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.

Advanced Technologies for Precise Results

Using the most advanced technologies, GEOCIVIL delivers accurate and high-quality results that give you a clear understanding of the ground composition beneath your site. Our geophysical testing services provide valuable data to reduce risk and prevent costly issues before construction begins, ensuring your project is built on a solid foundation.

Our Geophysical Testing Services Include:

Ground Penetrating Radar (GPR)

GPR is a non-invasive technique that uses radar pulses to image the subsurface. It’s highly effective for detecting objects, voids, changes in material, and other anomalies beneath the surface. Whether you need to locate utilities or assess ground conditions, GPR provides real-time, reliable data without the need for extensive digging or disruption.

  • Detects buried utilities, pipes, and cables.
  • Maps changes in subsurface materials and conditions.
  • Identifies voids or other underground features that may impact project planning.

Nuclear Densometer (NDM)

The Nuclear Densometer measures soil density and moisture content quickly and accurately. This testing method is widely used for compaction control in roadworks, embankments, and other construction projects where precise soil density data is essential for ensuring the stability and performance of the foundation.

  • Determines soil density to assess compaction quality.
  • Measures moisture content for optimal material performance.
  • Ideal for road construction, foundations, and embankments.
