What We Do

Three Disciplines, One Standard of Precision

Horizontal directional drilling, micro-tunnelling, and sheet piling — the full trenchless toolkit, delivered by crews who run all three in-house.

01The Method

Horizontal Directional Drilling

Horizontal directional drilling lets us install pipe and cable crossings beneath roads, rivers, and live infrastructure without opening a single trench. A pilot bore is steered along a pre-engineered profile, enlarged in stages, and the product pipe is pulled back through — all monitored in real time from the surface.

Micro-Tunnelling

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.

03The Method

Sheet Piling

Interlocking steel sheet piles are driven into the ground to form a continuous retaining wall, holding back soil and groundwater so excavation, foundation, and marine works can proceed safely. Installed by vibro, press-in, or impact methods depending on ground conditions and vibration limits.

Why Trenchless

The Case Against Digging a Trench

The same crossing, delivered two ways — and why our clients stopped choosing the first one.

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.
