Comprehensive Ground Penetrating Radar (GPR) Scanning Services in Narrabri & Regional NSW

When planning excavation, construction or other ground-disturbing work, understanding what lies beneath the surface is essential. At Powervac, our ground penetrating radar (GPR) scanning services provide civil contractors, agricultural businesses, mining operators and other clients with a non-destructive way to investigate subsurface conditions before work begins.

Based in Narrabri, we service projects across regional NSW, providing specialist GPR and underground locating services in rural, regional and remote areas. Our experienced team can integrate GPR into broader site investigation and service locating requirements to help identify potential underground obstacles, reduce risk and give your project team greater confidence before excavation.

Ground Penetrating Radar Services for Various Applications

Ground penetrating radar, commonly referred to as GPR, uses high-frequency radio waves to investigate what is beneath the ground without the need for excavation. The system records reflections from different materials and buried features, allowing our operators to build a picture of subsurface conditions.

At Powervac, we use GPR as part of a professional underground investigation service rather than simply providing equipment. Our experienced operators carry out the survey, interpret the information collected and provide practical findings to support your project.

Our GPR services can assist with:

  • Underground service investigations
  • Pre-excavation surveys
  • Subsurface investigations
  • Buried infrastructure detection
  • Concrete and structural investigations
  • Void and anomaly detection
  • Site investigation and planning
  • Supporting broader underground locating requirements

Non-Destructive Underground Investigation

One of the key advantages of GPR is that it allows areas to be investigated without immediately breaking ground. This can help identify potential buried objects and changes in subsurface conditions before excavation begins.

By gaining a clearer understanding of the area beneath the surface, project teams can make more informed decisions about where and how excavation or other ground works should take place.

Underground Service Locating With GPR

GPR can form an important part of a broader underground service locating process, particularly where buried infrastructure may not be clearly documented or visible from the surface.

Our team can investigate areas for potential underground pipes, cables, conduits and other infrastructure, helping identify locations that may require further consideration before excavation.

GPR can be particularly useful where conventional locating methods alone may not provide all the information required. We assess the site and use appropriate locating and investigation techniques based on the project requirements.

Locate Buried Pipes, Cables and Infrastructure

Depending on ground conditions and the characteristics of the target, GPR may help identify both metallic and non-metallic buried infrastructure. This can include:

  • Water and other service pipes
  • Non-metallic pipes and conduits
  • Underground cables
  • Concrete structures
  • Buried tanks
  • Subsurface voids
  • Large rocks and other anomalies

GPR findings can then be considered alongside other locating information to develop a more complete understanding of the site.

GPR Surveys Before Excavation and Construction

Excavation without sufficient knowledge of underground conditions can expose workers, infrastructure and project schedules to unnecessary risk. A GPR survey before ground disturbance can provide additional information to help plan the work.

Our pre-excavation GPR services can be incorporated into projects involving trenching, construction, civil works, infrastructure maintenance and other activities where subsurface conditions need to be investigated.

Improve Visibility Before Ground Disturbance

A GPR survey may help your team:

  • Identify potential underground obstacles before excavation
  • Reduce the likelihood of damaging buried infrastructure
  • Limit unnecessary or exploratory excavation
  • Plan excavation areas more effectively
  • Identify subsurface anomalies requiring further investigation
  • Make better-informed decisions about ground works

GPR is an investigative tool, and results can vary depending on soil composition, moisture, depth and the properties of the target. Our operators consider these factors when carrying out surveys and interpreting results.

Concrete, Void and Subsurface Investigations

Ground penetrating radar is not limited to underground utility locating. It can also be used to investigate certain structures and subsurface features where understanding what lies beneath or within a surface is important.

Depending on the project, GPR may assist with identifying concrete structures, voids, changes in material and other anomalies. These investigations can provide useful information for civil, agricultural, mining and infrastructure projects.

GPR for Civil and Infrastructure Projects

Civil contractors can use GPR as part of site investigation and excavation planning. Our services can help provide additional subsurface information before work begins, particularly on sites where existing infrastructure or unknown buried features may affect the project.

GPR for Agricultural Projects

Agricultural properties can contain buried pipes, irrigation infrastructure, tanks, conduits and other assets that may not be immediately visible. GPR can provide a non-intrusive method of investigating areas before new works, maintenance or excavation.

GPR for Mining Projects

Mining and associated infrastructure projects often require careful consideration of underground conditions. Our GPR capabilities can be incorporated into broader site investigation and locating requirements to help identify potential buried infrastructure and subsurface anomalies.

Areas We Service

Our GPR and underground locating services are available across Narrabri and surrounding regional areas, including projects throughout the wider 400 km service radius.

Our regional service coverage can support projects in and around areas such as:

  • Narrabri
  • Moree
  • Gunnedah
  • Tamworth
  • Dubbo
  • Coonabarabran
  • Wee Waa
  • Walgett
  • Coonamble
  • Other rural and regional NSW locations within our service area

If your project is outside these locations but falls within approximately 400 km of Narrabri, contact our team to discuss your requirements. We can confirm whether we can service your site.

Regional and Remote Site Support

Working across regional NSW means projects can often be located away from major centres. Powervac provides mobile services that allow our team to travel directly to project sites rather than requiring clients to transport equipment or assets elsewhere for investigation.

This makes our GPR services suitable for rural properties, civil construction sites, agricultural operations, mining locations and other regional projects where on-site investigation is required.

Experienced GPR and Underground Locating Specialists

Powervac brings more than 25 years of industry experience to underground locating and investigation work. Our operators hold CERTLOC certification and understand the importance of accurate locating, careful site assessment and safe work practices.

We take the time to understand the requirements of each project before determining the appropriate approach. This helps ensure the information gathered is relevant to the work being planned and can be used effectively by your project team.

Professional Service From Survey to Reporting

Our GPR service covers more than operating the equipment. We provide end-to-end support, including:

  1. Discuss your requirements – We learn about your project, site and investigation objectives.
  2. Assess the site – We consider site conditions and determine the appropriate survey approach.
  3. Carry out the GPR survey – Our operators conduct the investigation using suitable GPR methods.
  4. Interpret the findings – Survey information is assessed to identify relevant subsurface features and anomalies.
  5. Provide reporting – Where required, findings can be documented to support project planning and decision-making.

GPR Services Integrated With Underground Locating

At Powervac, GPR is provided as part of our professional locating and investigation services. We do not offer GPR equipment hire. Instead, our qualified team carries out the survey and provides the associated interpretation and reporting.

This gives clients a complete service rather than requiring them to operate unfamiliar equipment or interpret GPR data themselves.

A Practical Approach to Subsurface Investigation

Every site presents different conditions, and GPR results can be influenced by soil type, moisture, depth and the characteristics of buried materials. Our team considers these factors when planning and undertaking each investigation.

Where appropriate, GPR can also be used alongside other locating methods to provide a more comprehensive assessment of the site.
