The use of a building or civil engineering structure may change throughout the course of its service life - for example, its function can change, loads can increase, or higher building standards become required and the structure must be made compliant. Historical or landmark structures may need to be reinforced in a discrete way without impacting the original design or forms.

Systems for all types of 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.

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.

Fiber Reinforced Polmer (FRP) fabrics

Externally applied fabrics can be used to increase flexural, shear, axial or seismic resistance of structures. Sika offers various fabric systems, based on different types of materials for specific needs and cost-optimized strengthening.
