Two-component 100% solids, moisture tolerant, high strength, high modulus epoxies for use with SikaWrap and Carbodur FRP systems

common reasons for structural strengthening:
  •  Durability problems due to poor or inappropriate construction materials
  • Inadequate design or construction
  • Aggressive environments not properly understood during the design stages
  • Increased loading requirements due to changes of policy or use of structures
  • Increased life-span requirements made on ageing infrastructure
  • Exceptional or accidental loading
Structural Strengthening Systems


Fiber Reinforced Polymers

Fiber reinforced polymers (FRP) are a proven technology for upgrading and strengthening concrete, masonry, and steel structures. These advanced composite materials have exceptionally high strengths, yet are very lightweight and easy to work with. They are used for increasing the capacity of existing buildings, seismically upgrading structures, correcting design or construction errors, and allowing modifications or changes in use.

  • Economical and durable
  • Easy application
  • Extremely high tensile strength
  • Outstanding fatigue behavior
  • Absolute corrosion resistance
  • Ability to upgrade structure while in use
  • Upgrades possible even with limited access
Sika CarboDur® and SikaWrap® Systems

Sika CarboDur plates and SikaWrap fabrics have been used successfully on thousands of projects worldwide. The most common uses have been for flexural strengthening, shear upgrades and column confinement. However, they have many other uses, including strengthening for cut-outs, blast hardening, fire and structural damage, and upgrading structures damaged by corrosion.
