Understanding Ground Penetrating Radar Brisbane Ground penetrating radar is a non-destructive method for discovering what lies beneath the ground. It's a practical option with numerous advantages. Ground penetrating radar is a non-destructive method for discovering what lies beneath. This technology has a wide range of applications and benefits, including mapping underground space and detecting buried objects. The technology can also be used to test for underground pipes and cables and to measure the permeability of soil layers.
What is GPR? Ground Penetrating Radar (GPR) is a radio-wave-based method of investigating subsurface structures. It has the ability to see through the ground and into the earth, making it useful for detecting buried objects. It operates by bouncing pulsed signals off the earth's surface and measuring the time it takes for them to return from depth. The greater the amount of metal between you and your signal, the longer it takes for that signal to return up through your tools, personnel, and so on. As a result, if you're looking at an area with little metal (such as a building), your measurements will be more accurate than if there's a lot of metal present, because all those waves will bounce right back at each other. Because their length limits were exceeded during travel time calculations, they will be less accurate overall. This could lead to false positives, where we think we found something when there was nothing there. Why is ground penetrating radar important?
