Towed GPR Surveys

Towed Ground Penetrating Radar (GPR) surveys are an efficient method for investigating subsurface conditions across large areas, ideal for projects where speed and coverage matter as much as accuracy.

The GPR equipment is towed behind a vehicle or manually along the ground, allowing rapid data collection across expansive sites, from road corridors and pipelines to large development plots, without the need for excavation. This makes towed GPR particularly effective where standard GPR surveys would take considerably longer to cover the same ground.

Towed GPR vs Standard GPR

Standard GPR surveys are typically carried out by walking the equipment across a site in a grid pattern, well suited to detailed, targeted areas. Towed GPR covers significantly more ground in the same amount of time, making it the better option for long, linear sites or large open areas where a full grid-based survey would take considerably longer to complete. Our team can advise which method is right for your site, or combine both where a project calls for detailed coverage in some areas and rapid coverage across the wider site.

Where Towed GPR Is Most Effective

Towed GPR is particularly effective on road corridors, pipeline routes, airfields, large development plots and other sites where speed and coverage are priorities. Because data is collected continuously as the equipment moves, we’re able to survey substantial areas in a fraction of the time a walked survey would take, without compromising the quality of the data collected.

Why Choose Subvision for Towed GPR Surveys

Subvision Surveys is SSIP and ISO accredited, and our team has delivered towed GPR surveys for Tier 1 contractors, developers and planners across the UK. With more than 3 decades of experience, we provide a vast range of surveying solutions to clients across Essex, the South East and nationwide, using specialised techniques and cutting-edge equipment to deliver accurate results at competitive rates for Tier 1 contractors, developers, planners and private individuals alike.

Beyond large-area coverage, our team also carries out more targeted GPR work, including GPR Concrete Inspection, where the focus shifts from mapping a wide corridor or open site to identifying hazards, reinforcement and voids within a specific concrete structure. Whether your project needs rapid coverage across a large site or precise, structure-specific detection, we apply the right method to suit, rather than a single standard approach regardless of scale.

TOWED GPR SURVEY FAQ’S

At Subvision Surveys, our Towed GPR surveys provide a non-intrusive way of investigating what is beneath the ground surface. Using specialist Ground Penetrating Radar (GPR) equipment, our experienced surveyors can scan large areas efficiently to identify and map potential underground features. Our Towed GPR system is particularly useful for larger sites where detailed subsurface information is required across a wide area. By combining modern surveying technology with our team’s practical experience, we can provide clear and reliable information to help our clients understand what is beneath their site before excavation, construction or other groundworks begin.

Our Towed GPR surveys can help identify a range of buried features and potential underground anomalies without the need to excavate the ground. Depending on the site conditions and the depth and size of the feature, our team can investigate for items such as buried services, structures, voids, chambers and other changes beneath the surface. We use specialist GPR technology to collect detailed information across the survey area, helping us build a clearer picture of what may be present underground. Our findings can provide valuable information for architects, engineers, developers, contractors and other professionals planning work on or around a site.

We use Towed GPR surveys where our clients need efficient subsurface investigation across larger areas. Unlike traditional intrusive investigation methods, GPR allows our team to survey the ground without immediately disturbing the surface. Our Towed GPR system can cover areas efficiently while collecting valuable information about potential underground features. At Subvision Surveys, we combine this technology with our team’s surveying experience to provide dependable results tailored to the requirements of each project. Whether you’re investigating a development site, commercial area, road, car park or other large surface, we can help provide a better understanding of the ground before work begins.

Our Towed GPR surveys can be useful for a wide range of domestic and commercial clients who need to understand what may be beneath an existing surface. We work with professionals including developers, engineers, contractors, architects and other construction and property specialists. Our surveys can be particularly valuable on larger sites where covering a significant area efficiently is important. Before we begin, our team takes the time to understand your project and what information you need from the survey. This allows us to select an appropriate surveying approach and provide information that can support your planning, design and construction decisions.

Our team can use Towed GPR surveying across a variety of sites and surfaces where investigating below ground is required. Depending on the project, this can include areas such as roads, car parks, development sites, industrial premises, commercial land and other large open surfaces. The suitability of GPR will always depend on the individual site conditions and the information required, which is why we assess each project carefully. At Subvision Surveys, our experienced surveyors can discuss your requirements with you before the survey takes place, helping us determine the most suitable approach for investigating your site.

Our Towed GPR surveys use specialist radar equipment that is moved across the survey area to collect information from beneath the ground surface. As our team moves the system across the site, radar signals are transmitted into the ground and the returning information is recorded for analysis. Our experienced surveyors then process and interpret the collected data to identify potential subsurface features and anomalies. The exact results will depend on factors such as ground conditions, material types and the depth and size of any buried features. We use our surveying experience alongside modern technology to produce useful information from the data collected.

At Subvision Surveys, we combine modern surveying technology with more than 3 decades of experience to provide professional surveying services for domestic and commercial clients. Our team understands that every site is different, which is why we take the time to understand your requirements before carrying out any survey. With our specialist Towed GPR equipment and experienced surveyors, we can investigate large areas efficiently and provide clear information about potential features beneath the surface. From initial discussions through to completing the survey, our focus remains on accuracy, professionalism and clear communication, giving you dependable information that can help you plan your project with greater confidence.
