Horizontal Directional Drilling (HDD)

We offer professional horizontal directional drilling (HDD) services for water installations, providing a trenchless solution that minimizes surface disruption. Our process allows water mains to be installed accurately beneath roads, waterways, and existing infrastructure using advanced drilling equipment and proven techniques. This efficient and environmentally friendly method ensures precise alignment, reduced restoration costs, and reliable, long-lasting water infrastructure.

Why Choose Us?

Site Assessment and Drill Setup

Before drilling begins, we carry out a thorough site assessment based on the contractor’s approved design. This includes confirming entry and exit points, verifying existing services, assessing ground conditions, and setting up equipment to suit the specified bore profile. Proper preparation and setup ensure the drilling operation is carried out safely, efficiently, and in full accordance with the project design.

Pilot Hole Drilling with Guided Accuracy

The drilling process starts with a pilot hole, drilled along the planned alignment using advanced guidance systems. This allows us to control depth and direction with high accuracy, even beneath roads, rivers, and sensitive infrastructure. Continuous monitoring ensures the bore stays on course and meets all design specifications.

Bore Enlargement and Ground Stabilisation

Once the pilot hole is complete, the bore is enlarged through a controlled reaming process to suit the diameter of the water pipeline. Drilling fluid is used to stabilise the bore, remove spoil, and reduce ground movement. This step ensures a clean, stable pathway for the pipe while protecting surrounding ground conditions.

Water Main Installation and Pullback

After reaming, the water pipeline is securely attached and carefully pulled through the bore. This pullback process is carried out under controlled conditions to prevent stress or damage to the pipe. Our experienced operators ensure the pipeline is installed smoothly, accurately, and in full compliance with industry standards.

Drilling Fluid Management and Recycling

Effective management of drilling fluid is a critical part of the horizontal directional drilling process. We control, collect, and recycle drilling mud and water throughout the operation to maintain bore stability and reduce environmental impact. Using dedicated recycling systems, we separate spoil from fluid for reuse, helping to keep the site clean, compliant, and efficient while minimising waste and disposal requirements.

Testing, Quality Assurance, and Site Restoration

Following installation, the pipeline is tested to confirm alignment, integrity, and performance. We carry out all required checks before completing final connections. Because HDD is a trenchless method, surface disturbance is minimal, allowing us to restore the site quickly and leave the area clean, safe, and fully operational.
