Focus on tunnelling and mining

The MCU business unit evolved from the former Tunnelling business unit and focuses on the specific needs of mechanical tunnelling (TBM), conventional tunnelling and mining. A team of experienced international specialists supports customers throughout the entire value chain, providing assistance with product selection, ensuring reliable supply chains, offering technical advice and, above all, hands-on support on construction sites. MCU sees itself as a full-service partner for underground projects worldwide, consistently pursuing a solution-oriented approach.

High-performance technologies for demanding applications

MCU's motto is 'Advanced Underground Solutions – Reliable, Efficient and Built for the Toughest Conditions'. The business unit offers technologies that ensure safety, efficiency and durability even in extreme conditions. It focuses on high-quality products and technologies 'Made in Germany' that meet the strictest quality and performance requirements.

MCU also focuses on providing simple, fast and safe solutions, specifically tailored to the conditions of each tunnelling and mining project. Rather than selling individual products, the business unit follows a holistic systems approach, focusing on integrated solutions for specific customer requirements. This performance promise is complemented by comprehensive global technical services delivered by experienced and certified experts.

Ultimately, the key benefit for MCU’s customers lies in the combination of experience, flexibility, efficient on-site support and, above all, technological competence that is reflected in innovative and unique underground solutions such as soil conditioning with StartupFoam™ or SolidFoam™, or the production of annular grouts with the MC-Montan Grout series, which are used successfully in tunnel construction projects worldwide.
