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 [...]
