GPR Surveys

Subvision Surveys is SSIP and ISO accredited, and continues to invest in the latest GPR equipment to serve clients across a wide range of industries. We’re trusted by Tier 1 contractors, developers, planners and private individuals nationwide for accurate, reliable subsurface data.

Our GPR surveys work by sending high-frequency radio waves into the ground via an antenna. Our experienced team records the signal as it reflects back, identifying variations that indicate buried objects or utility services. GPR surveys are effective in locating buried services, voids, tanks, obstructions and more.

The Advantages of GPR Surveys

GPR is non-invasive and non-destructive, allowing detailed subsurface imaging without disrupting the ground. Subvision Surveys provides high-precision, high-resolution surveys, ideal for accurately locating small objects and detailed structures such as underground utilities, reducing development risk and helping optimise project timescales. Further information can be found in our FAQs below.

Getting the Most Accurate Results

We also provide a wide range of surveying methods, covering both above and below ground survey solutions. For the most comprehensive and accurate underground utility survey, we recommend combining GPR with electromagnetic surveys, as GPR depth penetration can vary depending on ground conditions from excellent performance in dry, sandy soils to more limited penetration in moist or clay soils with higher electrical conductivity.

GPR SURVEY FAQ’S

A GPR survey uses Ground Penetrating Radar technology to detect and map features beneath the ground without excavation. High-frequency radio waves are transmitted into the surface, and our equipment records variations as these waves reflect back, indicating buried utilities, voids, tanks, foundations and other underground structures. This gives surveyors a detailed picture of what’s below ground with a high level of accuracy, without the time, cost or disruption of physically digging to find out. GPR is widely used across construction, utilities and infrastructure projects wherever an accurate understanding of subsurface conditions is needed before work begins.

GPR surveys are commonly carried out before construction, excavation and redevelopment projects, wherever there’s a need to understand what lies beneath a site before work begins. They help identify hidden underground features early, reducing the risk of delays, unexpected discoveries and damage to existing infrastructure during groundworks. A GPR survey is often required as part of due diligence before piling, drilling or trenching, and can also support planning applications, feasibility studies and design work by giving architects and engineers reliable, accurate information about existing site conditions from the outset.

Ground Penetrating Radar surveys can locate underground utilities, buried foundations, concrete slabs, voids, storage tanks, drainage systems and other subsurface objects. The results help provide a clearer understanding of site conditions before work begins, reducing the risk of unexpected obstructions or hazards during construction. Because GPR detects changes in subsurface material rather than relying on a single detection method, it can identify both metallic and non-metallic features, making it a versatile option for sites where a wide range of buried infrastructure may be present, and where other detection methods alone may not be sufficient.

Yes, GPR surveys are completely non-invasive and non-destructive. The technology gathers detailed underground information without disturbing the ground, making it an ideal solution for projects where excavation is impractical, costly or should be avoided entirely, such as on live sites, within occupied buildings, or in areas of historical or environmental sensitivity. Because no digging is required, GPR surveys can typically be carried out quickly with minimal disruption to ongoing site activity, allowing accurate subsurface information to be gathered without delaying other works taking place on or around the survey area.

GPR surveys provide highly accurate subsurface data when completed by experienced surveyors using advanced equipment. Survey performance can vary depending on ground conditions, such as soil type and moisture content, which affect how well radar signals penetrate and reflect back. This is why GPR is often combined with electromagnetic locating for the most reliable results, particularly on complex sites or where ground conditions are less favourable. Experienced interpretation of the data is just as important as the equipment itself, ensuring results remain accurate and dependable even where conditions make detection more challenging.

Following the survey, you’ll receive clear drawings and detailed reports highlighting detected underground features, including their approximate location and depth. The survey information can be used to support planning, design, excavation and construction while reducing the risk of unexpected site issues once work is underway. Reports are provided in a format that’s straightforward for architects, engineers and contractors to work with directly, giving your project team the confidence to plan groundworks accurately rather than relying on assumptions or incomplete historic records of what may be present below ground.

Subvision Surveys combines decades of industry experience with the latest Ground Penetrating Radar technology to deliver reliable results across the UK. Our skilled surveyors provide accurate, high-quality data and professional support for projects of every size, from small residential jobs through to major commercial and infrastructure developments. We’re SSIP and ISO accredited, and our team is trusted by Tier 1 contractors, developers and planners nationwide. Because GPR often works best alongside other detection methods, we can also combine it with electromagnetic locating or further utility surveys where a site calls for it.
