Bauer completes cut-off wall construction in Mauritius

23 June 2015

Bauer Spezialtiefbau GmbH has announced it has completed construction of the cut-off wall for the EUR 35 million Bagatelle Dam Project in Mauritius.

The last panel of the wall was constructed on 9 May, almost a year after work commenced on the project.

As part of its work, Bauer Spezialtiefbau constructed a 2.4km long diaphragm cut-off wall (56,781m2), socketed into rock. The soil partially consists of very hard basalt - about 20,000m2 of slightly to moderately weathered basalt had to be penetrated over the entire structure for the new dam. In the central dam area, heavy layers of basalt, up to 28m deep, were removed in order to construct the cut-off wall with the specified depth. Three duty cycle cranes of the type MC 96 and MC 128 with a BC 40 trench cutter, as well as two grabs, were used.

The project is being developed for The Ministry of Energy and Public Utilities of Mauritius, with China International Water & Electric Corp as main contractor.
