Introduction

HB Tunnelling is delighted to announce a significant multi-million pound investment with the acquisition and deployment of two new state-of-the-art Microtunnelling Boring Machines (MTBMs).

This strategic expansion ensures our fleet remains at the forefront of trenchless technology, substantially increasing our capacity and technical capability for complex, high-accuracy pipeline installations across the UK.

Our newest AVN series Microtunnelling Boring Machine, ready for deployment on critical infrastructure projects.

Enhanced Capacity and Precision

The new MTBMs integrate the latest advancements in guidance and remote control technology. This investment directly addresses the increasing demand for trenchless solutions in constrained and sensitive environments (such as rail and urban crossings).

Key Client Benefits of the New Fleet:

  • Increased Speed: The enhanced power and cutting efficiency of the new rigs reduce project timelines, delivering faster completion for time-critical schemes.
  • Greater Accuracy: Advanced laser guidance and real-time steering systems guarantee millimeter-level precision, essential for gravity sewers and demanding alignment tolerances.
  • Wider Scope: The new rigs allow us to handle a broader range of diameters and geotechnical conditions, from dense clay and rock to challenging mixed-face environments.
  • Reduced Risk: Remote, non-man-entry operation ensures the highest safety standards (ISO 45001) are maintained, particularly when working below the water table.

Fueling Design & ECI Excellence

This technological investment is fully synchronized with our Design & Engineering division. Our ECI team and certified CREs can now confidently propose solutions for previously unviable schemes, leveraging the superior power and capability of the new fleet to overcome site-specific challenges.

We view our plant investment as an extension of our commitment to quality. Maintaining a modern, reliable fleet minimizes downtime and maximizes efficiency, translating directly into project certainty for our clients.

This isn't just a fleet upgrade; it's a commitment to future-proofing our service. These rigs unlock new levels of efficiency and assurance, allowing us to tender confidently for the most complex underground projects in the UK infrastructure sector."
Hugh Boyle - Chairman

Conclusion

The deployment of these next-generation MTBMs marks a significant milestone in HB Tunnelling’s expansion. As we continue to invest in our technology and our people, we are excited to apply this enhanced capability to your next critical infrastructure project.
