Why is Ground Penetrating Radar Preferred Over X-Ray for Concrete Scanning?
Concrete scanning is the process of inspecting the concrete structure to locate the subsurface features. It is used to locate the utilities, detect air voids, and calculate rebars spacing and location. The two most common methods used for concrete scanning are GPR scanning and X-ray scanning. GPR scanning is used as the industrial standard. Contractors hire concrete scanning services for finishing work and structural maintenance projects. Here are the three reasons to prefer GPR over X-Ray scanning: 1. Accurate and Quick Results Concrete Scanning with GPR produces immediate and accurate results. Electromagnetic waves are used to inspect the concrete structure that can accurately tell the location of subsurface features. 2. Safe GPR scanning uses electromagnetic waves in safe wavelengths, whereas X-ray scanning utilizes waves in harmful wavelengths that require halting of the operations on the site. GPR scanning can be used anywhere without restricting the work. 3. Cost-effective GPR scanning is a cost-effective method of concrete scanning. It does not require setting up X-ray films on both sides and processing the images off-site in the lab. It inspects concrete surfaces in a cost-effective manner as it does not have special requirements.
