Watertight wall for a dam

Soletanche Bachy, a subsidiary of Soletanche Freyssinet (VINCI Construction), signed a contract on 9 December 2010 to build a sealing wall for the Subansiri dam, a 116 m-high, concrete gravity dam currently under construction in the state of Assam, in the north of the country.

The wall will be created using hydrofraise equipment, working from three tunnels, 7 metres high, located within the dam. It will be 800 mm thick and 50 metres deep.

Worth €11m, the works will start in May and take 12 months to complete.
