Ground Penetrating Radar (GPR) Surveys

Gain subsurface insights safely and efficiently with our advanced GPR surveys, revealing hidden utilities, voids and archaeological features to help you make informed decisions.

What is a Ground Penetrating Radar (GPR) survey?

Ground Penetrating Radar (GPR) surveys are non-destructive radar imaging tools that produce accurate subsurface data without the need for digging or drilling.

Engineers send high-frequency radio waves into the ground or structure, which reflect when they hit objects or materials with certain properties. This allows surveyors to gain knowledge about subsurface conditions and determine how this will affect a project going forward.

Safe surveying

Due to the use of non-invasive radio waves, GPR is a completely safe surveying technique for public spaces or occupied buildings. These radio waves are also completely harmless, posing no radiation hazard to on-site workers.

What is GPR used for?

GPR is used to identify qualities of the ground underneath a work site or hidden features of a structure. It can discover:

Utilities like water pipes or fiber-optic ducts.
Sinkholes and cavities
Structural integrity
Archaeological anomalies
Environmental concerns

What data does GPR deliver about these features?

GPR gathers a range of data for specialist interpretation, including raw radagrams, 2D depth profiles, 3D subsurface models, CAD & GIS layers, and BIM integration.

What do GPR surveys provide?

This data gives Project Managers complete clarity before starting a major project that plans can go ahead safely. It can even improve efficiency by assuring Site Leads that it’s safe to speed up phases of a project, saving time and resources.

Being able to prevent major utility strikes or structural catastrophes before work begins improves company reputation and assists in being relied upon for more projects down the line. This kind of verification also provides legal satisfaction and ensures that moving forward, your project is completely compliant.

What sectors do GPR surveys support best?

The sectors that we support with GPR surveys the most are:

Construction

We use GPR surveys to map rebar and post-tension cables. This prevents utility strikes before machinery starts breaking ground.

Environment

Before environmental projects, we scan for hidden voids, sinkholes, and soil subsidence, as well as mapping bedrock levels or locating buried hazards.

Heritage

The non-invasive nature of GPR surveys is crucial to the success of heritage projects. By successfully scanning a heritage site or structure without having to use destructive methods, projects can be properly surveyed for ancient foundations, crypts, or graves without disturbing protected landmarks.
