Ground-Penetrating Radar (GPR) and Concrete Scanning (X-Ray)
Every time, when you need to locate what is in the concrete without demolishing it, you have two main options to choose from. The most popular techniques are ground penetrating radar GPR and concrete scanning X-Rays. As such, both have their advantages, according to your specific needs. When planning renovation or repairs, so you need to trace rebar or post-tension cables, you could use X-rays. Coring or cutting through concrete floors, walls or locating lines may lead to its own set of complications. X-rays are categorized as a carcinogen by the International World Health Organization and this technique greatly increases the need of evacuation of the entire area. There is also a personal protection for anyone working there to keep the technicians safe while they are in the working site.
If you opt for a more efficient, quick and completely safe process you can implement ground penetrating radar so you can easily detect post-tension cables, pipelines and other items in concrete walls or floors. A GPR image can adjusted for structure inspection of bridges, towers, tunnels and other surfaces when the concrete thickness is not greater than 18 inches. GPR equipment can be employed for mapping and locating items in concrete and also creating detailed reports that can point and easily identify anomalies and depths as well.
The advantage that x-rays have over GPR comes along with the computed tomography, fluoroscopy and even radiotherapy. If you compare the images after both technologies you can easily notice how x-ray images have higher resolution when it comes to identifying smaller wall structures.
The other comparative difference when choosing between these two technologies is the price as a huge and determining factor. GPR is significantly less expensive over concrete x-ray imaging. The latest technological improvements of GPR software allow easier processing and manipulation, so GPR becomes a preferred choice in almost every situation over x-ray imaging. GPR technology can assist in many locations except in high moisture conditions as they will reduce its performance.
So if you have a project that needs cutting, drilling or coring you may get benefited by the application of x-ray scanning or GPR inspecting as it helps to achieve clearance for the project. Concrete investigation allows penetrations deep into the structures so clients can have a peace of mind knowing the most accurate findings and their interpretations.
