Application

Sika® CarboDur® systems are used to improve, increase or repair the performance and resistance of structures for:

Increased load carrying capacity:

  • Increasing the load capacity of floor slabs, beams and bridge sections.
  • For the installation of heavier machinery.
  • To stabilise vibrating structures.
  • For changes in building use.

Damage to structural elements due to:

  • Deterioration of the original construction materials.
  • Steel reinforcement corrosion.
  • Accidents (Vehicle impact, earthquakes, fire).

Improvement of serviceability and durability:

  • Reduced deflection and crack width.
  • Stress reduction in the steel reinforcement.
  • Improved fatigue resistance.

Change of the structural system:

  • Removal of walls and/ or columns.
  • Removal of floor and wall sections to create access/ openings.

Resistance to possible events:

  • Increased resistance to earthquakes, impact or explosion etc.

To repair design or construction defects such as:

  • Insufficient/ inadequate reinforcement.
  • Insufficient/ inadequate structural depth.

Description

Sika® CarboDur® plates are pultruded carbon fibre reinforced polymer (CFRP) laminates, designed for strengthening concrete, timber, masonry, steel and fibre reinforced polymer structures.

Sika® CarboDur® plates are bonded onto the structure as externally bonded reinforcement using Sikadur®-30 epoxy resin based adhesive for normal temperatures during application and/ or service.

Features and benefits:

Non-corroding.

  • Very high strength (CarboDur® S) or combination of very high strength and high stiffness (CarboDur® M).
  • Excellent durability and fatigue resistance.
  • Unlimited lengths, no joints required.
  • Low system thickness, simple execution of plate intersections or crossings.
  • Easy transportation (rolls).
  • Lightweight, very easy to install, especially overhead (without temporary support).
  • Minimum preparation of plate, applicable in several layers.
  • Smooth edges without exposed fibres as result of production by pultrusion.
  • Extensive testing and approvals available from many countries worldwide.
