Innovations

The BAUER Group is associated with the most difficult and largest foundation tasks around the world, which are executed with powerful, innovative and highly efficient equipment. We have also made a name for ourselves in environmental services. Our companies successfully manage projects for water and natural resources worldwide. Our skills and know-how form the foundation for our success and the trust our customers place in us.

It’s the people who drive innovation in the BAUER Group. Teams pull together and achieve the impossible. The drive to continually improve and develop is a firmly anchored component of our company culture. We continually expand limits.

Soil as construction material

Why remove drill spoil and bring in concrete if the existing soil can be used as construction material? With innovative soil mixing techniques, Bauer improves construction soil efficiently and sustainably, right on-site. The specialist foundation engineering experts create load-bearing soil mixing elements which can be used, for example, as a foundation for structures, as walls for excavation pits or to seal off dams. Bauer continuously improves its mixing technology in order to create custom cement slurries and mortars that are precisely tailored to the local geological conditions. Environmental benefits are resource efficiency and the reduction of CO2 emissions. Since the soil does not have to be removed and disposed, and the slurry is produced on site, long transport routes are eliminated. In addition, less bentonite is consumed during soil mixing, which reduces CO2 emissions even further.

Performance quadrupled

With its quadruple mixing drive, the Multi Shaft Mixing System (MSM) of RTG Rammtechnik GmbH system offers a level of flexibility and efficiency that far exceeds conventional triple mixing drives. Particularly for soil mixing, the MSM system has proven to be an economical and versatile solution. The centerpiece of the MSM system is up to four independent rotary drives that insert the mixing paddles – aligned parallel to one another – into the soil. Binding agent is continuously pumped in through the hollow stems. Thanks to the multiple rotary drives, various mixing distances and configurations can be adapted to the individual site requirements. The MSM system It is used when constructing cut-off walls in contaminated soils, for groundwater barriers and for the sealing and rehabilitation of dams and dikes. The system also proves its strengths in excavation pits and when it comes to soil improvement.

Soil mixing goes electric

The vision of the BAUER Cutter Mixing (eBCM) research project is to develop a new electrical mixing tool that improves efficiency and environmental compatibility. Specifically, this means relying on an electrical motor directly in the gearbox instead of the diesel-powered hydraulic drive. This saves space and significantly increases the mixing speed. During load tests at the company’s plant, Bauer Maschinen has already successfully used the electric motor for soil mixing under real conditions with cement slurry. The long-term objective is to convert the entire cutter and CSM process with Bauer equipment to the use of power from renewable energy sources.

Energy from the earth

As a future-proof and environmentally friendly key technology, geothermal energy is the solution for a sustainable heating transition. It harnesses the earth's heat to warm buildings in winter and cool them in summer. BAUER Resources GmbH has been driving this technology forward for years to help create a greener future. the motto “All from a single source” is more than just words – it’s a guiding principle. The company supports geothermal projects from initial consultation to completion and beyond. Even the equipment and materials used in geothermal projects come from a single source: KLEMM Bohrtechnik GmbH, a member of the BAUER Group, supplies high-performance drilling equipment, while the subsidiary GWE GmbH provides high-quality well construction materials. This integrated approach enhances efficiency and guarantees the highest standards of quality.

Less PFAS, more future

PFAS – per- and polyfluorinated alkyl substances – can be found in numerous everyday products from cosmetics to clothing, packaging and coatings all the way to fire extinguishing foams. Their ability to repel water, grease and dirt was long considered an advantage. However, the widespread use of PFAS has serious consequences: These so-called "forever chemicals" severely contaminate the soil and are extremely difficult to remove. The Bauer Umwelt Division of BAUER Resources GmbH has developed a ground-breaking solution: a mobile soil purification plant that efficiently tackles PFAS pollution. Whether on military sites, industrial brownfields or agricultural areas.
