Concrete & Rebar Scanning
Concrete and rebar scanning are completed using ground-penetrating radar (GPR), allowing engineers to map the hidden layout of steel reinforcement and internal features within concrete slabs, columns and walls.
About
GPR Concrete Scanning & Rebar Scanning Explained
This scanning technology is highly effective in detecting the presence, depth, and spacing of rebar, post-tension cables, and other embedded objects within concrete.
By producing real-time, non-invasive data, gound penetrating radar (GPR) surveys allow construction professionals to gain a clear understanding of what lies beneath the surface. Whether you’re planning to drill, cut, or core into concrete, scanning first ensures these activities are carried out safely, without damaging the structural elements or creating unnecessary hazards.

Concrete & Rebar Scanning with GPR Surveys
Construction-related issues can escalate quickly if potential risks go unidentified, often resulting in significant delays and unexpected costs. When it comes to working with reinforced concrete structures, accurately mapping the position of rebar and other embedded elements is crucial for ensuring safety and structural integrity.
Igne offers comprehensive GPR concrete scanning surveys, providing our clients with a safe, cost-effective solution to optimise and de-risk their construction projects.

Risks
The Risks of Not Doing Concrete & Rebar Scanning Before You Start Construction
Failing to conduct a GPR survey for concrete and rebar scanning before intrusive works begin can potentially lead to costly and dangerous outcomes such as:
Structural Damage
Accidentally cutting through rebar or post-tension cables can compromise the structural integrity of the building, leading to expensive repairs or even project abandonment in extreme cases.
Worker Safety
Cutting into concrete without scanning first can put workers at risk of injury, especially if they unknowingly strike rebar, electrical conduits, or other embedded objects.
Costly Delays
Unexpected obstructions or damages discovered during construction can cause significant project delays. This can be especially problematic on sites with tight schedules or complex, multi-phase developments.
Increased Liability
Damage to structural elements, utilities, or embedded services can lead to legal and financial liability for contractors and developers. Conducting a GPR scan minimises these risks by providing detailed, actionable insights before work begins.
By scanning first, Igne helps you mitigate these risks, ensuring that your project proceeds safely and efficiently.
Process
How Concrete & Rebar Scanning Is Done Using GPR
GPR technology is a non-invasive method used to detect and map the internal structure of concrete. During a concrete and rebar scanning survey, high-frequency radio waves are emitted by the GPR equipment, which penetrate the concrete surface. These waves are reflected back when they encounter materials like rebar, post-tension cables, or voids.
The reflections are captured and analysed to create a detailed image of the subsurface structure.
Igne’s specialists interpret this data to accurately locate the rebar and other embedded objects, providing clear information on their depth, spacing, and orientation. The non-destructive nature of GPR makes it ideal for concrete scanning, as it leaves the structure intact while offering high-resolution data in real-time.
Design & Plan
Designing & Planning a Concrete Scanning Survey
At Igne, we tailor each concrete and rebar scanning survey to meet the specific needs of your project. We start by assessing the site and understanding the scope of work. This includes reviewing any existing structural drawings or information about the building to identify key areas for investigation.
Once the site assessment is complete, we create a customised survey plan, focusing on areas where intrusive works are planned, such as drilling, coring, or cutting. The GPR scanning process is then carried out by our skilled technicians, ensuring full coverage of the target areas.
After the scan, our team processes the collected data and compiles a detailed report, highlighting the exact location of rebar, post-tension cables, or other embedded elements. This report is essential for project planning, helping you avoid any surprises once construction begins.
Benefits
Benefits of GPR Surveys for Concrete & Rebar Scanning
Concrete and rebar scanning using GPR offers numerous benefits, helping to optimise project planning and improve safety:
Non-Invasive & Non-Destructive
GPR scanning allows for accurate mapping of rebar and embedded objects without damaging the concrete structure, making it a cost-effective and safe option.
Real-Time Results
GPR surveys provide immediate feedback, allowing for quick decision-making on-site. This minimises delays and helps streamline project timelines.
Comprehensive Data
GPR can detect a range of embedded objects, from rebar to post-tension cables and even voids within the concrete. This comprehensive data helps you avoid costly errors during intrusive works.
Increased Safety
Knowing the precise location of rebar and other objects ensures that workers can safely drill, cut, or core into the concrete, reducing the risk of accidents or injuries.
Cost Savings
By identifying potential obstructions before they become a problem, GPR surveys prevent costly project delays and repairs.

Frequently Asked Questions about Concrete & Rebar Scanning GPR Surveys
- What can GPR detect in concrete?
GPR can detect a variety of embedded objects within concrete, including rebar, post-tension cables, electrical conduits, voids, and other structural elements.
- How accurate is GPR for concrete scanning?
GPR is highly accurate in locating rebar, cables, and other embedded objects. However, factors such as the density of the concrete and the presence of moisture can affect the precision of the results.
- Is concrete scanning necessary before drilling or cutting?
Yes, concrete scanning is essential to avoid damaging rebar, electrical conduits, or post-tension cables, ensuring that the structure remains intact and that workers are not put at risk.
- How long does a concrete and rebar scanning survey take?
The duration of a GPR survey depends on the size and complexity of the site, but most surveys can be completed within a day. Data analysis and reporting typically take a few additional days.
- Is GPR safe for the environment?
Yes, GPR is a non-invasive, environmentally friendly technology that does not disturb the structure or the surrounding environment.
