Composite reinforcements

Fibre-Reinforced Polymer (FRP) reinforcements involve bonding tensile composite reinforcements to the surface of structural members to increase their crack resistance and load bearing capacity. FRP reinforcements are often used for flexural strengthening of beams and slabs, shear strengthening of beams and confinement of columns.
Freyssinet has always developed proprietary systems to offer the highest level of performance and quality of work:

  • Bending strengthening of columns, walls, beams, slabs, etc.
  • Strengthening of beams to resist shear forces
  • Reinforcement of the bursting strength of water retaining structures
  • Improving the seismic resistance of buildings, tanks, etc.
  • Improving the bearing capacity of columns by confinement
  • Strengthening of steel structures to resist bending or fatigue, without welding.

FRP reinforcements can be used in conjunction with a fire protection system.

Composite reinforcement solutions

Externally bonded CFRP fabric reinforcements – FOREVA® TFC

Carbon fibre reinforced polymer fabric reinforcement systems consist of unidirectional or bidirectional carbon fabrics saturated and bonded to the substrate by impregnation with epoxy resins.
  • Application on flat
    and curves surfaces
  • Increased bending, shear
    and seismic resistance
  • Tested for long-term performance
  • All types of structures

Externally bonded CFRP laminate reinforcements – FOREVA® LFC

Prefabricated carbon fibre reinforced polymer laminates are bonded to the flat concrete surfaces of structural elements that require tensile or flexural strengthening.
  • Application on flat surfaces
  • Extremely high strength
    and stiffness
  • Do not rust or corrode
  • All types of structures

Embedded CFRP rod reinforcements – FOREVA® RFC

Prefabricated rods made of carbon fibre reinforced polymer are embedded in grooves in the concrete pavement and anchored with cement or resin-based mortar. These systems are widely used for flexural strengthening.
  • Embedded in the concrete cover
  • Extremely high strength and stiffness
  • Do not rust or corrode
  • All types of structures

Glass or Aramid FRP fabric protections

Glass and Aramid fibre fabric systems consist of unidirectional or bidirectional fabrics and impregnated epoxy resins. GFRP systems are used to protect CFRP systems from harsh environmental conditions and AFRP systems are used to protect concrete elements from impact.
  • Protection against
    harsh environmental conditions
  • Protection against impacts
  • All types of structures
