No other civil engineering company in Berlin has such a wealth of experience in underwater excavation as BTB. With large excavators of up to 100 tonnes, floating dredgers and suction dredgers we can dig pit depths down to 30 meters. Our dredgers are equipped with GPS, meaning that a precise earth excavation is possible under the most difficult of conditions. Our international team of specialists has been entrusted with underwater excavation in large projects such as the connection of the S21 to Berlin central train station or the new construction of the A100 in Berlin-Treptow.
