Menard has been working on re-routing the D930 secondary road as part of the project to modernise the Serqueux-Gisors SNCF line. Context Modernisation of the railway line connecting the towns of Serqueux and Gisors in Normandy will eventually allow the development of rail freight in the region and relieve congestion on the Le Havre-Rouen-Paris [...]

Perform an anti-liquefaction mitigation treatment In Fos-sur-Mer, for the construction of a liquefied natural gas complex, Menard performed an anti-liquefaction mitigation treatment for the dock by increasing the embankment’s density using compaction grouting technique. This was an innovative operation as the equipment used for this technique was the Controlled Modulus Columns equipment which led [...]

Compaction grouting under railway backfills As part of the construction of the Bretagne - Pays de Loire high-speed line, Menard was requested to stabilise the ground under the railway backfill. A drilling campaign showed that the area to be treated was made of fossilised karst filled with sand, which made the ground extremely loose [...]

Largest ground improvement project in France At the end of 2015, an LNG terminal with an annual regasification capacity of 13 billion cu. metres opened in the Port of Dunkirk. In early 2012, the consortium, that included Menard, was awarded the port development works. The project consisted in building the dock to receive the [...]

"Stand-down" operation for the reinforcement of the Freycinet 8 quay The project aimed to reinforce the quay under the crane circulation area used to unload wind turbine from boats. The 6,500 sq. metre area, composed of loose and dense sand down to 5 m, had to be executed in less than 3 weeks. Menard’s [...]

Work with short deadlines Menard has been chosen for the « bulk excavation and ground improvement works » as part of the Aubagne LRT maintenance centre. In order to improve the soil in place, made of gravelly backfilling materials and sandy silts, Menard used the stone columns technique. Made of calcareous material, these columns does [...]

Foundations of one of the most heavily loaded railways in the world For the foundations of one of the most heavily loaded railways in the world (2,000 tons of the space rocket), Menard developed an alternate solution combining dynamic replacement and vertical drains as an alternative to excavation and replacement of the mangrove, a [...]

Iconic project : Nice airport, France Deepest dynamic compaction application (27 m, 4,000 tm energy) on the Nice airport, France project The 'giga-machine' was designed and custom-built for this site The challenge was to compact 20,000,000 m³ of land reclamation while maintaining air traffic. The 'giga-machine' was designed and custom-built for this job. The [...]

Soil expertise serving high-speed rail The largest project of its type in Europe, the South Europe Atlantic high-speed line will reduce travel time between Paris and Bordeaux. Menard improved the ground under the backfill over a height of 5 to 10 metres for the northern and southern access to one of the project’s iconic [...]
