The Method
Remotely Steered Precision, Bore After Bore
Micro-tunnelling advances a shielded, laser-guided machine from a launch shaft to a reception shaft, jacking pipe behind it as it goes. Operators steer from a surface control cabin, holding line and grade to within millimetres — even through saturated ground or beneath live infrastructure.
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.
