Do you want an accurate and non-invasive solution to identify the buried assets on a construction site? Ground-penetrating radar or GPR scanning is a cost-effective and time-efficient solution. It provides high-resolution data and locates both metallic and non-metallic utilities. Therefore, hiring the GPR services before starting any groundwork is a wise decision.

The GPR scanning reveals the exact location of the utility and minimizes the risk of damaging PT cables and electric wires. In addition, when GPR scanning is used before the concrete coring, it also helps avoid the cost associated with the repair, lost time, injuries, and related expenses. So, read this post to know how the GPR system helps inspect concrete structures.

How GPR Scanning Works?
Ground Penetrating Radar is a compact and non-destructive device that scans the subsurface. It penetrates the surface from a few centimeters down to tens or hundreds of meters based on the surface condition and device characteristics. For inspecting the concrete structures, antennas in the range of GHz are used for better horizontal resolution.

The GPR or ground penetrating radar system sends an electromagnetic pulse of energy into the structure. The pulse wave velocity changes when a pulse passes from one material type to another. The shift in the wave velocity causes energy to be reflected back to the receiver and provides a record.

There are two different types of GPR devices – the pulsed systems and the stepped frequency GPR. The pulsed system sends tiny pulses of EM waves during periodic intervals. On the other hand, the stepped frequency device sends parcels of waves continuously at different frequencies at the same time.

One of the popular and effective ground penetrating radar systems for concrete scanning is GSSI Structure Scan Pro SIR400. It can accurately detect metal, plastic, PVC, concrete, natural material, air pockets, and geological features.

Ground Penetrating Radar FAQs 

What is Ground Penetrating Radar?
GPR is also known as ground radar, subsurface scanning, georadar, or ground probing radar. It is a technology that uses radar pulses to create images underground.

Can GPR be used in water, snow, or ice?
Yes, it can be used in freshwater and snow. However, a high level of moisture can have a negative impact on the ability to provide accurate data.

Is it safe to use GPR?
Yes, the GPR technology is safe to use. It may sound dangerous and complicated, but you can hire GPR professional services for safe and efficient operations.

Can GPR locate other underground objects?
GPR scan subsurface anomalies (abnormal areas) in a specific area. It could be anything from unknown graves to tunnels or buried tanks.
