Improving flood prevention in France
The France Digues (France Dykes) association has recorded more than 6000 km of dykes in France. ArcelorMittal's steel solutions are regularly selected for dyke extensions and reinforcement projects.
Dyke reinforcement in St-Laurent-du-Var
The Flood Risk Prevention Plan (PPRI) for the lower valley of the Var River highlighted the need to review the flood defences of the town of Saint-Laurent-du-Var. This resulted in a revision of the Flood Prevention Action Programme (PAPI) to include works which will protect an additional 1100 linear metres of the dyke. The work will protect nearly 2000 inhabitants, a small business area, sports and cultural facilities, and the town centre.
Reinforcement of the Saint-Laurent-du-Var dyke affects both banks. The work, which is bordered by metropolitan route 95, covers a linear distance of 1.6 km.
The reinforcement uses a double wall of sheet piles for sections of the embankment with sufficient distance between the road and the dyke. AZ 23-800 sections in lengths ranging from 12.7 to 14.5 m are being used for the main retaining wall. AZ 18-800 sections in lengths from 2.5 to 7.5 m are being used for the anchoring wall. The steel grade being used is S355 GP with a total weight of 2315 tonnes.
Rehabilitation of the Fouchy dykes in Troyes²
At the heart of Troyes metropolitan area is a network of canals running for around 130 linear kilometres. The presence of the canals makes the area a ‘little Venice’. A project to rehabilitate the Fouchy dykes protecting Troyes was launched following a safety assessment carried out in 2011. The rehabilitation of the dykes is one of the latest phases to be implemented. The project included the use of ArcelorMittal's HZ®/AZ® combined wall system.
Setec Hydratec and GEOTEC, the project's designers, chose ArcelorMittal’s sheet pile solution for sections where a 2H/1V embankment would excessively encroach on the river's hydraulic section. The VINCI Construction and LEDUC TP consortium proposed and implemented modern, high-performance sheet piles using 800-mm-wide AZ 18-800 sections to form self-stabilising curtain piles. The solution has proven to be both optimal and economical while meeting the demands of the Fouchy dam. To limit deformation of the highest parts, the consortium installed a curtain composed of HZ®-M profiles. This material gives the screen the necessary inertia to limit its deformation.
The AZ 18-800 sheet piles and HZ-M sections were manufactured in Luxembourg from 100% recycled steel. This limited emissions from transport and the overall environmental impact of the project.

Flood control systems
Floods are the most common and most costly natural disasters in the world. Floods are usually caused by heavy rainfall, storm surges, or rapid snow melt and are becoming more frequent due to climate change. Their devastating effects not only endanger the lives of humans and animals but also cause significant environmental and economic damage.
As flood risk is expected to increase in the coming decades, efficient flood control systems are evermore important to protect our lives and surroundings, keeping damage to a minimum.
The most common flood protection measures have always been dykes, typically made from soil. However, growing vegetation and erosion can cause them to weaken and fail over time making reinforcement or rebuilding necessary.
Useful information:
MoreSteel is gaining importance in the construction of modern flood control systems. In the form of sheet piles, steel can be used in a variety of ways for flood defence systems or bank protection. Steel sheet piles are one of the most efficient forms of protection against flooding and rising sea levels. They offer a number of advantages, such as ensuring watertightness, providing support, and stabilising new embankments or strengthening existing ones.
Steel sheet piles require less space, equipment, and manpower and can be installed quickly with guaranteed quality – even in remote locations. Sheet piles are ideal for temporary flood protection systems as they can be easily removed and 100% recycled.
Sheet pile protection can also be combined with floodgates and locks to facilitate water traffic.
