The majority of the residential and commercial structures are made of concrete. Concrete is an exceptional building material, but the only problem with concrete is that it is not transparent. You cannot just tell what is beneath the surface just by looking at it. That’s where the role of concrete scanning techniques like Ground Penetrating Radar scanning and X-Ray scanning comes into play.


There are many techniques to inspect and scan a concrete structure, but GPR Scanning is most commonly used. In this post, we will look at why GPR is most commonly used for inspection of the concrete structure and locating utilities.

Accurate and Reliable Results

The major reason why most finishing-work contractors prefer GPR scanning is because it produces accurate and reliable results. GPR scanning uses electromagnetic waves to map the structure. A transmitter is used to transmit the electromagnetic waves to the concrete structure that reflects back when they hit the utilities. The reflected waves are received by the receiver antenna. A testing engineer analyzes the images produced by the waves to identify where the utilities are located in the concrete structure. This method can locate metal, plastic, utility lines and pipes, voids, obstructions, and conduits.

Can Scan Any Structure

Concrete scanning with GPR can be used to inspect any concrete structure. There are no requirements like access to both sides of the concrete structure or restricting the entire area, as in the case of X-ray scanning. You can inspect almost any concrete structure. It is a versatile method that can scan slabs, columns, beams, asphalt surfaces, and much more.


Cost-Efficient and Take Less Time

This method produces quick results. Your testing engineer can analyze the graphs on-the-site to locate the utilities. There is no need to prepare the film offsite to produce images. This reduces the overall time it takes to inspect the concrete structure. Not just this method takes less time but cost-efficient also. No significant skilled labor is required to perform the concrete inspection. Advanced ground-penetrating radars offer reliable scanning at affordable prices.

Safe Method

GPR scanning is a pretty safe method for locating utilities. It does not use harmful waves to locate utilities. This makes the method safe for other workers working on the same project. Not just that, it also eliminates the need to restrict the area or halt the business operations. You can safely inspect the concrete structures.

These are the key reasons why GPR scanning is used for locating utilities.

If you need to inspect your concrete structure for maintenance work or new utility installation, you can hire expert concrete scanning engineers at Concrete Insight.


We at Concrete Insight use the advanced ground-penetrating radars to accurately inspect concrete and structure, measure slab thickness, and locate rebars, PT cables, conduits, and voids.
