GPR, or ground penetrating radar, is a useful tactic that helps identify issues beneath the surface of the ground before they become destructive or even catastrophic events. Continue reading to learn more about the benefits of GPR for sinkhole and void detection.
How Sinkholes and Voids Develop
Sinkholes and voids can develop almost anywhere, as they only require the right combination of subsurface materials that shift and deflate. Soft soil and karst limestone are two main culprits of sinkholes. Human activity has also been known to cause sinkholes and voids, especially from mining and leaking or burst water pipes.
GPR is the most reliable method for detecting issues beneath the surface of the ground. It also releases a weaker signal than a cell phone, making it a safe technology to use. Industry professionals use these devices for sinkhole and void detection but also to prevent disasters that could cause expensive destruction to property and potential injuries to people.
The main benefit of using GPR technology for sinkhole and void detection is the high-quality imaging achievable with this technology. It works for both surface and subsurface materials by providing two-dimensional images that reveal a cross-section of the area. These images allow for accurate and reliable diagnoses of potential soil issues. Industry professionals will use those images to suggest repairs and other measures that need to be taken to ensure that the area will remain safe and structurally sound.
GPR technology uses signals that bounce off structures like voids. Those signals will then send echoes back to the GPR equipment, which is translated into data by the trained technicians. The signals are harmless yet efficient for detecting voids through a great variety of natural materials, including soil, sand, silt, gravel, granite, limestone, shale, clay, wood, and other plant and man-made materials.
In some cases, GPR technology by itself is not enough. The electromagnetic waves can sometimes be absorbed by certain subsurface materials. In those cases, the trained technicians can use the GPR technology in conjunction with other methods to gain a better understanding of what’s happening beneath the surface.
