GPR Scanning or Ground Penetrating Radar scanning is a non-destructive, industrial standard, surface method of accurately inspecting concrete structures. It is used to measure slab thickness, locate rebars, PT cables, conduits, and voids, and inspect the concrete structure.

The purpose of GPR for concrete scanning is to avoid accidents in concrete drilling by revealing the exact location of the utilities and evaluating the structure. Have a look at why using GPR for concrete scanning over X-ray scanning or other non-destructive concrete scanning methods is a good idea.

Reliable Results

GPR scanning produces accurate and reliable results. It uses electromagnetic waves to inspect the structure. In this method, a transmitter is used to transmit the electromagnetic waves to the concrete structure that reflects back when they hit the obstacles. The reflected waves are received by the receiver antenna. A testing engineer analyzes the images produced by the change in the frequency to identify the exact location of the utility. The result shown by the GPR may not be reliable in some situations, but most of the time, you can easily locate metal, plastic, utility lines and pipes, voids, conduits, and other materials.


GPR scanning is highly cost-efficient. It produces quick results. The GPR radar provides the quick results that a testing engineer can analyze on the site to locate the utilities. It is very important to note that this method of concrete scanning is not all about the GPR. The reflected waves do not reveal the type and location of the utility. It is the GPR engineer who analyzes the images to mark the location of the utility.

Quick Results

GPR scanning is a quick method of concrete scanning. GPR of concrete scanning does not require preparing X-ray films offsite in the labs. Although the quality of the scan produced by the X-ray scanning is good, in most cases, GPR scanning fits the purpose. It takes less time to inspect the concrete structure, which is vital when working on commercial buildings.

Ease of the Use

GPR scanning can be used to inspect almost any concrete structure. It does not require access to both sides of the concrete structure. Also, as it uses the electromagnetic waves of low frequency, it does not cause the trouble of restricting the area to be scanned like X-ray scanning. You can inspect various structural elements such as slabs, columns, beams, asphalt surfaces, and much more conveniently.

These are the key reasons why GPR for concrete scanning is a good idea. If you are looking for an answer to the search query ‘GPR scanning near me,’ you can get in touch with Concrete Insight to use our professional concrete scanning services.
