Ground Penetrating Radar GPR Surveys

Twenty20 Surveys

At Twenty20 Surveys, we possess significant proficiency in conducting GPR surveys across various projects, encompassing both modest residential properties and large-scale commercial portfolios. Our advantage lies in the diverse array of GPR Systems at our disposal, ensuring that we employ the most suitable system for each specific task.


At Twenty20 Surveys, we are proud to offer extensive expertise in GPR (Ground Penetrating Radar) surveys for a wide range of projects. Whether you have a small residential property or a major commercial portfolio, we have the knowledge and equipment to provide accurate and comprehensive GPR survey solutions.

Ground Penetrating Radar is a non-destructive geophysical method used to detect and locate subsurface features and utilities. It is a valuable tool for mapping and assessing underground structures, pipes, cables, voids, and other subsurface elements.

Our team of experienced surveyors is well-versed in the application of GPR technology and understands the intricacies of interpreting GPR data. We have a full arsenal of different GPR systems, allowing us to select and utilise the most appropriate system for your specific project requirements.

By using the correct GPR system, we can effectively penetrate the ground and collect high-resolution data that provides valuable insights into the subsurface conditions. Our comprehensive GPR surveys help identify potential hazards, assess structural integrity, and aid in the planning and design of construction projects.

Whether you need GPR surveys for utility mapping, archaeological investigations, concrete inspections, or any other application, we have the expertise and equipment to deliver accurate and reliable results. Our team works diligently to ensure that our GPR surveys are conducted efficiently and provide you with the information you need to make informed decisions.


Choose Twenty20 Surveys for your GPR survey needs, and benefit from our extensive expertise, advanced equipment, and commitment to delivering high-quality results. Contact us today to discuss your project requirements and discover how our GPR surveys can support your objectives.

Ground Penetrating Radar Applications

The following list of Ground Penetrating Surveys offered by Twenty20 Surveys demonstrates some of the more common GPR applications for the construction industry: 


Construction detail surveys:

A Ground Penetrating Radar survey can determine the general construction arrangement, including changes in material type, location of structural steelwork and layer thickness.


Concrete mapping surveys:

Ground Penetrating Radar can be used to inspect concrete floors, walls, decks, slabs, tunnels, balconies, warehouses and garages. It can locate and map rebar, tendons and conduits at a higher resolution and at greater depths than most other survey methods.


Chimney flue location surveys:

Ground Penetrating Radar offers a quick and non-intrusive method of locating and mapping chimney flues. The results can either be marked-up on-site or CAD drawings.


Floor slab surveys:

A rapid means of determining general slab construction detail, including reinforcement distribution and slab thickness. Ground Penetrating Radar can also detect voids below slabs and map their extent, thereby identifying potential problems in heavily trafficked slabs, such as warehouses before failure occurs.


Embedded steel location:

surveys to locate embedded steel in masonry. Particularly suitable for the characterisation of historical and listed buildings due to the survey being non-intrusive.


Roads, runways and pavement surveys:

GPR can determine pavement thickness (asphalt and concrete), detect voids underneath the road pavement, identify de-bonding between layers and determine layer thickness.


Buried object location:

Ground Penetrating Radar survey can locate underground storage tanks (UST), grave location, forensic investigations and a wide variety of other buried objects.


Utility surveys:

Ground Penetrating Radar is the only non-destructive technology that can identify non-metallic as well as metallic subsurface utilities. It is suitable for the location of services including water, sewer, gas, electric, telephone and fibre optic.


Hazardous waste:

Having successfully located buried pipes, drums and underground storage tanks, Ground Penetrating Radar can, under the right conditions, be used to identify the extent of any leakage and contamination.


Foundation investigation surveys:

Ground Penetrating Radar is a useful tool for the location, investigation and determination of the extent of footings and foundations.
