GPR Surveys London
GPR Survey Experts
Turner Baker offers Ground Penetrating Radar surveys (otherwise known as ‘GPR’) in London and the rest of the UK. We have over 20 years of experience in the Construction Industry working on all types of properties from new build and commercial properties, to ancient cottages and castles.
Our qualified engineers use Ground Penetrating Radar technology to survey floors and vertical walls and can provide our client with clear information on:
- Flue routes on internal, external and party walls
- The location of utilities and within walls and floors
- The location of rebar within cast concrete
- Identifying voids within walls and floors
A Ground Penetrating Radar survey can offer valuable information for many different types of project. For older properties, this may be tracking flue routes through a building or locating pipes buried in walls. In newer properties, GPR surveys are useful for identifying steels and reinforcing bars. All of our utility mapping surveys are undertaken by qualified engineers with experience of working in the construction industry.
The results of a GPR survey can be provided in whatever format is most suitable for the project – we can mark up areas on walls and floors on-site or provide annotations to existing CAD drawings for use at the design stage of a scheme.

What is a Ground Penetrating Radar Survey?
A GPR survey uses radar to scan walls or floors which detects changes in density within the structure. The GPR technology that we use at Turner Baker allows us to scan to a depth penetration of 450mm.
We work extensively within the construction industry, particularly on renovation projects, offering our underground utility surveys to provide detailed information on the location of flues, pipework, utilities and steels within walls and floors.
This technology has proved particularly useful for renovation projects in townhouses with party walls to ensure that no damage is caused to neighbouring properties.
Our Ground Penetrating Radar surveys in London and the rest of the UK include:
- Scanning walls or floors using radar.
- Detecting changes in density within the structure.
- Depth penetration of 450mm.
- Scanning for utilities within walls and floors.
- Rebar within cast concrete.
- Flues and voids within walls and floors.
Why do you need a Ground Penetrating Radar Test?
GPR surveys are an invaluable tool to provide critical information on what flues, pipes and steels are located within a wall and the direction in which they run. This allows plans to be put in place to prevent damage to concealed utilities during any maintenance or alterations being carried out within a property.
This is particularly useful in terraced or semi-detached properties where boundaries are shared to ensure that no damage is done to party walls.
Wall depths can also be measured to provide information for structural calculations.
It can also be useful to use GPR to locate redundant hidden flues that can then be re-purposed for utilities.

Our GPR Survey Applications
Turner Baker has provided GPR surveys for various purposes. We are regularly commissioned to map flue routes within properties – identifying where a flue runs through a property from the fireplace up to the chimney (chimney flue location surveys).
We have also carried out utility mapping surveys to locate steels within walls and floors and find utilities. Ground Penetrating Radar surveys have also been carried out to locate asbestos flues within walls and locate and verify rebar within concrete (concrete mapping surveys).
GPR Survey Inspections In London
A Ground Penetrating Radar survey is carried out using a handheld mobile unit which requires one person to operate it. For ease of use, the unit is battery-powered and doesn’t require a mains connection. The unit can be operated at a height of up to 4 metres with the ability to go higher if operated from a scaffold platform.
The time it takes to carry out a GPR survey is dependent on the size of the property. All GPR surveys are non-intrusive which makes them particularly useful for investigations in historic and other sensitive buildings.
The data collected during the utility survey is analysed using Raydan 7 software. It can be imported onto .dwg files allowing us to provide new CAD drawings or annotate the information onto existing drawings. We can also mark up the location of flues, steels and other pipework and cabling directly onto walls on site, which is particularly useful in refurbishment projects when conducting utility surveys.
The ability to map utilities within walls is particularly useful. We can locate the position of cables and pipework which allows maintenance or structural changes to be made to walls without fear of damaging any utilities.
Enquire About Our GPR Surveys In London
We carry out Ground Penetrating Radar surveys anywhere in London and across the UK. If you are carrying out a renovation project and need to know where flues run up through a property or where utilities are located then a GPR survey can help.
You may have queries about the construction of a party wall – a GPR survey can provide detailed analysis.

Frequently Asked GPR Survey Questions:
Why is a GPR test useful?
A GPR survey is useful for identifying flue routes in a property and for locating steels, pipes, cabling and voids within walls and floors. When carried out before renovations are undertaken, GPR can provide valuable information to avoid damaging flues or any facilities that are located in walls or under the floor.
How much does a GPR survey cost?
The cost of a GPR survey is based on the area that needs to be scanned and how the information is delivered. Each GPR survey is quoted individually as the cost of a survey is based on the number of walls and the area that needs to be scanned and the delivery method required – whether marked up on-site or using CAD drawings.
How deep can a GPR survey go?
The GPR technology that we use is effective to a depth of 450mm. This allows us to carry out surveys on walls and floors in both domestic and commercial settings.
What areas do you offer your GPR Survey?
Turner Baker offers GPR surveys nationwide. We work extensively in London and have surveyed properties all over the UK from Cornwall to the most Northern parts of Scotland.
