Sika® CarboDur® BC 8

8 mm pultruded carbon fibre rod for near-surface-mounted (NSM) structural strengthening

Sika® CarboDur® BC 8 is a pultruded, carbon fibre-reinforced polymer (CFRP), circular rod. It is used for near-surface-mounted (NSM) structural strengthening of concrete, timber and masonry. The rod is bonded and fully encapsulated into surface slots using a Sika structural adhesive which is selected based on the design, application and environmental conditions. The rod is part of the Sika CarboDur® system.

  • Non-corroding
  • Very high strength
  • Invisible when installed
  • Good durability and fatigue resistance
  • Lightweight, very easy to transport and install
  • Easy to cut to the required length
  • Smooth surface without exposed fibres
  • Strengthened surface can be trafficked
  • No surface preparation or levelling of uneven substrates required
  • Improved resistance to fire (compared with externally bonded reinforcement)

Usage

Sika® CarboDur® BC 8 is used as a reinforcement rod for near-surface-mounted, bonded structural strengthening systems on concrete, masonry and wooden substrates Near-surface-mounted, bonded structural strengthening systems are used for:
  • Increasing the flexural loading capacity of elements and structures
  • Enhancing the load-carrying capacity or ductility of structural members
  • Replacing missing steel reinforcement
  • Structural upgrading of weak concrete elements or structures
  • Improving impact resistance
  • Passive strengthening for seismic event protection
  • Changing the structural system (removal of floor or wall sections)
 
  • Improving fatigue resistance
  • Reducing the stress on steel reinforcement
  • Repairing structural elements after damage (vehicle impact, fire, earthquake)
  • Stabilising vibrating structures
  • Anchoring SikaWrap® fabrics
  • Dowelling structural connections
Please note:
  • A specialist structural engineer must be consulted for any structural strengthening design calculation.
