Horizontal Directional Drilling in Auckland
Professional HDD and trenchless underground utility installation throughout Auckland and the North Island.
What is Horizontal Directional Drilling?
Horizontal directional drilling (HDD) is a trenchless method of installing underground pipes, ducts and services without excavating a continuous open trench.
Using specialist directional drilling equipment, a controlled pilot bore is drilled along a planned underground route. The bore can then be enlarged before the required pipe or duct is pulled into position.
HDD is particularly useful where underground services need to cross roads, driveways, landscaped areas or other existing infrastructure while reducing surface excavation and reinstatement.
Ultimate Drilling provides horizontal directional drilling throughout Auckland and the North Island for civil, utility and infrastructure projects.
Why Use HDD?
✓ Less surface excavation
✓ Reduced disruption to roads and driveways
✓ Less reinstatement required
✓ Suitable for many utility installations
✓ Useful around existing infrastructure

How Horizontal Directional Drilling Works
Horizontal directional drilling uses a controlled, steerable drilling process to install underground pipes and ducts along a planned bore path. The process allows services to be installed beneath roads, driveways and other existing infrastructure while minimising surface excavation.
01 – Site & Service Planning
The proposed bore route is assessed, existing services are identified and the installation path is planned around site conditions and project requirements.
02 – Pilot Bore
A steerable pilot bore is drilled along the planned underground route while the drill head is tracked to maintain the required direction and depth.
03 – Reaming
Where required, the pilot bore is enlarged using a reamer to create a suitable bore diameter for the pipe or duct being installed.
04 – Pipe or Duct Installation
The required pipe or duct is pulled through the prepared bore, completing the underground installation with minimal surface excavation.

Is Horizontal Directional Drilling Suitable for Your Project?
Every HDD installation is different. We assess the project requirements before determining the most suitable drilling approach.
Horizontal directional drilling can be an effective trenchless solution for many underground utility installations, but every project needs to be assessed individually.
Factors such as ground conditions, bore length, pipe or duct diameter, installation depth, existing underground services, site access and the required bore alignment all influence the drilling approach.
For drainage and gravity sewer installations, the required grade and levels also need careful consideration. Ultimate Drilling can review the project requirements and help determine whether HDD is a suitable installation method.
Ground & Site Conditions
Ground conditions, available working space and the proposed bore route are considered when planning a directional drilling installation.
Bore Requirements
Bore length, installation depth, pipe or duct diameter and required alignment help determine the equipment and drilling approach for the project.
Existing Services & Access
Existing underground utilities, entry and exit locations, site access and surrounding infrastructure are considered when planning the bore path.
Horizontal Directional Drilling FAQs
Common questions about HDD and trenchless underground installations.
What is horizontal directional drilling?
Horizontal directional drilling (HDD) is a trenchless method used to install underground pipes, ducts and services along a controlled bore path without excavating a continuous open trench.
What services can be installed using HDD?
HDD can be used for suitable fibre and telecommunications ducts, water pipes, sewer and wastewater infrastructure, stormwater and drainage, electrical ducts, gas infrastructure and other underground utility installations.
Can you directional drill underneath roads and driveways?
Yes. Road and driveway crossings are common applications for HDD. The proposed bore still needs to be assessed for ground conditions, depth, existing underground services, access and other project requirements.
Is HDD suitable for every underground installation?
No. Suitability depends on factors including ground conditions, bore length, pipe or duct diameter, required depth, alignment, existing services and site access. Gravity drainage and sewer projects also require careful consideration of grade and levels.
Do you provide HDD outside Auckland?
Yes. Ultimate Drilling provides horizontal directional drilling throughout Auckland and can work on suitable projects across the wider North Island.
How do I get a quote for directional drilling?
Send us the available project information, including the proposed location, bore length, pipe or duct requirements, plans and any known site conditions. We can review the project requirements and discuss the appropriate HDD approach.
