Between May and November 2012 Bauer successfully executed more than 7,000 sqm plastic concrete cut-off wall extending to a depth of 93 m. Here, the two Bauer BC 40 cutter units had to cut through very large hard rock boulders. In co-operation with our client Larsen&Toubro Limited the modern pre-grouting and trench cutter equipment was operated by a team of Indian and international specialists.
