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
To extend the longevity of the structure for many decades to come, structural strengthening is a safe, secure choice. Sika provides fully comprehensive, complete systems for all kinds of structural strengthening. Whether the requirement is to increase the bending, shear or seismic resistance, tested and proven Sika systems are available for use on reinforced concrete, steel, wood and masonry load-bearing structures.
