Challenges & Applications

ENSURING EFFICIENT TUNNELLING THROUGH PROPER SOIL CONDITIONING

The efficient use of EPB shields for tunnelling offers even-pressure support of the work face.  Soil conditioning has to be carried out in order to meet the requirements placed on the excavated soils serving as the support medium.

With MC-Montan Drive, MC offers conditioning agents specifically adapted to varying geological conditions, enabling you to achieve high tunnelling advance rates with a good degree of efficiency, reliability and environmental compatibility.  

ANNULAR GAP GROUTING SYSTEMS FOR RELIABLY BEDDED TUNNEL PROFILES

The annular gap that results during tunnel driving between the shield and the in-situ material is backfilled with grouting mortar to minimise surface subsidence and stabilise loose rock.

Injected into the annular space over the full area, the mortar is formulated for stiffness and strength values aligned to those of the surrounding rock material. MC has a number of one-component and two-component annular gap grout formulations within its MC-Montan Grout range that can be aligned to the in-situ rock conditions specific to your tunnel construction project. This means that every tunnel profile is provided with the optimum bedding solution for minimum subsidence. 

Enhance safety, efficiency, and performance in your mining operations

Operating in unstable and unpredictable geological conditions requires innovative, reliable solutions to ensure smooth operations and workforce safety. We deliver advanced products for consolidation and stabilization, including shotcrete, rock and cable bolting materials, specialized resins, and backfill solutions.

Our technologies improve efficiency, protect workers, and minimize environmental impact. Engineered for your site-specific needs, our admixtures – such as shotcrete accelerators, water reducers, and hydration control agents – optimize performance under challenging conditions. Shotcrete accelerators enable rapid ground stabilization, ensuring safer mining progress, while water reducers deliver high-strength, workable concrete without compromising structural integrity. Hydration control agents ensure extended workability, accommodating long transport times. Rely on us to address your mining challenges. Go to the microsite
