CASE STUDY - Locating Rebar and Post-tension cables
A Ground Penetrating Radar Investigation
Our client was an electrical and plumbing contractor.
Our goal was to investigate 9 proposed core locations and find a window in which 6-inch cores could be cut through the concrete without cutting rebar or the post-tension cables.
This image was of an adjacent pad which illustrates the density of the rebar.
We used our GSSI SIR-10A+ ground penetrating radar unit.
We used both the 900KHz and 500MHz antennas to check the 9 proposed core locations.
These are the marks we placed on the concrete illustrating the rebar and post-tension cables locations.
Our client then assisted in finalizing core locations.
The final core locations were reinvestigated to confirm that absence of rebar and post-tension cables.
They were later successfully cored.
Below is the GPR data over a proposed core location.
