Accurate Utility Mapping
Precisely locate and map underground utilities like water pipes, electrical cables, and sewer lines to ensure safe excavation and avoid accidental damage.
Ground Penetrating Radar (GPR) is a non-destructive subsurface scanning method that uses high-frequency radio signals to detect and map buried utilities, structures, and voids. Without breaking the surface, GPR provides clear, real-time visuals of underground conditions—ideal for planning excavation, construction, or asset management.
From reinforced concrete to clay and rock layers, GPR can detect both metallic and non-metallic objects. At Rapid Vac Trucks Wollongong, we use this advanced technology to support vacuum excavation and NDD services—offering safer, smarter decisions for utility locating and site preparation.

Ground Penetrating Radar (GPR) operates by sending electromagnetic waves into the ground. These waves reflect back when they encounter buried objects or material changes. The GPR system records these reflections, and the time it takes for the signals to return is analysed to create a detailed map of subsurface features.
This technique is highly effective for detecting various underground structures, providing accurate and dependable data for excavation and surveying projects.


Precisely locate and map underground utilities like water pipes, electrical cables, and sewer lines to ensure safe excavation and avoid accidental damage.
Identify embedded objects such as rebar and conduits within concrete structures, crucial for safe and precise drilling or cutting operations.
Identify underground storage tanks, pipelines, and potential contamination zones to evaluate environmental risks and ensure safe excavation planning.
Investigate and document historical sites non-invasively, maintaining the integrity of archaeological remains.
GPR offers detailed insights into subsurface conditions without requiring excavation, ensuring the site remains undisturbed.
Our technology provides accurate data on metallic and non-metallic objects, minimising the risk of utility damage.
Avoid unexpected repair costs and project delays by detecting underground issues prior to excavation.
Minimise risks to workers and the public by accurately identifying and avoiding underground hazards.
Obtain a comprehensive understanding of subsurface conditions to support informed decision-making and effective project planning.

GPR is used to detect and map underground utilities, structures, and anomalies without disturbing the soil. It is commonly employed in utility locating, environmental assessments, concrete scanning, and archaeological surveys.
GPR provides outstanding accuracy in detecting both metallic and non-metallic utilities, offering detailed visuals and precise depth readings. However, its performance can be affected by soil conditions and the materials being scanned.
Yes, GPR can detect non-metallic objects like plastic pipes, voids, and other subsurface features, making it versatile for various applications beyond locating metal utilities.
The depth GPR can reach depends on the radar wave frequency and soil conditions. Generally, GPR can penetrate several metres, with higher frequencies providing better resolution for shallow targets and lower frequencies ideal for deeper exploration.
Yes, GPR is a non-invasive and environmentally friendly method. It uses low-energy electromagnetic waves, leaving the ground and surrounding structures undisturbed, making it a safe choice for various applications.
