GSSI has announced an affordable and flexible ground-penetrating radar (GPR) system ideal for assessing concrete condition on bridge decks, parking structures and balconies. In introducing BridgeScan, the company points out that accurately determining concrete condition improves repair cost estimation, saving time and money.
With BridgeScan, identification of rebar location and depth is easy and quick, making it excellent for bridge deck condition assessments, determining concrete cover depth on new structures and concrete inspection, as well as measuring slab thickness, and void detection and location. Construction professionals, utility locators and engineers can also use the unit as a basis for a utility-locating GPR system to map and locate underground infrastructure, pinpointing the depth and position of metallic and non-metallic pipes in real time.
BridgeScan is tailored for bridge condition assessment, accurately representing bridge data by automatically accommodating for bridge skew angle. Using a non-destructive method of evaluating bridge deck thickness, the BridgeScan system can obtain reliable thickness measurements in minutes, eliminating the need to core.
The BridgeScan system includes the SIR 3000 control unit, a small, lightweight GPR system designed for single-user operation that incorporates advanced signal processing and display capability for “in-the-field” 3D imaging. The same control unit can be used for multiple applications.
Other BridgeScan components include a 1600 MHz antenna, three-wheel survey cart with encoder wheel, and a 2-meter control cable. Also included is a transit case for the control unit, batteries and charger, as well as RADAN software and application-specific software for bridge deck condition assessments. The system’s self-contained cart design and integration with GPS makes it intuitive and easy to use. BridgeScan comes with a two-year warranty.
Geophysical Survey Systems Inc. specializes in the development, manufacture and sale of GPR equipment, primarily for the concrete inspection, utility mapping and locating, road and bridge deck evaluation, geophysics, and archaeology markets. The equipment is used all over the world to explore the subsurface of the earth and to inspect infrastructure systems non-destructively.
