Competencies

Whether innovative residential construction projects, complex neighborhood developments or modern infrastructure concepts – we offer individually tailored and optimized solutions for all of your projects. We construct turnkey excavation pits according to the geological, local and engineering conditions, relying on established methods, state-of-the-art technology and decades of experience. Depending on the requirements, we execute soldier pile walls, our patented Mixed-in-Place method or sheet pile walls, bored pile walls, diaphragm walls or cut-off walls. We offer complete solutions from a single source: Going deep, since our excavation pits get the job done reliably at great depths. We ensure the ideal framework conditions for your project. 

Record-breaking skyscrapers with residential, office and business spaces, imposing bridges or extensive industrial and commercial buildings: All these buildings require a solid basis to discharge the generated loads safely and reliably into the stable construction soil. With proven pile foundations up to depths of far more than 100 m and diameters of more than 2 m, we offer perfect results for your project as well. Diaphragm wall panels, Mixed-in-Place elements or the use of injections are other effective and economical options for discharging structural loads. We offer the optimal foundation type for every structure in building construction, bridge or transport route construction with state-of-the-art technology and create the optimal basis for your one-of-a-kind construction project – individually tailor-made to the existing conditions.

Challenging soil conditions and difficult construction soil with a low load-bearing capacity? That’s no problem for us! We make it possible to use these sites for construction through soil improvement, helping your individual project become a reality. As a result of increasing urbanization, particularly in metropolitan areas, more and more buildings are being constructed in areas with difficult, weak load-bearing subsoils. By using suitable methods, we make it possible to implement demanding construction projects. From Vibro Compaction and Vibro Replacement to Vibro Concrete Columns as well as Dry Vibro Concrete Columns DVCC all the way to Dynamic Compaction: We offer efficient solutions to minimize settlements, to discharge structural loads broadly into load-bearing soil strata and to guarantee the stability and safety of slopes. We also use our patented Mixed-in-Place method or injections to considerably increase the load-bearing capacity of the soil. 

The elemental force of water continually endangers residents and buildings near still and flowing bodies of water or close to groundwater level. Whether for sealing off reservoirs, dams and dikes or for the encompassment of landfills, tank farms and industrial sites: We offer you permanent, well-established and economical system solutions for your project with drilled, excavated or milled cut-off walls. In addition, our project-specific retaining structures comprising diaphragm walls, pile walls and sheet pile walls make it possible to carry out construction in groundwater. The required horizontal seals in the form of grouting of underwater concrete slabs as well as soil improvements near existing buildings are added as needed. In this way, our proven cut-off walls ensure stability and act as a vertical seal to protect individual buildings, entire areas or the local environment against the force of water.
