Ground-penetrating radar is equipment designed to analyze electromagnetic contrasts in the soil. It curbs a transmitting antenna and a receiving antenna that allows it to send and analyze electromagnetic waves at a certain frequency.
Furthermore, GPR scanning is a real-time technique that uses high-frequency radio waves. Plus, it helps yield data with quite high resolution in a short time. GPR provides a non-destructive and non-intrusive method of analyzing the sub-surface of the structure. This technique is considered useful when it comes down to conducting due diligence on several materials.
Let us look at how GPR for concrete scanning works.
How Does GPR Work?
The transmitter of GPR pours out a pulse of electromagnetic energy into the subsurface. Subtle dynamics in the subsurface are analyzed based on the changes and variances in the permittivities. When a change in the sub-surface is analyzed, some of the electromagnetic energy is given back to the surface. The detecting antenna conducts this analysis. Also, the variations in the return signal are documented. Finally, the information or data collected from this is put out on a radargram. Not to overlook the ideology that GPR scanning can analyze the changes in the sub-surface. But yet again, it does not tend to determine its exact nature. This is how the concept of ground penetrating radar works. Now, let us look at the things and materials that this radar can detect.What Can Ground-Penetrating Radar Detect?
One can use the technology of ground-penetrating radar to detect the presence and differentiate between metallic and non-metallic material. This technology works in the best ways when there is a huge difference between the electromagnetic properties of the materials that are being analyzed. For the same reason, metallic objects make ideal targets for this technology. Some of the common material targets include, - Metal, - Plastic, - Concrete, - Air pockets, - Dynamics in ground strata. Another important thing that you need to understand is that GPR for concrete scanning will not work in certain conditions like heavy clay soils, especially if they are clogged with water. However, deionized water will not be a problem for ground-penetrating radar. Furthermore, if the water has a high level of minerals present in it, it reduces the signal, making it an unsuitable medium. On the other hand, if we talk about very dense materials, the concept of ground-penetrating radar can easily get across these.What Are the Advantages of Using GPR?
