Tucson Concrete Scanning Projects That Penhall Technologies Has Worked On


Scanning shows hazards previous to coring

During the month of June, Penhall Technologies was hired at a water treatment plant to do concrete scanning services. This was being done in preparation for Penhall Company, their operators were scheduled to drill a 3″ core in a control room that had many transformers, electrical control modules, and conduits within the proposed slab. First, our GPR analysts scanned two locations, in which the customer wanted to put the core. However, our analysts  found presence of conduits, rebar, and structural support. This meant that the client was unable to core where he ideally wanted it. Our skilled analysts were able to find a spot across the room to successfully core into concrete without hitting rebar or conduit. For the client, this was a breath of fresh air. Previous to the scanning, our client was concerned of a conduit strike. He immediately contacted his supervisor to inform him of such and to ensure that no emergency shut down happened on site. Our analysts were able to save time and money for our customer. If our analysts had not been able to locate a safe location, the client would of had to be forced to do an x-ray service, which is usually more expensive and time consuming.

Ground penetrating radar used to locate septic tank lid

ground penetrating radar used to scan concrete
In Marana, AZ, Penhall performed concrete scanning to identify any obstructions on a 4′ x 4′ section. We were able to locate a 13″ thick tank lid prior to cutting a 10″ x 10″ opening.

Locating post tension cables by scanning before drilling
Before cutting into concrete, it is important to locate the post tension cables. In this particular project in Tucson, AZ, Penhall used GPR to ensure that it did not contain any post tension cables before core drilling in 2 areas.
