  • Pavement and Aggregates Testing: Ensure the strength and durability of roads and materials with tests such as compaction, particle size distribution, Benkelman Beam deflection, and crushing resistance.
  • Cone Penetration Testing (CPT): Obtain accurate data on soil properties with push tube sampling and state-of-the-art CPT rigs for precise soil profiling and foundation design.
  • Laboratory Services: Our IANZ-accredited labs offer fast and accurate testing for a variety of needs, including Atterberg limits, compaction, and expansive soil testing.
Geotechnical Testing – Accurate Ground Assessments for Successful Projects

With years of experience and a commitment to international standards, GEOCIVIL understands that a high-quality geotechnical site investigation is crucial to ensuring accurate and cost-effective ground assessments. Whether you’re planning a small residential project or a large infrastructure development, reliable geotechnical testing is essential to the success of your design and construction process.

At GEOCIVIL, we provide IANZ-accredited data that helps reduce the risk of failure at the design phase, ensuring that your project is based on solid, dependable information. Quality testing results can also lead to significant savings in both time and resources by helping you avoid costly design and construction errors.

Geophysical Testing – Accurate Subsurface Mapping for Your Projects

New Zealand’s ground composition is unique and can vary dramatically, even across a small area. Understanding the subsurface conditions of your site is critical to ensuring the success and stability of your project. At GEOCIVIL, we provide reliable geophysical testing services to map your site’s subsurface, helping you make informed decisions for the best foundation design—whether you’re working on roads, bridges, landfills, subdivisions, or other infrastructure projects.

Pavement Testing – Ensuring New Zealand’s Roads Stand the Test of Time

New Zealand’s roads face unique challenges, from varied weather conditions to heavy traffic loads. To ensure the durability and longevity of your pavement projects, trust the testing services of an IANZ-accredited laboratory with years of experience and a deep understanding of the local construction landscape.

At GEOCIVIL, we provide a comprehensive range of pavement testing services, helping contractors and engineers ensure that roads, highways, and pavements across New Zealand are built to last. Our team delivers reliable, accurate data at every stage of your project, from initial material testing to post-construction evaluations, ensuring that your pavements meet the required standards for performance and safety.

Cone Penetration Testing (CPT) – Accurate Soil Profiling Across New Zealand

Get an accurate and detailed representation of soil conditions with Geocivil’s CPT (Cone Penetration Testing) rigs. Geocivil was the first company to introduce IANZ-accredited CPT technology in New Zealand, and we continue to lead the industry by providing high-quality, reliable data you can count on for your geotechnical projects.

Our CPT operations are among the few in New Zealand to have earned IANZ accreditation, ensuring that our data meets the highest standards of accuracy and precision. Whether you’re conducting site investigations for infrastructure, construction, or development projects, Geocivil’s modern CPT equipment and experienced team are here to support your success.

Aggregate Testing Services – Ensuring Quality from Start to Finish

At GEOCIVIL, we provide comprehensive testing services for aggregate materials, ensuring they meet the required standards at every stage of your project. Our state-of-the-art laboratories are equipped to perform the essential tests that assess the material characteristics and properties of aggregates, ensuring the quality, durability, and performance of your construction materials.

You can rely on GEOCIVIL for accurate compaction and quality control testing of aggregates, conducted in strict accordance with NZS 4407, ASTM D5874, and RTA T276 standards. Our testing services help ensure that your aggregate materials comply with industry regulations and contribute to the long-term success of your projects.

Ground Penetrating Radar (GPR) – Non-Destructive Subsurface Scanning

At GEOCIVIL, our Ground Penetrating Radar (GPR) technology offers a reliable, non-destructive method for scanning a wide range of surfaces. Whether you’re detecting voids, reinforcing concrete, or locating utilities, our GPR units provide accurate and detailed subsurface data that helps reduce risk and cost across your projects.

GPR is a highly efficient tool for sensing both metallic and non-metallic features beneath the surface, making it invaluable for void detection, utility location, and structural assessment. This simple yet powerful technique ensures that unforeseen conditions are identified early, allowing you to manage projects safely and cost-effectively.

Light Weight Deflectometer (LWD) – Efficient Compaction Control

At GEOCIVIL, our Light Weight Deflectometer (LWD) technology provides a fast, non-invasive method for evaluating soil compaction and load-bearing capacity. Whether you’re working on road construction, embankments, or other earthworks, the LWD helps you efficiently manage and control compaction quality, ensuring your project meets the necessary standards for stability and performance.

Soil Testing Services – Comprehensive Solutions for Your Project

At GEOCIVIL, we provide a full range of soil testing services to ensure accurate assessments and data for your project’s foundation and ground stability. Our IANZ-accredited laboratory delivers precise and reliable soil testing results, meeting the highest standards for geotechnical investigations across New Zealand. With over 40 years of experience, GEOCIVIL is your trusted partner for soil testing, helping you reduce risks and optimise project outcomes.

Other Testing Services – Tailored Solutions for Your Project

At GEOCIVIL, we understand that every project has unique requirements. If you need a specific test that isn’t listed among our standard services, we’re here to help. Our IANZ-accredited laboratory offers flexible testing solutions to meet your project’s exact specifications, whether you require a custom test or a specialised approach.

We pride ourselves on delivering accurate and reliable results across a wide range of geotechnical and civil engineering tests. If your project has unique testing needs, we can either adapt existing methods or create a new testing procedure to provide the data you require.

Static Plate Load Tester – Precision Testing for Soil Compaction

At GEOCIVIL, our Static Plate Load Tester technology provides a reliable and efficient way to evaluate and control the compaction quality of soil and subgrades. This innovative instrument helps you manage compaction works more effectively, saving both time and cost while improving the overall quality of your construction.

Window Sampling – Portable Site Investigation for Difficult Access Locations

For sites that are difficult to access, Window Sampling offers a portable and efficient site investigation solution, allowing us to reach areas that a traditional drill rig cannot. At GEOCIVIL, our Wellington and Christchurch offices are equipped with two Window Sampling Kits, enabling us to test deeper than hand augers, particularly in regions like Wellington Greywacke or areas with gravelly material.

Our Window Sampling Kit can reach depths of 6-8 meters, providing a versatile option for geotechnical testing in space-restricted environments.
