Sika® CarboDur® S

Pultruded Carbon Fibre Plates for Structural Strengthening as Part of the Sika® CarboDur® System

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.
Please refer to the relevant Product Data Sheet(s) for more detailed information about each of these adhesives.

  • Non-corroding.
  • Very high strength.
  • 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.

Usage

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.

Application steps

SUBSTRATE QUALITY

Sika® CarboDur® plates externally bonded to the concrete surface
Recommended minimum concrete pull-off strength after surface preparation:

  • Mean: 2.0 N/mm2
  • Minimum: 1.5 N/mm2

The effective concrete pull-off strength after surface preparation has to be verified.
If concrete pull-off strength is below the stated minimum requirements, alternative Sika solutions are available:

  • CarboDur® applied in slots as near surface mounted (NSM) reinforcement.
  • SikaWrap® fabrics: Please refer to the Product Data Sheet for the SikaWrap® fabrics.

Concrete must generally be older than 28 days (dependent on curing conditions and the type of concrete etc.).

 
Sika® CarboDur® externally bonded to other substrates
For application of CarboDur® plates to all other substrates (brick, stone, steel, wood, fibre reinforced polymer, etc.)  refer to the “Technical Information Manual for Sika® CarboDur® Externally Bonded Reinforcement” Ref: 850 41 05. Contact Sika Technical Service for detailed advice.

SUBSTRATE PREPARATION

Concrete must be cleaned and prepared to achieve a laitance and contaminant free, open textured surface.
Refer to the “Technical Information Manual for Sika® CarboDur® Externally Bonded Reinforcement” Ref: 850 41 05.
