Concrete Scanner

Proceq GP8800 Ground Penetrating Radar is an ultra-compact, powerful GPR unit that quickly scans in tight spaces, on curved surfaces, overhead, and close to the walls of concrete bridges, structures, and pavements. This handheld model operates with Stepped Frequency Continuous Wave (SFCW) technology, sweeping through a range of frequencies during scanning instead of the one-channel operation of pulsed-radar units. The 0.4 to 6.0GHz SFCW operation achieves penetration depths of 25.6in (65cm) with high-resolution characterization with a single antenna.

The GP8800 detects reinforcing bars and steel mesh, secondary layers of reinforcement, tendon ducts, cables, conduits, and other embedments. Voids, inclusions, and discontinuities are also identified, and slab or wall thicknesses are measured from a single side. Ground penetrating radar is the ideal technology for structural investigation, as-built verification, rebar detection, and thickness measurement.

The exclusive wireless tracking wheel adjusts between trailing and sidecar configurations for flexibility in cramped environments and to permit cross-polarized scanning. The cross-polarization method combines data from two scans in perpendicular directions from the same area, greatly increasing instrument sensitivity and resolution. For scanning in narrow areas with as little as 2.5in (63mm) of clearance, the battery pack can be removed and tethered to the scan unit with a USB-C cable.

Like other GPR Live models, the GP8800 connects wirelessly over encrypted Wi-Fi to the user’s Apple^® iPad^® with iPadOS 13 or later. Live Pro software uses the powerful post-processing capacity, high visual resolution, and reporting and collaboration features built into the iPad as an ideal platform to view, collect, and distribute results. Visualizations, graphics, and report data can be shared instantly to the cloud from any location.

Data migration processing displays results with realistic 2D and 3D imagery throughout the detection depth. Using Apple’s ARKit^™, augmented reality (AR) images can be overlaid on the real-world environment when viewed through the iPad, providing real-time, in-situ imaging of the subsurface elements. iPad hardware and operating systems can be upgraded at any time for improved performance and new features with no need to replace the GPR sensing unit.

Memory and display capabilities allow straight-line scans up to 3,281ft (1,000m), but the unit is better suited ergonomically for shorter line scans and defined areas up to 47.2x47.2in (120x120cm).

The GP8800 antenna is completely contained within the compact housing. The wireless tracking wheel attaches to any side of the housing to allow scanning in any direction and easy cross-polarized measurements. Powered by four rechargeable flight-safe or readily available alkaline AA batteries, the unit operates for up to 2.5 hours under continuous use.

A tethered after-market 5VDC 2A power bank can also be hot-swapped for the battery pack to extend operating times to 8 hours on large projects. Wi-Fi connection to the iPad allows independent operation with no cables at ranges of up to 65ft (20m). Optional accessories include an extra battery pack with rechargeable AA batteries and an ultralight telescoping alloy rod for hard-to-reach areas.

CT-154R GPR Live Pro includes the GP8800 sensing unit and a two-year subscription to GPR Live Pro software. A Wi-Fi module, USB-C cable, carrying case, wrist loop, battery pack, chalk, and two sizes of grid paper are also included.

CT-156R GPR Live Pro Full Package includes the GP8800 sensing unit and Pro software with a one-year subscription and a telescopic rod with a tablet holder that enables convenient access to hard-to-reach areas. A Wi-Fi module, USB-C cable, carrying case, wrist loop, battery pack, chalk, and two sizes of grid paper are also included.

GPR Live Pro data is tracked and secured in the cloud through the Logbook. In addition, to live data sharing, this allows post-processing and data review from any iPad when signed into the connected account. All measurements, changes, gain, and filter settings are tracked and included with the scan. Geolocation, photos, audio notes, and comments can be added to the scan for quick reporting of details to off-site personnel.

Both CT-154R and CT-156R GPR Live Pro systems require a software subscription for full functionality. The Live Pro Software allows the ability to share images and data with your clients via URL, HTML, etc., 3-dimensional functionality, and augmented reality. A two-year subscription is included with both the CT-154R and CT-156R. Subsequent one-year subscription renewals can be purchased as CTA-59 and are required beginning two years from receiving and activating the GPR system’s original subscription
