Sika® CarboDur® M
Sika® CarboDur® M plates are pultruded carbon fibre reinforced polymer (CFRP) laminates, designed for strengthening concrete, timber, masonry, steel and fibre reinforced polymer structures.
Sika® CarboDur® M 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 for more detailed information about each of these adhesives.
- Combination of very high strength and high stiffness
- Non-corroding
- 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
- 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® M plate | Typical consumption of Sikadur®-30* |
60 mm | 0.24 − 0.32 kg/m |
90 mm | 0.40 − 0.56 kg/m |
100 mm | 0.44 − 0.64 kg/m |
120 mm | 0.45 − 0.80 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: 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.
