Scanning will provide a condition assessment to structural engineers and transportation departments with reliable data that displays areas of deterioration and delamination of bridge decks limiting the need to core. We can also determine the position and depth of rebar and the thickness of the concrete cover.
This use of Ground Penetrating Radar can also provide assessments for aging parking garages, balconies, and suspended slabs.

The StructureScan™ Mini 1600 MHz antenna, survey cart with encoder wheel
Depth penetration of up to 50cm (20 inches)
Geophysical Survey System’s BridgeScan is a convenient cart-based ground penetrating radar system for non- destructive bridge inspection and analysis.
- Significant advantages of using GPR for bridge deck assessment include the non- destructive nature of the technique,
- The ability of GPR to be used without requiring the removal of an existing asphalt over lay
- To provide a quantitative record independent of operator interpretation
- Expediency of job evaluation
The most accurate bridge deck condition assessments using GPR have been performed using high frequency ground-coupled antennas. The high frequency(1.6 GHz) ground-coupled antenna provides excellent resolution of the reinforcing steel.
