GPR Surveys
Get in TouchAt Nicholls Surveying, we provide expert GPR surveys to deliver precise subsurface insights. Ground Penetrating Radar (GPR) is a non-invasive method that uses radar pulses to image the subsurface, ideal for identifying utilities, voids, and other underground features.
Our surveys cater to a variety of clients including construction companies, utility providers, and archaeologists. We cover and the surrounding areas.

How Much Does a GPR Survey Cost?
A GPR survey typically costs between £500 and £1,200. The price is influenced by several key factors: the survey area size, depth requirements, and site conditions.
Additionally, specialised equipment such as the GPR antenna frequency, which can range from 100 MHz to 1,000 MHz, plays a role in determining costs. Lower frequencies penetrate deeper but may provide less detail, whereas higher frequencies offer more detailed readings but shallower penetration.
We also consider the complexity of the survey location, such as urban areas with heavy utility networks, which might require advanced data interpretation methods like radar tomography. Larger or more complex sites may incur higher costs, while straightforward surveys for smaller areas fall at the lower end of the scale.

What Are the Benefits of GPR Surveys?
GPR surveys offer several key benefits, including:
Non-invasiveness: Causes no damage to the surveyed area, preserving even delicate surfaces like historic pavements or landscaped gardens.
Precision: Provides detailed images of underground utilities and features, identifying anything from electrical lines to concrete support structures. Using a range of frequencies, we can achieve resolution between 0.1 to 1 metre, adaptable to various site conditions.
Versatility: Useful for construction, archaeology, and utility location. In construction, GPR surveys can map the rebar layout in concrete slabs, while in archaeology, they can locate ancient artefacts without disturbing the soil.
Safety: Minimises the risk of striking buried utilities during excavation. This aligns with 's local safety regulations, reducing the potential for costly project delays.
Our use of GPR technology ensures reliable results tailored to your needs. Get in touch to explore how a GPR survey can benefit your project.
How Long Does a GPR Survey Take?
Most GPR surveys are completed within one to two days, depending on the survey size and complexity. For instance, a survey covering an area of around 1,000 to 2,000 square metres usually requires one day for fieldwork.
Larger areas or complicated conditions, like those with mixed sub-surface materials, may extend the time needed to two days. We use precisely calibrated GPR equipment, ensuring thorough scanning up to depths of approximately 5 metres, while adhering to industry standards such as PAS 128 for mapping underground utilities.
In addition, processing the data captured in the field and delivering a report takes another one to two days. We conduct in-depth analysis using specialised software to interpret the radar data, identifying features like voids, pipes, and rebar.
We strive for efficiency without compromising accuracy, ensuring reliable results for diverse clients from construction firms to utility companies.
What Does a GPR Survey Cover?
GPR surveys cover a wide range of underground features, such as buried utilities, voids, pipes, and soil structures. This technology uses electromagnetic radar pulses to detect and map subsurface elements, with frequencies typically ranging from 100 MHz to 2.6 GHz, allowing us to survey depths of up to 30 metres.
Our surveys are particularly useful for projects involving site redevelopment, underground construction, and archaeological investigations. We apply GPR technology to identify discrepancies in ground composition, which is vital for avoiding disruptions during excavation.
Our experienced team often collaborates with geotechnical engineers to interpret the GPR data, ensuring accuracy and relevance in different environments. We ensure a thorough examination to support informed decision-making in your project.
