Extending land out to sea creates new areas for development and limits the impact of climate change on coastlines.

World-class expertise
From Monaco to Hong Kong, we have delivered high-profile land-reclamation projects that reflect our technical expertise.
Our expertise
Safety and sustainability at sea
Our engineers design structures that can withstand waves, tides and storms. Their design work incorporates long-term performance, safety and environmental factors.
On the Beirut waterfront, for example, the shoreline is protected from nine-metre waves by eighty wave-absorbing caissons and an innovative wave-trapping system.
Proven offshore methods
From giant caissons to riprap-reinforced dykes and from gabions to breakwaters, we deploy nautical and industrial resources suited to the context.
Learn about the Monaco land reclamation project, with the manufacture and installation of 18 caissons built in the Marco Polo floating dock and placed offshore to protect the new eco-neighbourhood.

Innovating to create new offshore space
Innovation is at the heart of our land-reclamation projects, from designing more resilient dykes to developing next-generation anti-overwash systems and advanced technical solutions to manage wave energy more effectively.
In Beirut, the integration of wave traps effectively reduced overwash, while in Monaco, double-walled porous chambers were responsible for improved wave absorption.
Preserving marine biodiversity
Eco-design is also a key focus for us, and we apply it throughout every phase of our projects. This involves incorporating features from the outset that support biodiversity and reduce the impact of structures on marine ecosystems.
In practice, this includes eco-reefs, roughened surfaces and artificial modules that provide habitats for marine flora and fauna.
The Brest project illustrates this approach, with an enclosure dyke designed to retain water at low tide and create conditions favourable to ecological regeneration. Such measures demonstrate that technical performance, safety and environmental protection are fully compatible.
