Carbon Fiber Fabric For Concrete Strengthening

External bonded reinforcement system specifically engineered to enhance the load-bearing capacity and durability of concrete structures.
40-100% Capacity increase
50+ years Service life

Carbon Fiber Fabric For Concrete Strengthening is a high-performance external reinforcement system designed to restore, upgrade, or enhance concrete structures. The fabric is bonded to concrete surfaces using structural epoxy adhesives, providing additional tensile capacity to beams, slabs, columns, and walls. The system increases flexural and shear strength, improves seismic performance, and extends service life. Available in unidirectional and bidirectional configurations with areal weights from 300 to 1200 g/m². The fabric meets the requirements of ACI 440.2R, FIB 14, and international strengthening codes. Ideal for parking structures, bridges, buildings, and infrastructure where increased load capacity is required.

Concrete Strengthening Applications

◈ Flexural strengthening Beams, slabs, girders — increases moment capacity
◈ Shear strengthening Beam webs, column joints — increases shear capacity
◈ Column confinement Circular or rectangular column wrapping
◈ Seismic retrofit Ductility and energy dissipation enhancement
◈ Crack repair Prevents crack propagation and water ingress
◈ Blast protection Increases structural resilience to impact

Concrete Strengthening Advantages

  • Increases load capacity without significant added weight
  • Thin profile — no change to structural dimensions
  • Corrosion-resistant — protects concrete from environmental damage
  • Rapid installation — minimal disruption to operations
  • Complies with ACI 440.2R and international codes
  • Cost-effective alternative to replacement

Installation Overview

1 Surface preparation — sandblast or grind concrete
2 Apply primer and putty to level surface
3 Apply structural epoxy adhesive (saturant)
4 Place fabric on the surface and saturate
5 Apply additional layers as required
6 Protective topcoat or fireproofing (if needed)

Frequently Asked Questions

Flexural capacity can increase by 30%–60%, shear capacity by 40%–80%, and column confinement can increase compressive strength by 40%–100%. The exact increase depends on the number of layers, existing reinforcement, and concrete condition.

Concrete surfaces must be sandblasted or ground to remove laitance, contaminants, and achieve a surface profile that provides a minimum tensile bond strength of 1.5 MPa. All cracks larger than 0.3 mm must be filled with structural epoxy.

Typically 1 to 4 layers are used. More layers provide additional capacity but may exceed the maximum reinforcement ratio limits defined in ACI 440.2R. Engineering design should specify the optimal number of layers.

Yes. Column wrapping increases ductility and energy dissipation, making it effective for seismic retrofitting. The system can also be used to strengthen shear walls and beam-column joints for improved seismic performance.
