Service Overview

Microtunnelling is the method of choice for pipejacking – and it’s easy to see why. It’s non-invasive, thanks to remote-controlled, laser guided systems.

Installation of service pipelines, where other, invasive methods are not suitable, are ready-made for microtunnelling.

This sophisticated system is used primarily when a tunnel is needed to cross under obstacles such as dense traffic roads, railways and rivers. This trenchless solution has plenty of benefits, including:

  • Pinpoint accuracy
  • Enhanced site safety
  • Reduction of surface disruption
  • Reduced environmental impact

It’s why we specialise in microtunnelling services. Our experienced team and cutting-edge fleet mean there is no project we can’t complete. All types of ground conditions are catered for, so we can provide you with the high-quality, watertight finish you expect when you work with us.
