Locating Post Tension cables in Tennessee

Any time a slab with Post-Tension cables needs to be drilled or cut, safety needs to come first. If a Post-Tension cable is hit by a core drill or saw it can cost thousands of dollars to repair and could even injure or kill a worker. Using the latest technology, Ground Penetrating Radar Systems is able to precisely locate PT-cables quickly and safely. Our GPR technicians are thoroughly trained so they understand the types of slabs they are scanning and they are confident with their results.
