions of micro-fibers reduce plastic shrinkage cracking during early curing.
Easy addition
fibers are added at the batch plant and mix uniformly throughout the concrete.
Standard practice
micro-fibers are now standard in most residential and commercial flatwork.
Why Choose Our Micro-Fiber Reinforced Concrete
Micro-fiber reinforcement has become standard practice for quality concrete work. We specify polypropylene or nylon micro-fibers in most flatwork mixes to reduce plastic shrinkage cracking — the fine surface cracking that occurs during the first 24 hours as concrete cures. Micro-fibers supplement (don't replace) structural reinforcement like rebar and wire mesh.

FAQs About Micro-Fiber Reinforced Concrete
Do micro-fibers replace wire mesh?
No. Micro-fibers reduce plastic shrinkage cracking (early age, surface) but do not provide structural reinforcement. Wire mesh or rebar provides structural capacity and controls long-term cracking after the concrete has hardened. Both should be used for best performance.
