Sika® CarboDur® S
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.

- 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.
- Deterioration of the original construction materials.
- Steel reinforcement corrosion.
- Accidents (vehicle impact, earthquakes, fire).
- Reduced deflection and crack width.
- Stress reduction in the steel reinforcement.
- Improved fatigue resistance.
- Removal of walls and/or columns.
- Removal of floor and wall sections to create access/openings.
- Increased resistance to earthquakes, impact or explosion, etc.
- Insufficient/inadequate reinforcement.
- Insufficient/inadequate structural depth.

Application
Consumption
Width of Sika® CarboDur® S plate | Typical consumption of Sikadur®-30* |
50 mm | 0.20 − 0.28 kg/m |
80 mm | 0.32 − 0.44 kg/m |
100 mm | 0.44 − 0.64 kg/m |
150 mm | 0.68 − 1.00 kg/m |
*Note: Consumption is for standard application only. Rough or uneven substrate surfaces, plate crossings, loss and wastage can lead to a higher adhesive consumption of up to 20 %.
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.
