Ground Penetrating radar
GPR stands for Ground Penetrating Radar. It is a geophysical method that uses radar pulses to image the subsurface. GPR is commonly used for non-destructive testing and subsurface imaging in various applications, including construction, archaeology, geology, and environmental studies.
The basic principle of GPR is that it emits electromagnetic waves into the ground and measures the reflections or echoes that bounce back from subsurface objects or interfaces. The radar waves can penetrate different materials, such as soil, rock, concrete, or asphalt, and reflect off boundaries between different materials or objects.
GPR systems typically consist of a control unit, an antenna, and a display screen. The antenna is the main component that emits and receives the radar waves. The control unit controls the radar signal and processes the received signals to create an image or profile of the subsurface. The display screen shows the real-time data and allows the user to interpret the results.

GPR can provide valuable information about the subsurface, including the depth and location of objects, the thickness of layers, and the presence of voids, cracks, or other anomalies. It can be used to detect and locate PT cables, conduits, rebar, underground utilities, buried structures, archaeological artifacts, geological features, and more.
GPR is a non-destructive testing method, meaning it does not require drilling, excavation, or damage to the surface being investigated. It is a versatile and efficient tool for subsurface imaging and has become an essential technique in many industries.
Why Should You Call for a GPR Investigation Before Cutting?
Starting work on pre-existing concrete structures is difficult to plan, as various materials can be hidden inside any given slab. These obstacles, such as pipes and rebar, must be located before work can start.
Cutting concrete blindly can result in personal injury, or costly damage to the property. To avoid the risk of injury, x-ray machines have traditionally been employed to scan the inside of concrete slabs in order to map its contents. However, this process is slow, clunky and potentially unsafe due to the radiation the x-ray machine generates. A far better alternative is the “GPR” system like the one used by Cobra Concrete, the premiere Chicago concrete scanning service.
Overall, using GPR before cutting concrete is essential for ensuring safety, minimizing costs, improving efficiency, maintaining accuracy, and complying with regulations. It is a proactive measure that helps prevent accidents, damages, and disruptions during construction or renovation projects.
A Ground Penetrating Radar (GPR) survey is conducted using the following steps:
It is important to note that conducting a GPR survey requires expertise in data interpretation and knowledge of the subsurface conditions. Professional geophysicists or surveyors are typically involved in performing and analyzing GPR surveys.
