GPR Scanning for Post Tensioned Cables – Dallas, TX

This GPR scan took place on an elevated concrete slab inside a high rise in downtown Dallas, TX. The customer, an electrician, needed to core drill through the slab in order to run new wiring for a refit. The concrete slab was reinforced with post tensioned (PT) cables, which can cause serious injury if struck in the event of a failure. The PT cables needed to be clearly marked before the electrician could begin drilling.

David Hagenmayer with Ground Penetrating Radar Systems, Inc., was contracted to scan the area requested and mark out all PT cables and obstructions in the concrete. David was able to determine the precise locations of the existing lines. The client was then able to safely and effectively drill.
