FAQ

What is GPR?
GPR is a compact device that scans the subsurface in a non-destructive way. It can penetrate the surface from a few cm down to tens or hundreds of meters, based on soil conditions and antenna characteristics.

What are the types of NDT?
Many different NDT methods are available in the industry, each of them having its own advantages and limitations, but six of them are most frequently used: ultrasonic testing (UT), radiographic testing (RT), electromagnetic testing (ET), magnetic particle testing (MT), liquid penetrant testing (PT) and visual testing (VT). Other techniques include acoustic emission testing (AE), guided wave testing (GW), laser testing methods (LM), acoustic resonance testing (ART), leak testing (LT), magnetic flux leakage (MFL), vibration analysis (VA), and infrared testing (IR).

What is SEGY format?
The SEGY (sometimes SEG Y) file format is a commonly used data standard for the exchange of geophysical data. It is mainly used for Seismic data, but also for saving GPR raw data. Our GPR SEGY files can also be used for post-processing data.

What is acquisition time?
Time in GPR has different meanings: Time Window = the maximum recording time shown on the data. This can be used to calculate the depth. Acquisition Time = how long it takes to finish one A-scan measurement with a perfect electronics instrument for pulsed GPR. However, GPR devices are not able to collect one A-scan in a single pass and, to reduce noise, normally an A-scan is measured multiple times, and then results are averaged together. So the Acquisition Time is longer than the Time Window. 

What is Stepped Frequency Continuous Wave?
Unlike Pulsed-GPR broadcasting a signal centered around one frequency, resulting in a trade-off of resolution and depth for inspecting, stepped frequency continuous wave (SFCW) has the advantage to broadcast an ultra wide-band range of modulated frequencies. The combination of all frequency response enables detection of objects from shallow to deep depth in one scan.

What does GPR stand for?
GPR is the acronym for Ground Penetrating Radar, also known as Georadar, Ground Penetration Radar, or Ground Probing Radar.

How does GPR work?
GPR emits electromagnetic (EM) waves to the subsurface and calculates the time these waves need to travel through the various subsurface material and get back to the GPR receiver. This two-way travel-time, along with a few other parameters such as the dielectric, provide the user an estimate of the target depth.

What applications does GPR cover?
GPR is a very useful tool in a variety of applications. Most popular uses of GPR are the non-destructive testing and mapping of objects inside the concrete, such as rebars, pipes, ducts, and cables. Other applications are infrastructure assessment (bridge decks, roads), utility location, archaeology, forensics, environmental studies (mapping contaminants), shallow geology and geophysics, mine exploration and safety, transportation (pavement thickness and density, ballast fouling), agriculture, military (UXO), sedimentology, glaciology, quarrying, space exploration.

Will my GPR work as standalone unit or can it also complement other methods?
Both. GPR can be used as a standalone unit if you work on specific applications and you are happy with a limited set of feedback and information. However, it is not a tool for every job you may have onsite. In concrete applications, GPR can be used in combination with Ultrasound Tomography (Pundit Array: https://bit.ly/3cBBeTE) and Eddy Current Rebar locators (Profometer: https://bit.ly/39B0QhJ) to get a comprehensive approach.

How deep can GPR penetrate the concrete?
This depends on how young the concrete is; young concrete is not well cured, has more water and thus the radar does not penetrate that deep. Older concrete is usually drier and thus better for GPR.

What is the most used data format for GPR?
Typically, GPR exports data in the SEG-Y format. This can be easily converted to other formats like .xls, .dxf or .kml if needed for further visualization of data.

Is Screening Eagle GPR certified?
Yes. Our equipment meets CE, IC, FCC, ETSI-EN RSS-220 and RoHS regulations.

Do I need to calibrate my GP8x00?
No. GPR self-calibrates each time you turn it on. There is no need to send your unit back to a repair/calibration center.

Does GP8x00 work on all surfaces?
GP8x00 has wheels and a certain clearance from the surface. If the wheels can move over the surface the GPR can collect data. Moving over conductive materials, e.g., aluminum, copper etc. can limit or even zero the depth penetration of your antenna.

Will my GP8x00 GPR collect any data if I do not move?
No. Data collection on GPR systems (GPx and GSx) is triggered by wheel movement. If you do not move the radar, then no data collection is happening. The wheel is acting also as an odometer, giving local coordinates on the x-axis direction.

Does GPR calculate the diameter of a rebar?
GPR is not the ideal tool to calculate the rebar size. There is a technique where you can get approximate values for the rebar size by measuring the depth to the rebar from both in line and cross line data and the difference will give an approximate diameter. There are more accurate and easier instruments to detect the rebar size and cover (Profometer: https://bit.ly/39B0QhJ) which can be used in combination with GPR for a holistic approach to your concrete investigations.

I have a rebar locator, why should I buy a GPR?
Rebar locators (Profometer: https://bit.ly/39B0QhJ) are the most economical and accurate solutions to map the first layer of rebars in concrete. They accurately measure the rebar cover independently of concrete properties (dielectric). GPR can detect metallic and non-metallic targets that are deeper inside the concrete and can also detect larger voids inside the concrete, plastic conduits, and other non-metallic targets, as well as find the slab thickness and concrete bottom. If you already have a rebar locator, adding a GPR will give you complementary capabilities to deliver best in class results to your customers.

Can I detect voids and delamination using GPR?
Air inside the concrete results in a partial reflection of the GPR signal, which allows you to detect larger voids. Thin delamination and small voids only give a small reflection and can typically be visualized using GPR. Contrary to GPR, Ultrasound tomography (Pundit Array: https://bit.ly/3cBBeTE) results in a full reflection when interfacing air. This makes Ultrasound the ideal solution for investigation delaminations and small voids.
