Efficient and Accurate Bore Hole Drilling with Our Hilux Mounted Drill Rig

Our Hilux mounted drill rig is revolutionising the geotechnical investigation process.

Designed for efficiency, precision and accessibility.

This innovative rig allows our GWE Engineers and Geologists to perform reliable bore hole drilling without the need for costly commercial equipment.

By significantly reducing costs and time compared to traditional methods, it is an essential tool for a variety of applications, ranging from residential to large-scale industrial developments.

Why Choose Our Hilux Mounted Drill Rig?

The Hilux mounted drill rig is tailored for flexibility, speed, and accuracy. Here’s how it outperforms traditional methods and why it is an indispensable resource for geotechnical work:

Cost-Effective Solution

Unlike commercial drilling equipment, our rig provides a cost-effective alternative without compromising on performance. It allows us to deliver results faster and at a fraction of the cost.

 

Enhanced Speed and Efficiency

By eliminating the slow-paced nature of hand auger methods, our drill rig enables us to reach depths of 2 to 8 metres much more efficiently. Geotechnical investigations no longer have to be time-consuming.

 

Access to Challenging Terrain

Our drill rig can go wherever a standard 4WD utility vehicle can travel, making it perfect for locations with difficult access. It can handle the varied landscape of central North Island with ease.

 

Precision Soil Sampling

Fast and effective soil profile logging is ensured, even in challenging conditions such as encountering gravelly sands or groundwater. With continuous flight augers of 75mm diameter, we can retrieve undisturbed samples across the soil profile for accurate analysis.

Ideal Applications of the Drill Rig

Our Hilux-mounted drill rig has proven its value in the following areas:

  • Preliminary Liquefaction Studies: Screen soil conditions to assess liquefaction potential in earthquake-prone zones.
  • Foundation Recommendations: Obtain accurate foundation data for diverse projects, including residential, commercial, rural, and industrial developments.
  • Stormwater Management: Drill and test infiltration rates to inform stormwater soakage solutions.
  • Groundwater Wells: Install temporary, PVC-screened wells to assess water table conditions.

Its versatility has supported thousands of successful investigations over the past 20 years across the central North Island.

Technical Capabilities at a Glance

To truly appreciate the advantages of this drill rig, consider its technical capabilities:

  • Depth Range: Standard bore holes reach between 4 to 6 metres, providing ample depth for most geotechnical applications.
  • Testing Flexibility: Drill holes allow for Dynamic Cone Penetrometer (DCP) testing at 1-metre intervals, or shear vane testing at 0.5-metre intervals—ensuring data is collected precisely where it is needed.
  • Groundwater Monitoring: We drill temporary groundwater monitoring wells lined with durable PVC screens for accurate water level assessments.
  • Stormwater and Foundation Analysis: Perfect for stormwater soakage tests and foundation design—including residential, rural, commercial, and industrial developments.

A Consistent Quality Assurance Process

Our commitment to quality assurance sets us apart. Every bore hole we drill is sampled, with soil profiles transported back to our state-of-the-art laboratory for review by senior geotechnical staff. By adhering strictly to the NZGS (New Zealand Geotechnical Society) Field Description of Soil and Rock standards, we ensure our data accuracy and provide our clients with unmatched confidence in reporting and recommendations.

Proven Performance Over Two Decades

With over 20 years of extensive use across central New Zealand, our drill rig has consistently delivered reliable outcomes for thousands of geotechnical investigations. Whether it’s foundation recommendations for rural homes or soakage tests for commercial developments, the results speak for themselves. This tool is trusted by geotechnical engineers, geologists, land developers, homeowners, and construction companies alike.
