Since concrete structures are often exposed to different aggressive environments, they require high quality protection systems. Years of research plus decades of practical experience have enabled Sika to develop a fully comprehensive solution to restore, rehabilitate and protect concrete structures.

London Underground Tunnel

London, United Kingdom
2013
The London Underground, commonly known as “the Tube,” is the oldest, and still the second-largest, subway system in the world. At Embankment station, two tunnel tubes run at different depths. The uppermost tunnel was constructed using the cut-and-cover method: a large trench was first excavated and then roofed over. The cast-iron tunnel ceiling beams, which carry the full weight of the structures above, date from 1870 and now, some 140 years later, were urgently in need of renewal to enhance safety. Strengthening of over 90 cast iron beams was completed with Sika® CarboDur® UHM carbon-fiber-reinforced polymer (CFRP) system.

The Rialto Bridge

Venice, Italy
2017
Designed by Antonio da Ponte and completed after three years in 1591, the Rialto Bridge is one of the most well-known bridges in the world and is certainly the most famous bridge in Venice (Italy). During the building of the bridge, many believed the project was too audacious from the engineering point of view, yet the bridge is still standing and has become one of the architectural icons of the city of Venice. Sika was involved in the restoration, maintenance and overall refurbishment of the Rialto Bridge, preserving the architectural nature of the original materials and applying non-invasive but efficient structural solutions as well as to stop the decay of its structure and materials.
