Our case studies

Conventional solutions for strengthening a critical viaduct in west London proved impractical and led to the development of a ‘plug and play’ post-tensioning system and bespoke erection equipment.

After more than 10 years of service, an assessment by Doncaster Council indicated that carriageway refurbishment and essential safety repairs were required for expansion joint replacement.

As part of a major port development project in Melbourne, Freyssinet has been awarded the dock restoration of the Webb Dock port facility.

To prevent corrosion on a 1,100-metre long structure, Freyssinet's teams installed a large-scale Impressed Current Cathodic Protection system (ICCP).

Featuring a combined concrete and masonry structure, the Sahasinaka viaduct was built in 1934. As one of the pier foundations showed signs of subsidence, structural strengthening of the bridge was conducted by Freyssinet.

Extending the lifespan of the viaduct by 100 years is what Freyssinet achieved after proposing a turnkey service to conduct heavy retrofitting works including additional prestressing, and completing them ahead of schedule.

Structural strengthening works were needed to renovate the ageing prestressed concrete preheater tower of a plant to increase its bearing capacity before installation of new equipment.

A world first was implemented by Freyssinet and its partners to increase the traffic capacity of the Rande cable-stayed bridge. It consisted in connecting an additional steel deck on both sides of the existing one and supporting it with a new stay cable system.

Freyssinet's teams were enlisted to strengthen the deck, execute the 23 pairs of high-tech stay cables replacement and maintain structural fittings.
