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.

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.
