Locating Rebar At The Orlando International Airport
understand what's underneath trademark trinity subsurface

Trinity mobilized to Orlando International Airport to perform a full Concrete Scan using Ground Penetrating Radar and a variety of Electromagnetic Locating Devices. Earlier in the week, one of the Concrete company's drillers came into contact with some Rebar while Coring. Immediately the drilling services were put to hold, until Trinity was successfully able to mark out the rest of the scope before continuing the project any further. Timely and effectively, Trinity was able to mark out all shown Rebar within the scope. Leaving our clients minds at ease. Grid patterns were performed in Passive Modes with the EM Receiver, specifically to detect subsurface metallic conduit, copper wiring, and live electrical lines (60 Hz). GPR Scans were also performed in a similar grid pattern, purely detecting changes in density and discovering anomalies that are nonconductive to EML. The purpose of this Concrete Scan was to map rebar, post-tension cables, subsurface anomalies, peaks, valleys, and beams in this cinder block wall as well as electric lines, communications lines(Phone, Cable, FOC), water lines, gas lines, sewer lines, etc at this property prior to Coring. The concrete thickness was approximately 12 inches deep in most areas. All findings were marked black chalk according to the UWPA Uniform color code with periodic, approximate depths. Please avoid all marks when Coring.

At Trinity Subsurface, we are able to make sure any obstructions within the concrete are found when performing a concrete locate. Whether your project is to locate prior to saw cutting a trench, core drilling a hole, or locating structural reinforcement prior to drilling for anchor bolts or screws or any other type of concrete penetration, we will be able to locate all obstructions within the floor, ceiling or walls. These obstructions include rebar, wire mesh, post tension cables or even conduits and other obstructions within the concrete. We are also able to locate utilities that run in the concrete or lie directly below the concrete. Using our state-of-the-art concrete locating equipment, we can see thru up to 18-24 inches of concrete depending on the age and make up. We can then provide a detailed written report for your project or just mark it out on the surface of the concrete with chalk, marker, tape or paint. Our training program for concrete locates is very thorough and one of the best in the industry. When our technicians are on site, you can rest easy knowing that they have the best training and equipment for your concrete locating project. Maintaining the structural integrity of your concrete and protecting your project and your people working on it are the number one priority of Trinity Subsurface.
