High-Performance Concrete Applications

Explore how Earth Fiber reinforcement systems eliminate conventional rebar cages, increase structural ductility, and speed up construction across major infrastructure sectors.

SECTOR 01: LOGISTICS & WAREHOUSING

Heavy Industrial Floors & Jointless Slabs

Modern distribution centers and manufacturing plants operate heavy Automated Guided Vehicles (AGVs) and reach trucks with intense point wheel loadings. Traditional welded mesh cannot reinforce near the surface where joint spalling occurs.

  • Recommended Fiber: Earth Fiber 50mm or 60mm Loose Hook End Steel Fiber
  • Typical Dosage: 20 to 30 kg/m³
  • Benefits: Allows joint spacing up to 35m, prevents edge chipping, and speeds pouring up to 2,000 m²/day using laser screeds.

SECTOR 02: UNDERGROUND INFRASTRUCTURE

Tunneling, Mining & Slope Stabilization

Fixing welded mesh against uneven rock contours in tunnels is dangerous and labor-intensive. Fiber-reinforced shotcrete (FRS) is sprayed directly onto freshly excavated rock, conforming intimately to every fissure.

  • Recommended Fiber: Earth Fiber 50mm Hook End (Loose / Glued) & Micro PP
  • Typical Dosage: 25 to 40 kg/m³ Steel Fiber + 0.9 kg/m³ PP
  • Benefits: Drastically reduces spray rebound, high energy absorption (ASTM C1550 / EN 14488-5), and protects workers immediately after excavation.

SECTOR 03: PRECAST & GRC CASTING

Precast Concrete Elements & GRC Facades

Manufacturing precast drainage culverts, manhole frames, acoustic highway barriers, and architectural GRC screens is made faster and lighter with fiber reinforcement.

  • Recommended Fiber: AR Crack Shield Glass Fiber, 50mm Crimped Steel Fiber
  • Typical Dosage: 0.6 - 1.2 kg/m³ AR Glass (or 2-3% in GRC premix)
  • Benefits: Eliminates rust staining on facade panels, reduces demoulding cycle time, and prevents chipped edges during transport and rigging.

SECTOR 04: TRANSPORTATION & PAVEMENTS

Highways, Airport Taxiways & White-Topping

Heavy axle loadings at highway toll plazas, bus rapid transit (BRT) stops, and airport parking aprons cause severe fatigue cracking in plain concrete. Earth Fiber distributes dynamic tire shock loads evenly across the pavement depth.

  • Recommended Fiber: 50mm Crimped Steel Fiber / White Polyester Fiber for Asphalt
  • Typical Dosage: 20 to 30 kg/m³ in PQC concrete; 2-3 kg/ton in hot mix asphalt
  • Benefits: Suppresses reflective cracking in overlays, increases rutting resistance, and extends roadway service life.
