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.
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.
