Structural Strengthening

Strengthening Systems

Prefabricated CFRP Plates

The Sika CarboDur® System is the most established carbon fiber-reinforced polymer (CFRP) strengthening solution. It consists of Sika CarboDur® CFRP plates and rods, together with the structural epoxy resin based Sikadur® adhesives. This simple, tested and well proven, highly durable system has outstanding performance.

Unique pre-stressed strengthening system

Post-tensioning: a force is applied to create permanent stress in a structure, so that it can withstand load more efficiently or with less total deflection. In conventional post-tensioning, the load is put on steel tendons within the concrete structure. However, with the Sika CarboStress® system, the advantages of the Sika CarboDur® CFRP plates and post-tensioning techniques are combined to form a unique active external strengthening solution.

Unique L-shaped cfrp Plates/brackets

The shear capacity of concrete beams can be increased by the external applied Sika CarboShear L-shaped profiles.

  • Installation is fast and easy
  • Excellent anchorage is assured
  • No drilling through the top slab is required

FRP Fabrics

The SikaWrap® fabric strengthening system provides a wide range of solutions to meet different demands on many different types of projects. The installation is extremely flexible and accommodating of different surface planes and geometry, making this a very multifunctional material for many applications including:

  • Confinement
  • Shear strengthening
  • Seismic upgrading
  • Weak substrate strengthening
