This service is designed to support those involved in planning, design, construction, and maintenance across a wide range of projects. Fully conversant with PAS128:2022, we provide expert advice and consultation to ensure the most effective methodology is applied to meet our clients’ specific needs.

We utilise a range of GPR equipment to meet various project needs, including high-frequency scanners for concrete analysis and vehicle-mounted systems for large-scale highway data collection. This versatility allows us to tackle any challenge with precision. All GPR data is post-processed using the latest software, delivering both 2D and 3D results for comprehensive insights. We prioritise transparency with our clients, taking the time to clearly explain deliverables and ensuring they are always fully informed throughout the process.

Our Underground Utility Surveys can be used for:
• Detecting metallic and non-metallic services
• Full utility detection and mapping
• Subsurface/geophysical investigations
• Void detection/location
• Past site occupancy surveys
• Single service tracking

What is a Ground Penetrating Radar (GPR)?

Ground Penetrating Radar (GPR) is a non-intrusive geophysical technique used to image the subsurface. It employs multi-frequency antennas (ranging from 200 to 600 MHz) and multi-polarization technology to provide detailed and accurate images of the ground below.

The use of multiple frequency antennas allows for the detection of both shallow, small-diameter services and those buried at greater depths. Additionally, GPR surveys can identify voids or other buried obstructions that may be present.

The process works by transmitting an electromagnetic pulse into the ground. The radar then records the strength and the time it takes for the signals to return after interacting with different materials beneath the surface. This data provides vital insights into the composition and structure of the subsurface, ensuring safe and informed decision-making for your projects.
