Our case studies

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.

After one of the post-tensioned floors in a multi-storey car park in Takoma Park sagged without warning, repairs had to be rapidly executed with minimum impact on the garage users.

Design and installation of base isolation measures for a hospital in Turkey had to address the fact that the building was made up of sixteen blocks, all of varying heights and dimensions.

Works to install cathodic protection and repair a concrete wharf that carries pipelines transferring fuel from ships to land must be tightly managed so its operation is not impacted.

As part of its asset management strategy, the Moroccan National Railways Office launched a programme to restore several engineered structures along the railway line between Tangiers and Sidi Kacem. Structural strengthening of the Hjar Ennhal bridge was a true challenge.

To fight its deterioration over time, a balanced cantilever box girder bridge in regional New South Wales was reinforced for additional load capacity using post-tensioning, and repaired under traffic in a complex and carefully managed procedure.

Repairs to the concrete deck of one of the world’s busiest container terminals in the Philippines had to be scheduled to suit both the port’s daily operations and the tide tables.

A specially developed mix and custom-designed equipment now allow ultra-high-performance fibre-reinforced concrete to be spray-applied, opening up a world of possibilities for this durable material.
