Ground Penetrating Radar (GPR)

We understand the importance of quality control testing for the planning phase and construction process.

Reaching depths of up to 20 inches, our non-intrusive Ground Penetrating Radar (GPR) system for concrete scanning allows us the ability to locate rebar, conduits, post-tension cables and voids.  STL also has the capability to determine concrete slab thickness in real-time.  We can operate in 2D mode for real-time locating, and 3D mode for x-ray like images of the concrete. This system also incorporates two types of automatic target detection which enables us to interpret and report data accurately.  By using an integrated laser positioning system, we are able to accurately mark targets which helps us to ensure efficient and accurate data collection.

Our GPR Inspection services allow us to:

• Locate metallic and non-metallic targets in walls
• Inspect bridges, monuments, walls, towers, tunnels, balconies, garages and decks
• Map relative concrete condition for rehab planning
• Measure slab thickness
• Void location
