Trenchless & Thrust Boring
Advanced trenchless technologies that minimise surface disruption while ensuring accuracy and structural integrity.
What We Do
Complete Ground Engineering, One Standard of Precision
Trenchless crossings, deep foundations, earth retention, dewatering, earthworks, and ground improvement — delivered with our own engineering teams and plant.

Full Capability
Every Service We Deliver
Six service lines, from trenchless crossings to ground improvement.
Earth Retention Systems
Engineered earth support that keeps excavations stable and construction environments safe.
01HDD
Horizontal Directional Drilling
Installs pipelines, ducts and cables where open-cut excavation is not practical, permitted or cost-effective — with work confined to the entry and exit points.
25–1,200 mmPipe diameter
25–1,500 mDrill length
Steel or PEPipe material
02MT
Micro-Tunnelling
A micro tunnel boring machine launched from a shaft and steered entirely from the surface, with slurry pressure balancing groundwater and earth pressure.

Sheet Piling
Interlocking steel sheet piles driven by vibro hammer to form a continuous wall that retains both soil and water, temporary or permanent.

Why Trenchless
The Case Against Digging a Trench
The same crossing, delivered two ways — and why trenchless is so often the better one.
Open-Cut Trenching
Trenchless Method
Surface Disruption
Open-Cut Trenching
A continuous open trench along the full route.
Trenchless Method
Two compact pits — the ground between is never opened.
Traffic & Access
Open-Cut Trenching
Lane closures, diversions, and blocked frontages for weeks.
Trenchless Method
Roads, businesses, and services stay open throughout.
Reinstatement
Open-Cut Trenching
The entire trench line must be backfilled and resurfaced.
Trenchless Method
Limited to the pit areas — a fraction of the cost and time.
Obstacles
Open-Cut Trenching
Rivers, rail, and live plant force costly reroutes.
Trenchless Method
Crossed directly, at depth, without touching what's above.
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.
