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.
