In the south-east of France, Freyssinet has completed its maintenance and sealing work on the Mesches Dam. The 100-year-old dam, which is located at an altitude of 1,400 metres, supplies electricity to 50,000 people in the Roya valley every day.
At EDF's request, the Freyssinet teams have repointed the stonework over an area of 1,400 m² to seal the upper part of the upstream face, and applied a 1,800-m² shotcrete facing on the lower part of the dam.
Built in 1917, the dam is one of the most important structures enabling the generation of hydroelectric power in the Alpes-Maritimes region. At 65 metres high, 1.2 million cubic metres of water pass through it each day.
