Structural Strengthening

Structural Strengthening

Efficient strengthening of concrete structures can be applied by using fibre reinforced polymer (FRP), which are available in prefabricated plates, fabrics as well as post-tensioned systems.
Sika provide a full range of strengthening systems consist of different type of materials which can be used for flexural, shear and axial strengthening as well as for increasing seismic resistance of structures.

Prefabricated CFRP Plates

For strengthening of concrete substrates, prefabricated Carbon Fibre Reinforced Polymer (CFRP) plates can be bonded on top of surface. Sika offers a wide range of CFRP plates in different dimensions an E-modulus.

FRP Fabrics

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

CFRP Post-tensioning Systems

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