Orlando Concrete Scanning Projects that Penhall Worked On

Penhall Technologies performs concrete scanning at regional airport

Recently, The Orlando branch of Penhall Technologies was contracted to scan an upper floor of a regional airport. The client wanted to install a new electrical outlet without hitting conduits or post tension cables. Using a 2700 MHz GPR antenna, the Penhall analysts scanned the elevated concrete slab, located utilities, and identified other hazards. In the area intended to be drilled, a conduit run was noted. If not scanned, the customer had the possibility of hitting those conduits while drilling. This could be a detrimental mistake, especially within a place like an airport.  Penhall Technologies assisted in finding an appropriate and safe area to drill for the outlet to be installed. GPR is a safe scanning method that can be conducted near people, such as in a crowded airport, so that business operations can continue as usual while the scan is completed.

Ground penetrating radar used to prevent damage during drilling

Penhall Technologies Orlando recently completed scanning in an office building in Altamonte Springs, Florida. The contractor needed to run drainage for a cooling system in a server room. The contractor was concerned about hitting post tension cables, reinforcing steel, and conduits while drilling. One of our expert scanners used the 2700 MHz GPR antenna to scan 5 different areas and mark out reinforcing steel and conduits in the slab. No post tension cables were noted during the scanning. However, the reinforcing steel and conduits were marked so the contractor was able to drill without damage. Concrete scanning was necessary at this site in order to keep workers safe and ensure the structural integrity of the building remained intact.

Concrete scanning to eliminate the risk of damaging shallow utilities before trenching

orlando-gpr-1A retail space at the Florida Mall in Orlando, Florida was under construction and the contractor was concerned about damaging shallow utilities during trenching. Penhall Technologies was able to scan the 7’ x 17’ trench area using ground penetrating radar. The 2600MHz antenna uses electromagnetic pulses to locate anomalies in and below the concrete slab. After completing the GPR service, a radio detection wand was used to check for live electrical and radio frequency lines. A live electrical line was located just outside of the trench and noted on the surface with spray paint.

Ground penetrating radar used to locate rebar and conduits to avoid hazards when cutting

locate rebar and conduit before cutting into concrete slabPenhall Technologies Orlando office used ground penetrating radar to scan a concrete slab in Maitland, Florida. The customer was installling electrical conduits to supply power to 2 smart car kiosks just outside of a parking garage. The analyst specializing in concrete scanning was able to determine that the customer was safe to saw cut without damaging any structural reinforcement or conduits. GPR scanning is a quick and accurate way to keep the project safe and on time. The GPR unit also can locate post tension cables, rebar, wire mesh and pvc pipes in concrete. GPR is a safe alternative to X-Ray, it delivers no radiation with half the setup and processing time.
