      Concrete Scanning and Rebar Location

      Here at Red Laser Scanning, we’re proud to dedicate an entire department to the art of Concrete Scanning and Rebar Mapping. Concrete scanning is a non-destructive, high-tech craft that employs cutting-edge technologies like Ground Penetrating Radar (GPR) and electromagnetic waves to unveil the hidden features beneath the surface of concrete structures. Through our expertise, we bring forth essential details, revealing the precise locations of rebar, post-tension cables, conduits, voids, and other concealed elements. Our approach ensures safety, bolsters structural integrity, and streamlines project planning.

      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.

      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.

      Ferroscan Quickscans

      • 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.

      Great firm who go the extra mile to meet customer requirements and deadlines with superior output! Highly recommended.
      Marina Martynenko
      I have never seen a laser scanning service more efficient and easy-going such as Red Laser Scanning. Scanned was made the same week I received the quote and the drawings were here 3 days later. Very good company who deliver quick but quality results.
      Kerstin Stockreiter
      We hired red laser for our building site and needed a measured survey. The team were really professional and friendly. I have hired a few companies in the past for a measured survey and found these guys not only did an excellent job but we also got our plans delivered back to us within days. Thanks!
      Rikhil Shah
      We have asked Red Laser Scanning to do our floor plans and point cloud for our planning application. Very professional service and Dimitri was very friendly when he came to do the survey. Also competitive pricing. Would recommend!
      Lana Begalova
      Very good service! I was looking for a company which can do measured survey for my house in order to obtain planning permission. My architect quoted me twice more for existing plans. I came across Red Laser Scanning and booked the survey for the next day and received drawings three days after. Highly recommended!

      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.
