Structural Strengthening

To extend the longevity of the structure for many decades to come, structural strengthening is a safe, secure choice. Sika provides fully comprehensive, complete systems for all kinds of structural strengthening. Whether the requirement is to increase the bending, shear or seismic resistance, tested and proven Sika systems are available for use on reinforced concrete, steel, wood and masonry load-bearing structures.

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 LP IN epoxy resin based adhesive for elevated temperatures during application and / or service.
Please refer to the respective Product Data Sheet for more detailed information about adhesives.
Sika® CarboDur® S may only be used by experienced
professionals.
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.
