Our Process
Remotely steered precision, bore after bore
Micro-tunnelling launches a micro tunnel boring machine from a shaft and controls it entirely from the surface. From a computer control cabin, a single operator steers with real-time line and grade monitoring, while slurry pressure balances groundwater and earth pressure — preventing settlement even in unstable soils.
Our Process
How It Works
A disciplined four-stage delivery, every time.
01
Survey & assessment
Geotechnical investigation and utility mapping to de-risk the crossing before design begins.
02
Engineering & method statement
A crossing-specific design and a reviewed method statement, signed off before mobilisation.
03
Execution & monitoring
Real-time steering and progress tracking, with daily reporting back to the client.
04
Handover & as-built
Full as-built survey and documentation package delivered at completion.
