Bridge Deck Monitoring

Regular inspection for condition assessment and monitoring of concrete bridge decks is of paramount importance for predictive maintenance of these infrastructures. Deterioration of steel-reinforced concrete structures is complex and can be caused by the corrosion of embedded reinforcement, decomposition of concrete, or both. Among other technologies, GPR has been increasingly used for monitoring the deterioration at the top layer of reinforcing.

GPR Insights uses AI to automatically detect top reinforcing steel in concrete GPR data sets. The Analytics menu provides a straightforward workflow to generate qualitative maps of top steel from the AI-detected points:

  1. Likelihood of deterioration maps (following the ASTM D6087 standard),
  2. Velocity/dielectric maps (Relative changes on those parameters are likely related to moisture content at or above the first rebar layer across the deck) and
  3. Concrete cover maps.

Utility Mapping

For the last three decades GPR has been increasingly used as part of an arsenal of tools to map buried utilities. Although the latest multichannel GPR (MCGPR) systems provide very high-resolution images in real-time, different workflows and methodologies are still applied. Software can play a big role in boosting digital mapping and making it scalable. Therefore, GPR measurements are often post-processed and analysed for the presence of utility like features which are then interpreted and exported to maps.

GPR Insights has been designed to streamline this process providing:

  • The fastest data processing from raw to 3D imaging
  • Virtually unlimited amount of data (project size)
  • Dedicated interface with interconnected data views including: A-scan, B-scan, Slice, C-scan and T-scan
  • Import of as-built maps to compare with GPR slices
  • Drawing tools, customized utility library tags and POIs for interpretation
  • 3D material textures (Metal, plastic, concrete and brick)
  • Export to AutoCAD®, Google Earth™, ArcGIS or CloudCompare.

These capabilities make GPR Insights the fastest and most effective software for utility mapping allowing you to cover thousands of square meters in a single day.
