GPRS of Dallas Locates PT Cables and Keeps Project Safe and On Schedule

This GPR scan took place on an elevated concrete slab at the new Toyota Headquarters in Plano, TX. The customer needed to install 150 brackets for reinforcement of the glazing of the building. The concrete slab was reinforced with post tensioned (PT) cables which can cause serious injury or damage if struck during drilling. The PT cables needed to be clearly marked before the customer could drill holes for the anchors.

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.
