If there is a need for you to find out what is located within concrete, but you do not wish to demolish it, then there are two main options that you can choose between. The number one option that you have is that of using concrete scanning X-rays, while the second option is that of using ground penetrating radar or GPR. On the whole, both of these techniques serve the same purpose, and there are advantages and disadvantages of both.
When planning out renovations, it is necessary for you to have post tension cables traced out. In such a case, it might not be possible for you to use X-rays considering that these are carcinogens and the utilization of this technique might even deem it necessary for you to get the entire area evacuated. You will also need to take steps to ensure the overall safety and protection of the technicians as they work on site. In such a case, the best thing for you to do is to opt for GPR concrete scanning. The technique is not just efficient but quick and safe as well. By using it, you can easily detect pipelines, post tension cables and a number of other items in floors and concrete walls. It is also possible for GPR images to be adjusted so that a more so structure inspection can be conducted over towers, bridges and tunnels that have a concrete thickness of less than 18 inches. Items in concrete can also be located and mapped using GPR equipment. Apart from that the same can be used for the identification of anomalies in concrete.
If truth be told, X-rays do have certain advantages over GPR. The fact of the matter is that X-rays offer computed fluoroscopy, tomography and radiotherapy. What this means is that when images acquired by both these techniques are compared, you will find that those acquired through X-rays have higher resolution, which is why this technique is best used for the identification of smaller wall structures but when it comes to cost GPR is comparatively less expensive. Apart from that GPR software is much easier to process and manipulate which is why it is largely preferred over X-ray imaging. However, what you need to bear in mind is the fact that GPR technology does not have the potential to be used in high moisture conditions for the simple reason that it will cut down on its ability to perform.
