Concrete Scanners

Concrete Scanning for Non-destructive Concrete Investigations.

 

Our team use a variety of tools to further investigate the void, depth, utilities and reinforcements of any concrete surface. For example, the Ground Penetrating Radar (GPR) can be used to accurately locate steel reinforcement. GPR is a rapid, cost-effective and 100% non-intrusive method. GPR can help inspectors and engineers verify the as-built reinforcement, identify top and bottom rebar locations (i.e. in slabs, and walls), and find the configuration of transverse reinforcement. For example, if structural engineers need to verify the spacing of the reinforcement in the potential plastic hinging zone, GPR can help verify the spacing of the stirrups. GPR can also be used to identify the amount of concrete cover over the reinforcement. Additionally, the use of a Ferroscanner Cover Meter verifies concrete cover and identifies ties in brick walls.

Another important group of tests are ultrasonic testing of concrete. Ultrasonic methods, such as Ultrasonic Pulse Echo can be used to predict the thickness of concrete elements with one-side access. Ultrasonic Pulse Echo can also be used for determination of grout fill of Drossbachs, ReidBar Grout Sleeves and Post-tension (PT) Ducts. The Ultrasonic Device and GPR can be used to identify voids in concrete. The 900Mhz GSSI antenna/scanner has capability to scan for large voids and reinforcement up to 1m depth.

The GSSI Bridge Scan Radar is useful for detecting deterioration of reinforcement in bridge and wharf decks over large areas. The Bridge Scan Radar can produce a cover survey of reinforcement for Quality Assurance.
