Fiber-Reinforced Concrete by Legacy General Contractor
FIBER-REINFORCED CONCRETE — STEEL & SYNTHETIC FIBERS FOR ENHANCED PERFORMANCE
Fiber-reinforced concrete incorporates steel or synthetic fibers directly into the mix for distributed reinforcement throughout the slab. Steel fiber concrete provides exceptional impact resistance and is ideal for industrial slabs, heavy equipment pads, and heavy-duty floors. Synthetic fiber concrete reduces plastic shrinkage cracking and is used in residential and commercial slabs where enhanced durability is needed without traditional rebar or wire mesh.

Learn More5 Highlights on Fiber-Reinforced Concrete
Steel fiber concrete
exceptional impact resistance for industrial slabs, heavy equipment pads, and heavy-duty floors.
Synthetic fiber concrete
reduces plastic shrinkage cracking in residential and commercial slabs without rebar.
Distributed reinforcement
fibers throughout the entire slab provide uniform crack resistance vs. point reinforcement from rebar.
Eliminates rebar placement time
fiber reinforcement is mixed directly into the concrete at the batch plant.
Why Choose Our Fiber-Reinforced Concrete
Fiber reinforcement isn't a universal replacement for rebar — it's an enhancement for specific applications. We recommend the right fiber type and dosage for your project.
Steel fibers are ideal for industrial floors where impact and fatigue resistance are critical. Synthetic fibers are best for shrinkage crack control in standard flatwork.
Signs You Need Fiber-Reinforced Concrete
1. Industrial floor with heavy impact loads
Steel fiber concrete resists impact from dropped objects, heavy equipment, and repeated loading better than standard reinforced concrete.
2. Want to reduce shrinkage cracking
Synthetic fiber concrete reduces early-age plastic shrinkage cracking, resulting in a cleaner-looking finished slab.
3. Tight construction schedule
Fiber reinforcement eliminates the time needed to place rebar or wire mesh, speeding up the pour process.
Our Fiber-Reinforced Concrete Process
Step 1 — Fiber Selection
Choose steel or synthetic fibers based on application requirements. Determine dosage rate.
Step 2 — Mix Design
Fibers are added at the batch plant and mixed into the concrete for uniform distribution.
Step 3 — Placement & Finishing
Pour and finish normally. Fibers distribute throughout the slab during placement.
Step 4 — Curing
Standard curing procedures apply. Fibers do not affect curing requirements.

FAQs About Fiber-Reinforced Concrete
Do fibers replace rebar?
For shrinkage crack control, synthetic fibers can replace welded wire mesh in many residential applications. For structural reinforcement, steel fibers can supplement but rarely fully replace rebar. Consult engineering specifications.
Do fibers stick up on the finished surface?
Synthetic fibers are not visible on a properly finished surface. Steel fibers may occasionally show at the surface in a broomed finish but are not visible in troweled or polished finishes.
