The Grand Port Maritime de La Réunion handles 99% of the island’s external trade. The port authorities decided in 2014 to increase its berthing and ofloading capacity by deepening the existing basin, lengthening the quay and installing additional gantries.

As part of a joint venture, Soletanche Bachy carried out the foundation and civil engineering works. These were divided into two completely separate design sections: underpinning the quay to deepen the basin, and building a quay wall to lengthen the existing quay.

The work presented numerous dificulties (technical, environmental, organisational) for which Soletanche Bachy provided suitable solutions.
