What We Do
We specialize in transforming raw site data into actionable insights. Our site investigations are designed to:
Inform Project Design
Provide data that guides safe, cost-effective, and sustainable engineering solutions.
Evaluate Geotechnical Properties
Analyze soil, rock, and groundwater conditions to determine load-bearing capacity and stability.
Assess Geological Conditions
Understand the natural composition and behavior of your site.
Each investigation is tailored to your project’s unique requirements, ensuring optimal outcomes and reduced risks.
Our Key Services
Borehole Drilling
Our borehole drilling services are essential for collecting subsurface samples and data:
- Deep & Shallow Drilling: We perform both deep and shallow boreholes to capture a comprehensive profile of the subsurface.
- Sample Collection & Analysis: Extract and analyze soil, rock, and groundwater samples to assess site stability and composition.
- Customized Drilling Programs: Tailored drilling strategies based on project size, location, and specific investigative needs.
Geophysical Surveys
Using non-invasive techniques, our geophysical surveys provide a detailed picture of subsurface conditions:
- Seismic Refraction & Reflection: Determine subsurface layering, depth to bedrock, and potential anomalies.
- Electrical Resistivity: Map variations in soil and rock properties to detect moisture content and material differences.
- Ground Penetrating Radar (GPR): Identify subsurface features, voids, and other potential issues without disturbing the site.
In-Site Testing
Our in-situ testing methods evaluate the real-world performance of subsurface materials:
- Standard Penetration Tests (SPT): Measure soil resistance to determine density and strength characteristics.
- Cone Penetration Testing (CPT): Provide continuous profiles of soil properties to inform foundation design.
- Pressuremeter Testing: Assess soil deformation and strength under load, ensuring safe foundation parameters.

FAQs
Have questions? We have answers:
What types of projects benefit from site investigations?
Our site investigations are critical for any construction or development project, including residential, commercial, industrial, and infrastructure projects.
How do geophysical surveys complement borehole drilling?
Geophysical surveys provide a non-invasive overview of the subsurface, while borehole drilling allows for detailed, localized analysis. Together, they offer a comprehensive understanding of site conditions.
How long does a typical site investigation take?
The duration depends on project size and complexity, but we work closely with clients to establish timelines that align with project needs and milestones

Frequently asked questions
What is the difference between a site investigation and a geotechnical report?
The site investigation is the field and laboratory work: the desktop study, the boreholes, test pits, hand augers, Scala penetrometer or CPT probes, groundwater observations and any laboratory testing. The geotechnical report is the engineering document produced from that data, which interprets the ground model and gives design parameters, bearing capacities, settlement estimates and recommendations. A consent application needs the report, but the report is only as good as the investigation behind it.
How deep does a site investigation need to go?
Deep enough to cover the zone of influence of the proposed structure and to prove the founding material. For a single dwelling on shallow foundations that is often 3 to 5 metres, or to refusal. For piled foundations, multi-level buildings or retaining structures the investigation must extend below the pile toe or the failure surface being assessed, which can be 10 to 20 metres or more. On sloping sites the depth is driven by the depth of any potential slip surface rather than by the building alone.
How long does a site investigation take?
Field work on a typical residential site is usually one day. Allowing for utility location, machine access and booking, a reasonable expectation from instruction to reporting is two to three weeks. Where laboratory testing is required, where the site needs specialist access, or where council has asked for a specific scope, this can extend. Sites with restricted access or requiring traffic management should be programmed with more contingency.
