Structural Strengthening of Buildings and Infrastructure using Carbon Fibre

The use of a building or civil engineering structure may change throughout the course of its service life, as for example its whole function can change, loads can increase and/or higher building standards are required and the structure must be made compliant. Sika provides fully comprehensive solutions with complete systems for all kinds of structural strengthening and improvement. Whether increasing the bending, shear or impact resistance, tested and proven Sika systems are available for use on reinforced concrete, steel, wood and masonry load-bearing structures.

Structural Strengthening Products and Systems

Column Flexural Strengthening

For externally bonded and near surface mounted (NSM) flexural strengthening of concrete, steel, timber, masonry and glass fiber structures.

Shear Strengthening of Beams

The shear capacity of reinforced concrete T-beams can be significantly increased by externally applied L-shaped CFRP profiles.

Column/Beams Strengthening

For structural column confinement, strengthening of weaker concrete, masonry, natural stone and timber structures.

Anchoring

Versatile end anchorage and NSM strengthening solutions.

Post Tensioned Strengthening

Active strengthening of structures as a replacement for damaged steel prestressing cables, seismic retrofitting, or for installation on cracked concrete surfaces.

Adhesives and Bonding

Multi-purpose structural epoxy resin based materials that reduce the working steps necessary for fast, easy and secure installation of SikaWrap® Fabric strengthening systems.

Crack Repair & Injection Resin

For sealing water bearing and dry cracks and joints, or creating a watertight curtain behind a structural envelope.

Carbon Fiber Reinforced Polymer (CFRP) plates

Prefabricated Carbon Fiber Reinforced Polymer (CFRP) plates

For strengthening of concrete substrates, prefabricated CFRP plates can be externally bonded or near surface-mounted. Sika offers a wide range of carbon FRP plates in different dimensions and varying E-moduli.

L-shape Carbon Fiber Reinforced Polymer (CFRP) plates

Shear capacity of concrete beams can be increased by externally applying CFRP strengthening systems. Sika provides unique L-shape CFRP plates for effective anchorage of stirrup forces in concrete compressive zones.

Carbon Fiber Reinforced Polymer (CFRP) post-tensioning systems

Post-tensioned systems are effective for control of structural cracks and deflections and to increase fatigue resistance and seismic resistance. Sika provides a unique system based on post-tensioned CFRP plates.
