Concrete and Rebar Scanning
What is The Land and Topographic Survey
Concrete and Rebar Scanning is used to inspect concrete slabs, columns, and floors prior to caulking or drilling during renovation and new construction projects. Our concrete scans utilize ground penetrating radar (GPR) technology, ensuring fast and accurate inspections. GPR is a safe and non-invasive method. Using transmitted waves and their reflected signals, we can assess the subsurface to identify embedded objects. A concrete scan can provide project engineers with important details about the depth of the concrete, the presence of objects within the concrete, and any air pockets that may be undetectable from the surface.
When is Concrete and Rebar Scanning Necessary:
Often, residential or commercial property renovation projects require concrete covering or trenching (cutting) to relocate plumbing and utility lines. Our concrete and rebar scanning services use advanced technology and technical expertise to prevent costly damage to foundations, columns, or structural elements. Covering or cutting concrete without prior scanning can result in partial or complete damage to foundation beams, electrical conduits, plumbing, rebar, or structural post-tensioned cables.
In cases where construction assessment or retrofitting is necessary to evaluate the load-bearing capacity of aging reinforced concrete structures, and the original blueprints are missing, our concrete and rebar scanning services can reveal the configuration of the reinforcing steel, including rebar diameters, depth, and orientation.

Designing and Planning a Concrete and Rebar Scanning Survey
At National Line Survey, we customize each concrete and rebar scanning survey to meet the unique requirements of your project. Our process begins with a thorough site assessment and a clear understanding of the scope of work. This includes reviewing any available structural drawings or building information to identify critical areas for examination.
After completing a site assessment, we develop a tailored survey plan that emphasizes areas designated for intervention activities, including drilling, coring, or cutting. Our experienced technicians then perform the GPR scanning process, ensuring comprehensive coverage of the targeted areas.
After scanning the concrete and rebar, our team processes the collected data and compiles a detailed report, highlighting the exact location of rebar, post-tension cables and tendons, or other embedded elements. This report is essential for project planning, helping you avoid any surprises once construction begins.
Concrete and rebar scanning is performed with ground-penetrating radar (Proceq GPR), enabling engineers to see hidden arrangements of steel reinforcement and internal features within concrete slabs, columns, and walls. This method facilitates a comprehensive understanding of the underlying structure, which is essential for effective construction and repair work.

Benefits of Ground Penetrating Radar in Concrete and Rebar Detection
Non-invasive and non-destructive: GPR scanning enables accurate mapping of rebar and other embedded objects without damaging the concrete structure, making it a safe and economical choice.
Real-time results: GPR surveys provide immediate feedback, facilitating quick decision-making on site. This reduces delays and helps improve project schedules.
Comprehensive data: GPR is capable of identifying a variety of embedded objects, including rebar, post-tensioning cables, and even voids within concrete. This extensive data helps prevent costly errors during intrusion operations.
Increased safety: Knowing the exact locations of rebar and other objects ensures that workers can safely drill, cut, or core into concrete, reducing the risk of accidents or injuries.
Cost savings: By identifying potential obstructions before they escalate into problems, GPR surveys help prevent costly project delays and repairs.

Which GPR Tools Do We Use
Ground Penetrating Radar (GPR) for Detailed Rebar Location: GPR stands as the premier technology for professionals in concrete testing. Our team is equipped with state-of-the-art GSSI and Proceq GPR scanners, which ensure the finest detail in identifying the internal layout of reinforcing steel and the positioning of utility lines. This technology is non-radioactive and safe, making it suitable for a wide range of structures. Additionally, our Proceq GPR can create both 2D and 3D visualizations.
Core Meter, Rebar Location and Diameter Testing: The PROCEQ PM8000 Pro Meter acts as a high-quality metal detector that detects electromagnetic signals from rebar located near the surface in concrete structures, including slabs, foundations, beams, girders and columns. Implementing this method can also provide an approximate measurement of rebar diameter, which is beneficial in conjunction with ground penetrating radar scans.
