Rebar, Post Tension, Conduits? No problem for GPR- Charlotte, North Carolina
Ground Penetrating Radar Solutions - GPRS - of Charlotte, North Carolina was contracted by a general contractor to locate all reinforcement, post tension, and conduits within a concrete slab in order to anchor a trash compactor into the slab. The general contractor needed to avoid all reinforcement as requested by the project engineer. They also wanted to avoid all conduits and post tension to ensure safe drilling. Ground penetrating radar was used to scan larger areas so that the contractor would have options on placement. We were able to tell the client they were dealing with a 2- way post tension slab approximately 12” thick. We informed the client there was a bottom layer of reinforcement, usually rebar, at about 10”, and a banded post tension bundle, near the wall, that we advised the client not to drill any anchor near. There were also uniform post tension cables every 24”-36” in the other direction. We were also able to identify 2 conduits in the area. All the findings were marked on the slab and depths were provided if they were within 5” (max embedment depth). We came back to the site about three weeks later for a different scope of work and the trash compactor was successfully installed with no issues, slow downs, or additional cost.
