This GPR scan took place on the edge of an elevated concrete slab on the exterior of a commercial building in Dallas, TX. The customer needed to identify the locations of the post tensioned cables running through the slab so they could safely install anchors for new glazing. Concrete reinforced with post tensioned (PT) cables can cause serious injury or damage if the cables fail as a result of being struck. The PT cables needed to be clearly marked before the customer commenced destruction of the reinforced concrete slab.
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 cables and the client was then able to safely and effectively drill for the anchors.
GPRS, Inc. can identify structural steel embedded in the concrete with an accuracy of (+/-) ¼”. This is important to note because there are often times when a customer has to drill in a specific location to install conduits or plumbing on refits of existing structures. The obvious benefit of having such a high degree of accuracy is we can determine the best place to drill in a highly congested area.
