Hunter Geotechnical Services ensures the integrity of your earthworks projects through comprehensive testing and monitoring services. From initial planning to completion, we conduct stability, drainage, and pavement tests, ensuring that your construction project complies with all relevant specifications. Our earthworks testing services provide reliable data for both minor and major projects, supporting everything from slope stability assessments to density testing and pavement design. With our expert team and NATA Accredited laboratory, you can confidently move forward with your project, knowing the foundations are solid.
Our focus at Hunter Geotechnical Services is to deliver efficient and reliable earthworks testing services that meet the highest industry standards. Whether your project involves stabilised pavements, drainage systems, or unbound and asphalt pavements, we provide testing solutions that ensure compliance and quality. Our team of engineers and technicians is highly experienced in conducting both field and laboratory testing, offering clients a complete package of testing services for any type of earthworks project.
Key Earthworks Testing Services
Compliance Testing for Minor and Major Projects
We perform earthworks testing to ensure compliance with Transport for NSW (TfNSW) and Australian Standards (AS) specifications. Our services cover everything from planning and stability testing to surface drainage and pavement conformance, ensuring your project meets regulatory requirements at all stages.
Site Inspections and Monitoring
We offer site inspections, including proof-rolling, excavation monitoring, and density testing, to verify compliance and identify any potential issues during the construction process. Our field tests are designed to provide immediate feedback to ensure that the project remains on track.
Field and Laboratory Density Testing
Our team conducts both field and laboratory density tests to ensure the material used in your earthworks project meets the required specifications for compaction and stability. This includes testing soil characteristics such as the Plasticity Index, Shrink/Swell, Particle Size Distribution, and Emerson Class, providing detailed insights into the suitability of the materials.
Engineered Fill Verification and Certification
We provide Level One Earthworks Supervision and certification according to AS 3798, ensuring engineered fill is suitable for rail formation or bulk earthworks. Our services include verifying fill materials and issuing certifications that demonstrate compliance with Australian standards.
California Bearing Ratio (CBR) Testing
CBR testing is essential for determining the strength of subgrades and pavements. Our team conducts CBR tests to support the design of roads, highways, and other infrastructure, ensuring your project has the necessary structural integrity.
Pavement Testing and Supervision
We offer roadwork testing, supervision, and assessment services, including Benkleman beam testing to measure pavement deflection, as well as Dynamic Cone Penetrometer (DCP) testing to assess ground consolidation and bearing capacity. These tests are critical for ensuring that your pavements are designed and constructed to withstand long-term use.

Frequently Asked Questions
1. What is Level One Earthworks Supervision?
Level One Supervision, as defined by AS 3798, involves a certified supervisor being present on-site to monitor earthworks and ensure compliance with engineering designs and specifications. This supervision is critical for large projects involving engineered fill or bulk earthworks.
2. Why is CBR testing important?
CBR testing measures the strength of subgrade soils and their suitability for supporting roads, pavements, and other infrastructure. It helps engineers determine the necessary pavement thickness and design for long-term performance.
3. What are some key field tests you perform during earthworks projects?
We conduct a variety of field tests, including proof-rolling, Benkleman beam testing for pavement deflection, and Dynamic Cone Penetrometer (DCP) testing for ground consolidation. These tests ensure that the materials and design are suitable for the project’s needs.

Specialist Capability
Plate Load Test
Hunter Civilab’s Plate Load Test can quickly and easily determine the bearing capacity of soils and deflection of soils.
The test is performed by systematically applying 6-8 equal load steps to the static plate, and calculating the pressure settling lines and deflection modules of the first load (Ev1), and the second load (Ev2) – ultimately represented in NM/m2.
The test is performed in-situ, gives instant results, and has the added benefit of being non-destructive – with no drilling or sampling. Our Plate Load Tests are performed in accordance with DIN 18134:2012-04.
