The Eurasia Tunnel Project will be constructed between the district of Göztepe, on the Asian side of Istanbul, with Kazliçeşme, on the European side. The 14.6 km project length will incorporate 5. 4 km of twin deck tunnel and 9.2 km of road improvement works. The twin deck tunnel portion will cross beneath the Bosphorus Strait and will be the first road tunnel to link the European and Asian sides of Turkey.

A Herrenknecht mix-shield TBM will be used to bore 3.4 km of tunnel. At 13.7 m in diameter the machine ranks as the 6th largest in the world. At its deepest point it will be 106 m below sea level generating a mix-shield machine record setting 11 bar of face pressure!

Team Mixing Technologies Inc. is privileged to be a part of one of the top engineering projects of the world and has recently supplied a reconditioned 25 m3/hr bi-component grout plant complete with new water weigh hopper, screw conveyors and grout pump.
