Digital concrete rebar scanning is the process of finding subsurface hazards through GPR (Ground Penetrating Radar). Objects such as pipes, conduits, post tension cables and utilities are detected by this technology. Unlike X-ray imaging, which requires special precautions, and emits harmful radiation to technicians and the people in the area, GPR is non-intrusive, safe and produces immediate results.
Cost-Effectiveness
Using concrete scanners to locate embedded reinforcement can save a contractor time, money and prevent damage. Typical examples of this include steel rebar, post-tension cables and conduits. Disturbing these inclusions can have a negative impact on the strength and performance of the concrete, leading to millions of dollars in repairs.
Digital Concrete Rebar Scanning is cost-effective because it requires less equipment and personnel than other methods of locating embedded items. Additionally, it is faster and easier to process. It can also save time and money in rebar and conduit removal, making it an excellent choice for projects with large-scale scopes.
Ground penetrating radar (GPR) is used to scan embedded structural reinforcement in concrete, including rebar patterns, post-tension cables and pipes. It also can detect voids and corrosion within the concrete to help avoid major structural damage.
Accuracy
Digital Concrete Rebar Scanning is an accurate and reliable method of locating reinforcement in concrete. It is a fast, safe and cost-effective way to ensure that all changes to a structure are done properly.
The accuracy of the rebar location process depends on a number of factors, including the depth and spacing of rebars toward the direction of scanning, the type of reinforcement, and the quality of the concrete surface. It is also affected by spectral analysis and compensation procedures of systematic measuring errors.
Tests on specimens with rebars of 16 and 20 mm diameter, spaced at more than 20 mm, indicated more significant inaccuracies in measurements than tests on rebars with diameters of 10 mm. However, the measured diameters and cover were still very accurate.
Safety
Digital Concrete Rebar Scanning is a non-destructive concrete inspection process that can find and locate conduit, pipe, rebar, post tension cables and voids inside concrete structures. It uses radar technology to “see into” the surface of the concrete to identify obstacles and voids, without damaging any surrounding structures or reinforcing steel within the concrete.
Performing a scan before cutting, drilling or core drilling into concrete can save you time, money, and keep workers safe. It will also prevent costly mistakes and ensure safety measures are taken to avoid damage to concrete reinforcement, utility lines, and piping.
The most common reason for conducting a concrete scan is to locate and find rebar, reinforcing steel that is embedded in concrete slabs and foundations. It can help you determine the proper rebar spacing and location before cutting or drilling into the concrete.
Time-Saving
Digital concrete rebar scanning before any cutting or core drilling takes place can save valuable time and money. Having a clear picture of the areas to be cut and/or drilled ensures that no subsurface object will be accidentally hit during construction, demolition, or excavation work.
Whether you’re a homeowner or a contractor, scanning a structure before cutting, coring, or digging will help prevent expensive and frustrating delays. By avoiding strikes, you can keep your project on schedule and on budget.
Several methods are available to locate embedded objects within concrete, including ground penetrating radar (GPR), X-ray, and other types of scanning technology. Each method has its benefits and limitations, so it’s important to choose the right one for your project.
