Réunion
Saint-Denis
Viaduct
2019

This offshore viaduct is built 70 meters from the coast.
It will stretch along the northwest coast of Reunion Island and will connect the island’s main city to the commercial port.
This 12,5 km new coastal highway comprises three main parts:
- One Interchange and many dykes
- The Coastal Viaduct of 5,4 km which rises 20 to 30 meters above sea level
- The Grand-Chaloupe Viaduct. The slightly curved deck is made up of XS3 environmental exposure class concrete, with added silica fume.

CHRYSO meets requirements through its EnviroMix® approach.
CHRYSO conducted several specific durability performance trials to meet the project specifications (which includes a concrete durability guarantee of 120 years minimum). CHRYSO also provided its client with the results along with recommendations on formulations and adequate admixtures solutions.

CHRYSO uses a combination of admixtures which provides unrivalled performance in terms of robustness, workability retention, pumping and durability.
