BAUER MAT Slurry Handling Systems

With groundbreaking machines and innovative solutions for special foundation engineering, the BAUER Maschinen Group, Schrobenhausen/Germany, once again set new industry standards at bauma 2025. Several thousand industry professionals flocked to BAUER City to experience the company’s latest developments and technologies up close. The broad range of exhibits included BAUER’s proven rotary drilling rigs, diaphragm wall technology and drilling tools, as well as innovative products from its subsidiaries KLEMM, RTG, and BAUER MAT. Eurodrill was also present, as in previous years, with its own booth showcasing drilling drives.

A key highlight was the new BCS 185 power pack cutter system (Figure 1). Featuring a modular drive concept, it offers flexible operation with either electric or diesel power. This system allows for locally emission-free use and variable positioning of the power unit to reduce the footprint on construction sites.

Another standout exhibit was the eRG 21 t hybrid from RTG Rammtechnik. The combination of a powerful 430 kW diesel engine with an additional 88 kW electric motor enables operation with up to 68 % fewer CO₂ emissions – a clear reflection of BAUER’s commitment to sustainable innovation.

KLEMM Bohrtechnik impressed with the newly developed KR 806-4E, an evolution of its electrohydraulic KR 806-3E drilling rig. The latest version offers increased motor power, improved battery capacity and an optimized electric system – delivering environmental performance without compromising the power of its diesel-hydraulic counterparts.

BAUER MAT Slurry Handling Systems presented the new CMS 50 colloidal mixer, which boasts a 10 % larger mixing volume than its predecessor, along with cutting-edge technology and a new design. In the field of injection technology, MAT unveiled the fully automatic IPA 250-E. It combines proven MAT mixing technology with Obermann pump technology, setting new benchmarks in injection processes.

A particularly noteworthy innovation showcased at the BAUER booth was the prototype of the electronic Cutter Soil Mixing (eCSM) system. As the world’s first electrified diaphragm wall method, it replaces traditional hydraulic components with a powerful electric drive architecture – reinforcing BAUER’s position as a technological leader in this field.

Peter Hingott, Member of the Executive Board of BAUER, emphasized: “We want to place even greater focus on our innovative strength and engineering expertise. BAUER is already a leader in the industry, but our goal is to be the best. We don’t just deliver products – we offer complete solutions for our customers’ challenges.”

Wulf Flos, Managing Director of BAUER Maschinen GmbH, added: “Our products are designed to inspire customers around the globe. As a premium manufacturer, we rely on strategic partnerships and outstanding service. Once again, bauma 2025 proved that we are shaping the industry with state-of-the-art technology, sustainable solutions, and low emission drive systems. The feedback on our BAUER City and the exhibits was excellent. A strong order intake speaks for itself.”

In North Yorkshire, one of the UK’s deepest underground mines is being constructed by Sirius Minerals Plc over the next five years. The mine will extract polyhalite, a high-quality organic fertiliser consisting of the minerals calcium, magnesium, sulphur and potassium. The project is unique because all mining and transportation operations will take place completely underground, once the Woodsmith Mine is completed. This means that polyhalite can be extracted with minimal impact on the region’s tourism and the North York Moors National Park.

As part of the 2.5 bn € project, BAUER Technologies Ltd., a subsidiary of BAUER Spezialtiefbau GmbH, Schrobenhausen/Germany, has been contracted to build circular diaphragm wall shafts between 60 and 120 m deep (Figure 1). Construction of the diaphragm wall for the service shaft began in December 2017. Among other equipment, three BAUER BC 40 cutters on MC 96 and MC 128 duty-cycle cranes (Figure 2), and three complex BE 500 and BE 550 desanding plants from BAUER MAT Slurry Handling Systems are being used in the project. The bentonite suspension is enriched with a specially developed polymer-based additive to minimize losses into the fractured and porous strata.

Different measurement methods are being combined to produce a clear 3D model of the diaphragm walling works using Building Information Modeling (BIM). This will ensure that the required maximum vertical deviation of 200 mm in 120 m is not exceeded. Once Bauer Technologies has completed the diaphragm shafts, in a follow on operation the production and service shafts will be sunk to a final depth of 1,500 m by a mining company.

Bauer Technologies has made a name for itself in the UK, thanks to the success several extremely complex and technically challenging projects has been involved in. These include specialist foundation engineering works for the redevelopment of the Battersea Power Station in London and work for the important Crossrail infrastructure project.

MAT Mischanlagentechnik GmbH, Immenstadt/Germany, has been delivering state-of-the-art mixing and separation technology for over 25 years. Since 1st April 2018 the branch office of BAUER Maschinen GmbH, Schrobenhausen/Germany, has been operating under the new name BAUER MAT Slurry Handling Systems, underscoring its affiliation with the international BAUER Group.

“We are now merging even more closely with the Group, and this will also be reflected in our name. We are repositioning ourselves, and we’re doing it together with Bauer,” says Alexander Konz, branch manager at MAT. With the new name, the company will take the next step in its future strategy. This will include strong growth in the international markets as well as significant expansion of the company’s tunneling business.

In addition, BAUER MAT Slurry Handling Systems plans to further expand its core business of developing and manufacturing state-of-the-art mixing and separation equipment for challenging specialist foundation engineering and tunneling projects (Figure 1). By doing this and expanding the sales and service network, the company will be in an even better position to tap the full potential of local markets in the future, says Konz. “As a global player, Bauer has production and sales locations in numerous countries around the world. I’m confident that both our customers and employees will benefit further from our increased cooperation,” he says.
