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

Fiber Reinforced Polymer (FRP) Fabrics

Fabric strengthening systems, also called fiber reinforced polymer (FRP) systems, consist of woven or stitched, unidirectional, carbon and glass fiber fabrics and impregnating resins. This unique combination makes this a multifunctional material for many applications including confinement, shear, and seismic upgrading and strengthening of weak concrete, masonry, natural stone and timber structures.

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.
