Structural Strengthening Methods
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.
