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.

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.
