Using GPR for Rebar Surveys and Concrete Scanning
At Red Laser Scanning, our strategic choice to employ Ground Penetrating Radar (GPR) for rebar surveys and concrete assessments.
Ground Penetrating Radar (GPR) stands out as an incredibly versatile tool, making it a preferred choice for rebar surveys and concrete assessments. Its non-invasive and non-destructive nature allows it to safely and accurately measure concrete thickness, analyse rebar, and determine concrete structure details. With the ability to detect reinforcing steel bars and other features in concrete up to a depth of 50cm, and sometimes even greater, GPR excels in providing in-depth insights. Moreover, its capacity to identify multiple layers of reinforcement and its compact size, allowing detection within 10cm of an obstruction, simplifies the scanning process.

Rebar CAD Drawings
These results serve multiple purposes, from confirming as-built drawings and determining reinforcement details when drawings are unavailable to facilitating structural assessments. Prior to construction, a concrete survey is indispensable, effectively minimising costly errors and ensuring the safety and efficiency of your project.

On-site mark-up survey
Our On-Site Mark-Up Concrete Scanning Survey is a highly effective solution tailored for projects where immediate, precise on-site action is required. By leveraging Ground Penetrating Radar (GPR) technology, we detect the precise locations of rebar, pipes, and other critical features. We mark their location directly on walls, floors, or columns using chalk or special paint. This meticulous process ensures contractors receive precise guidance, minimising the risk of disruptive incidents during cutting and drilling operations, especially when dealing with structural reinforcements. Whether for small or expansive areas, our on-site mark-up survey remains efficient and effective, with the advantage of immediate real-time data application and no need
for off-site processing.
Ferro scanning for rebar detection
To conduct meticulous structural examinations, our team employs Ferro scanning. Ferroscan is a portable device used for rebar mapping that provides immediate, on-the-spot insights into the reinforcement present within the surveyed region.
Ferro scanning excels in determining crucial details such as cover depth, bar diameter, and bar spacing, as well as mesh layout.
There are two primary modes of operation for Ferro Scanning: Ferroscan Quickscans and Ferroscan Image Scans.
Example of the Ferro scanning data showing rebar grid
- Precisely locate reinforcing bars and their cover depth, oriented perpendicularly to the scan’s direction.
- Multiple scans, each up to 10 meters in length, are conducted for comprehensive data.
- This method allows direct marking of rebar positions on the concrete surface with visible mediums like chalk or paint sticks.
- Ideal for project planners preparing for concrete drilling or coring.

Ferroscan Image Scans
- In-depth insights into reinforcement within the surveyed areas.
- Generates complete images of the reinforcement network, revealing crucial information about reinforcement arrangement, position, cover depth, and indicative bar diameter.
- These high-quality images are available for assessment through transverse or longitudinal sections, providing depth-specific ‘slices’ and generating statistical data.
- Post-survey, data can be transferred to a computer for thorough analysis.
- These images can seamlessly integrate into reports or CAD drawings, facilitating a comprehensive and data-enriched understanding of the surveyed area’s structural integrity.

Frequently Asked Questions (FAQs) about Concrete Scanning
Concrete scanning is a non-destructive technique that uses advanced technology, such as Ground Penetrating Radar (GPR), to penetrate concrete surfaces and detect objects, anomalies, and structural details hidden beneath the surface.
Concrete scanning can detect a wide range of crucial information, including rebar placement, voids, cracks, non-ferrous services like pipes and conduits, changes in surface, and even the thickness of concrete slabs.
Rebar survey is essential for assessing the location, spacing, and condition of reinforcement bars (rebar) within concrete structures. It ensures safety, prevents damage during drilling or cutting, and confirms compliance with construction standards.
We employ advanced concrete scanning technology, particularly Ground Penetrating Radar (GPR), to test for rebar in concrete. GPR emits radar waves that bounce off rebar, allowing us to visualize and map its precise location within the concrete.
Concrete scanning works by sending electromagnetic waves or sound waves into concrete structures. When these waves encounter different materials or anomalies within the concrete, they reflect back to a receiver. By analysing these reflections, we create detailed images and reports.
Concrete scanning technology is indispensable for construction and renovation projects. It enhances safety by identifying hidden hazards, saves time and costs by preventing damage to utilities and rebar, and ensures the structural integrity of concrete structures. It’s an indispensable tool for informed decision-making in the construction industry.
