AREAS OF EXPERTISE
We specialise in underground construction, with three core areas of expertise:
Specialised system solutions supporting the entire TBM operation, from soil conditioning, greases and sealing, annular gap backfilling, and segment production to injection.
Solutions for shotcrete, rock bolting, ground stabilisation, water control, waterproofing and structural protection, meeting the demanding requirements of tunnelling under complex geological conditions.
Integrated chemical and technical system solutions for ground stabilisation, injection, water control, rock bolting and void filling, supporting safety, efficiency and operational reliability in underground mining.
By combining advanced construction chemical technologies with international technical expertise, we support customers throughout the entire project lifecycle – from technical consultancy, solution development and technological innovation to the supply of high-quality products and hands-on technical support on construction sites.
AREAS OF APPLICATION
We provide solutions tailored to the specific conditions of each project, helping to improve construction efficiency, operational reliability and the long-term durability of structures. Our solutions are widely applicable, supporting both new construction as well as the maintenance and repair of existing structures.
Key areas of application include:
Solutions for TBM tunnelling in urban areas and associated underground structures.
Solutions for tunnelling, ground stabilisation, waterproofing and structural protection.
Solutions for ground stabilisation, rock bolting, water control and improved construction efficiency.
Support for construction under complex urban and geological conditions.
Solutions for water control, injection, repair and structural protection.
System solutions tailored to the specific requirements of each project.
MECHANIZED TUNNELLING (TBM)
• Soil conditioning: Foam, polymers and specialised soil conditioning technologies for TBM applications.
• Greases & Tail sealants: Main bearing sealing grease, main bearing grease, tail sealants for initial filling and shield tail sealing systems.
• Annulus grouts Superplasticisers, activators and specialised grout systems.
• Precast tunnel lining components & segments: Concrete admixtures, release and curing agents, reinforcing fibres, concrete repair & cosmetics.
• Injection solutions: Solutions for joint sealing and water control, structural filling and strengthening, ground stabilisation and void filling, waterstop and waterproofing systems.
CONVENTIONAL TUNNELLING / NATM & MINING
• Shotcrete Systems: Accelerators, PCE-based superplasticisers, hydration control admixtures, rebound control agents and structural reinforcing fibres.
• Rock bolting & Ground anchoring: Non-shrink grouts, grout performance-enhancing admixtures and fast-curing PUS resins for anchoring applications.
• Ground injection & Water control: PU/PUS resins, acrylate gels and rigid foaming resin systems for ground stabilisation, sealing and water control.
• Waterproofing & Surface protection: Spray-applied or PVC waterproofing membranes, structural repair and reprofiling mortars, and protective coating systems.
• Cemented backfilling: Rheology-modifying plasticising admixtures to optimise binder consumption and improve the efficient utilisation of mining waste in underground mine backfilling.
• On-Site engineering & Technical support: Custom formulation development and adjustments tailored to project needs, on-site training (including EFNARC-supported training and certification), equipment calibration and early-age concrete quality testing.
From Solutions to Project Performance
Every solution is developed not only to meet technical requirements, but also to deliver overall project performance – optimising construction, enhancing reliability, managing risks and ensuring long-term durability.
ADVANCED GERMAN TECHNOLOGY – INTEGRATED, TAILORED SOLUTIONS
Combining advanced German technology, international experience and in-depth expertise in underground construction, we provide integrated solutions selected and adjusted to the geological conditions, construction methods and technical requirements of each project. This helps optimize construction efficiency, ensure quality and enhance reliability under challenging construction conditions.
PRECISION – MAXIMUM SAFETY – OPTIMISED PROJECT SCHEDULES
From quality control to operational performance, the solutions from MC-BIFI and MC Underground are developed to meet the most demanding requirements of underground construction projects. They improve precision, enhance safety, minimise risks and optimise construction schedules – supporting sustainable project performance throughout the entire project lifecycle.
24/7 TECHNICAL SUPPORT – EXPERTISE THROUGHOUT THE PROJECT
The MC-BIFI technical team works closely with MC Underground’s international network of experts, providing support throughout the project – from solution selection, testing and optimisation to training, implementation and on-site technical support. This continuous support ensures that solutions are applied appropriately to actual site conditions and enables technical requirements arising during construction to be addressed promptly.
