Page 11: Measurement Principle
GPR is the acronym for Ground Penetrating Radar, also known as Georadar, Ground Penetration Radar, or Ground Probing Radar. Proceq GPR is a compact device that scans the subsurface in a non-destructive way. It can penetrate the surface, based on concrete conditions and antenna characteristics.

Superline scan (see section 5.3). It is equipped with a LED to facilitate data visualization on the iPad display when the user wishes to focus on one line scan view. Figure 12: GP8100 array - 6 lines scan 3. June 2024 © Copyright 2024, PROCEQ SA...
Page 17: Software Overview
When the antenna moves, multiple A-scans are collected along the scan to produce a B-scan radargram view. The colorful migrated view is a more intuitive way view to identify objects; it is produced from a processing radargram. Figure 13 : A-scan, B-scan & migrated views principles 3.

(90° rotation as per Figure 17) and the encoder wheel mounting (see Figure 11). The cross-polarized line scan may unveil the presence of deeper/hidden objects. Figure 17: GP8800 Cross polarization setting 3. June 2024 © Copyright 2024, PROCEQ SA...
Page 20: Superline Scan (Gp8100)
An area scan, also called C-scan, can be generated from the combination of different line scans in each direction (X & Y) as described in Figure 19. Figure 19: Area scan, 3D view & time slice view principle 3. June 2024 © Copyright 2024, PROCEQ SA...
Page 21: Time Slice View
GP app software produces a 3D view improving the level of comprehension for locating targets. The user can adjust the color for each depth intervals differentiating objects by moving the left slider. Figure 21: GP app software 3D view 3. June 2024 © Copyright 2024, PROCEQ SA...
Page 22: Augmented Reality (Ar)
The Tag menu on the right enables the user to tag identified targets such as rebar, live wire, void, backwall or defined objects (like post-tension ducts). GP8000 & GP8100 provide live wire detection (on top of the screen) based on signal strength color intensity that can be adjusted in image processing settings.

“Auto-Gain” which automatically adjusts the gain and amplifies the signal to improve the image quality. However, it is possible to adjust manually the gain with “Linear Gain” & “Time Gain Compensation” settings. 3. June 2024 © Copyright 2024, PROCEQ SA...

Figure 26: Noise affecting GPR object detection GP app software provides in image processing dropdown menu: the “Noise Cancellation” setting which, when activated, noise cancellation removes noise and improves data clarity (Figure 27). 3. June 2024 © Copyright 2024, PROCEQ SA...
Page 25: Background Removal
GP app software provides in image processing dropdown menu: the “Background Removal” setting which, when activated, removes the background, and makes shallow objects easier to see such as rebar as shown in Figure 29. 3. June 2024 © Copyright 2024, PROCEQ SA...
Page 26: Dielectric Constant
When concrete is wet ( 9), GPR waves are heavily attenuated by the presence of water resulting in less prominent signals/hyperbolas. ε) The standard concrete usually has a dielectric ( between 6.5 and 7.5. 3. June 2024 © Copyright 2024, PROCEQ SA...
Page 27 (B-scan) as shown in Figure 32. Make sure the yellow hyperbola precisely covers-up the object’s hyperbola. Try with different clean hyperbolas to confirm the concrete dielectric estimation. 3. June 2024 © Copyright 2024, PROCEQ SA...

Page 29: Adjustable Time Window (Gp8000)
Figure 34: Time window principle GP app software (only with GP8000) provides in the image processing dropdown menu: the “depth/time window” setting. By adjusting the time window from 10 ns (shallow) to 24 ns (deep), the user can either focus on shallow objects or extend the depth to the maximum (150cm / 60in penetration depth for standard concrete).

Measurement Mode: Line scan with tags, perpendicular to beams The raw data view shows top rebar and the PT beam bearing the slab. Figure 42: GP app software raw data view concrete slab with PT beam application 3. June 2024 © Copyright 2024, PROCEQ SA...
Page 35: Hollow Core Concrete Slab
Corroded rebar dissipates GPR waves and returns less energy than healthy steel rebar. Proceq GPR helps to find out the potential presence of corroded rebar, however it is strongly recommended to use other tools & sensors such as GPR Insights post processing software or half-cell potential technology (Profometer PM8500) to strengthen the analysis.
Page 36: Post-Tensioned Concrete Slab
The time slice view reveals at a certain depth all the PT duct layout and few rebar. The B-scan and superline scan in split view confirm the presence of the PT ducts underneath the rebar. 3. June 2024 © Copyright 2024, PROCEQ SA...
