Penhall marks the rebar found after performing scanning

Scanning with ground penetrating radar to avoid hitting cablesPenhall performed a scan using ground penetrating radar on 6″ thick post tension slab prior to coring to avoid any cables or other structural wires in the slab at a project in Atlanta, GA.

Concrete Scanning used to check for obstructions in concrete

Concrete scanning to check for obstructionsIn Marietta, GA, we were asked to check for obstructions, such as rebar, conduit and utilities, before core drilling a 4″ hole on a 6″ tick concrete slab.

We make sure we have all the tools and antennas to ensure the most accurate concrete scan

best equipment for concrete scanningPenhall traveled north from the Atlanta office to Euharlee, GA to examine a 6′ x6′ area on a 6″ thick elevated concrete slab. We were able to find and mark rebar and post tension cables to avoid when cutting.

Ground penetrating radar is used by our expert analysts to detect hazards before cutting or drilling

At a project in Alpharetta, GA, we were asked to scan 29 separate locations prior to drilling cores of sizes ranging from 2″ – 6″ on a 5″ thick concrete slab. We were able to avoid any hazards when finally administering the drilling.

Protect against cutting rebar or conduit when performing core drilling

concrete scanning in atlanta gaPenhall Technologies completed a project for a general contractor at The Battery outside the new Atlanta Braves, Suntrust Park. The contractor needed to protect against cutting rebar or conduit when performing a core drill. Ground penetrating radar was used to locate the rebar. This was the perfect method for a slab on grade project, as it only requires access to one side of the concrete. To locate live conduits, a utility wand was used to sweep each area for power and communication lines. Our GPR Analyst was able to provide quick and reliable results, which allowed the project to stay on time and on budget.
