Anti Corrosion Structural Strengthening

Anti Corrosion Structural Strengthening


Sika® CarboDur® S plates are pultruded carbon fibre reinforced polymer (CFRP) laminates, designed for strengthening concrete, timber, masonry, steel and fibre reinforced polymer structures.


  • Non-corroding
  • Very high strength
  • Excellent durability and fatigue resistance
  • Unlimited lengths, no joints required
  • Low system thickness, simple execution of plate in-tersections 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 manycountries worldwide


  1. 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
  2. Damage to structural elements due to:
    Deterioration of the original construction materials
    Steel reinforcement corrosion
    Accidents (Vehicle impact, earthquakes, fire)
  3. Improvement of serviceability and durability:
    Reduced deflection and crack width
    Stress reduction in the steel reinforcement
    Improved fatigue resistance
  4. Change of the structural system:
    Removal of walls and / or columns
    Removal of floor and wall sections to create access /
  5. Resistance to possible events:
    Increased resistance to earthquakes, impact or ex-plosion etc.
  6. To repair design or construction defects such as:
    Insufficient / inadequate reinforcement
    Insufficient / inadequate structural depth
