Ground Penetrating Radar (GPR)
Ground penetrating radar, or GPR, is another locating method that provides underground imagery of the pipes and utility lines by using high-frequency radio waves, similar to that of standard radio wave detection. This technique helps us understand the depth of the utility and pipelines, while the others are merely meant to locate them. Ground penetrating radar is often the second step of the radio wave detection method because we find the radio waves to provide the most insight into your buried pipes and utility lines.
Perhaps the most appreciated trait of the ground penetrating radar system is that it can offer imagery details that other locating methods cannot. Because the high-frequency radio waves work in conjunction to produce a high-quality image of the pipes, the operator aboveground can closely see the details of how the pipes are situated beneath the ground. This method of locating works great for both metal and plastic pipes, as the imagery for both can be displayed, which allows the receiver to see how and where the pipes are lodged.
Depth of Pipes
Another major benefit of the ground penetrating radar locating method is that the images can detect how deep the pipes are integrated into the ground. This allows us some wiggle room when it comes to digging and navigating how the pipes are embedded and where exactly they're located. Not all locating methods can detect how deep the pipes are in bedded into the ground, which is what makes the ground penetrating radar so innovative and preferred amongst our team of professional locators.
Metal and Non-metal Pipes
As we mentioned before, the ground penetrating radar is extremely useful in helping navigate a variety of buried pipes. Regardless of the pipes are made of metal, nonmetal, or entirely of plastic, the ground penetrating radar can take quick images of the pipes and produce them back to the operator that is above ground. This method of locating is extremely useful for the pipes that were installed previously or if the homeowner is unaware of any existing pipes in the area or lacks information.
Voids, Gaps, and Holes
Lastly, the major benefit that ground penetrating radar can offer which all of the other locating methods cannot, is that it can generate and map the subsurface of areas where there are large holes, voids, and land pits. This cannot be done with other methods if you want to achieve accurate results. However, the ground penetrating radar system is easily able to map where holes and deep gaps are in the land, as well as catch any boulders, old or deteriorating foundations, and other potential dangers that lie beneath the surface and can get buried over time. This is extremely useful if you are attempting to rebuild a new structure on an old piece of land that once housed something else, such as a former residence. You’ll want to be sure the foundation was removed completely and a ground penetrating radar can easily do that.
