Earthworks and special underground engineering

BTB belongs to the most competent civil engineering companies in Berlin.
For more than 30 years we have been playing a role in reshaping the infrastructure in the capital and in Brandenburg.

Earthworks

Our services range from the classic excavator works to construction site equipment and even special underground construction.

Excavation pits & pit lining

We have unique experience in excavating, securing and contouring extremely large and deep excavation pits.

Underwater excavations

We are the most experienced civil engineering company in Berlin for underwater excavations (with our own specialists).

Soil replacement

We implement soil replacement on soft or non-loadbearing substrates for a safe development.

Decontamination

We carefully remove any strongly contaminated soils and correctly dispose of them – often in our own specialised plant.

Site preparation

Whether it is a railway embankment or a construction site – we prepare the substrates for development thanks to GPS and laser technology.

SPECIAL UNDERGROUND ENGINEERING WITH FLOATING DREDGERS & SUCTION DREDGERS

No. 1 in underwater excavation

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.

EXTRACTION OF FINE SAND & DUMPING AREA FOR RUBBLE

Opencast mine in Knoblauch Kapellberg Ketzin

With the takeover of the company K.S.E. in 1999 we were able to integrate our own opencast mine into our corporate group. Here, 1.5 million tonnes of fine sand are waiting for extraction. This sand can be processed as aggregate for building materials to plaster sand or even to certified playground sand.

 

At the same time our open-cast mine provides a dumping area for 2 million tonnes of rubble and soil. The greatest advantage of this is that we can cost-effectively combine the dumping of rubble with a return supply of sand in a load for load transportation.

 

In addition to the natural materials of the site at this location we also provide recycling materials such as topsoil, filling soil and gravel.

FOR EACH LOT WE HAVE GOT THE RIGHT TECHNOLOGY

Our modern machinery for your civil engineering project

Earthworks

Whether it is a detached house or a large construction site – for every scenario we have the perfect excavators, tracked loaders and rollers in various sizes.

Disposal of earth

Over a hundred containers and a fleet of advanced dumper trucks guarantee a rapid, safe and flexible transportation of excavated earth from your construction site.

Recycling

In our own, centrally situated recycling plant we treat mineral construction waste, soil, sand, mixed construction waste as well as contaminated soils.
