Our concrete scanning, digital x-ray imaging, and utility locating services allow our customers to identify subsurface objects or hazards before they excavate or cut into concrete. This yields a variety of advantages:
- Reduce your safety risk, keeping everyone on the job site safe
- Reduce financial exposure
- Save time, knowing exactly where to cut or drill to avoid hazards and costly delays
Over the last quarter century, contracting firms, engineers, and government agencies have come to trust Penhall first for safe and precise technology services.
CONCRETE SCANNING (GPR)
Penhall uses ground penetrating radar (GPR) to detect hazards in concrete. Our concrete scanning service is your first step before concrete cutting, coring, or breaking.
What we find:
- Pipes & Conduits
- Post Tension Cables
- Rebar & Rebar Patterns
- Voids Within Concrete
- Structural Integrity of Concrete
DIGITAL X-RAY IMAGING
Penhall Technologies proudly offers industry leading advancements in x-ray imaging with our digital x-ray solution. Unlike traditional x-ray services which use highly toxic isotopes, our x-ray machine can be turned on and off, eliminating the risk associated with constant exposure to radiation. We also capture images digitally, which increases our productivity compared to using film.
Penhall radiographers who perform concrete x-ray services undergo specialized training and certification. Due to our service industry, and our position as the nation’s leader in concrete solutions, our technicians are completely knowledgeable of common and not-so-common on-the-job hazards, and the safety procedures to be followed.
What is digital concrete x-ray imaging?
Digital concrete x-ray imaging involves the non-destructive use of hard x-rays or gamma rays to image the interior of a concrete target to identify and locate rebar, conduit, post tension cables and other embedded objects.
The differences between concrete x-ray and GPR imaging include:
|Access to both sides?||NO||YES|
|Resulting Image?||NO IMAGE||CLEAR IMAGE|
We recommend using x-ray imaging when you need to:
- Definitively identify the location and type of hazard in concrete
(Is it PT? Rebar? Conduit?)
- Inspect green concrete, as moisture makes GPR less effective
- Core or cut in a congested area
- Maintain operations without extended shutdowns
PRIVATE UTILITY LOCATING
Utility locating, which involves identifying and labeling underground utility lines, allows you to detect and avoid striking subsurface hazards during construction or excavation. Penhall Technologies provides private underground utility locating services nationwide.
We locate utilities on private property, while 811 locates public utilities from the street to the meter. After locating your utilities, our analysts mark each line with paint and/or flags in their designated color in accordance to the APWA.
What utilities can we locate?
- Gas Lines
- Power Lines
- Communication Lines
- Sewer Lines
- Cable Lines
- Underground Storage Tanks
- Underground Pipes
Why use utility location services?
Cost savings! Utilities are everywhere. According to the Common Ground Alliance, there are more than 20 million miles of buried utilities in the United States. For every dollar spent on utility locating, a project will average $4.62 in cost savings. Projects are estimated to save about $1 billion nationwide every year thanks to the use of utility location services.
Another critical reason for utilizing utility location services is to ensure the safety of your crew and site. Striking a subsurface object can cause serious injuries to you or workers on the site.
FIBER-REINFORCED POLYMER (FRP)
Penhall is a certified applicator of fiber-reinforced polymer (FRP), a structural reinforcement method.
It is a non-destructive solution that provides support of added loads, upgrades to meet new code requirements, and protection against earthquakes and other natural disasters.
This combination of a durable epoxy and high-strength fiber create the FRP system. The FRP system is bonded to or wrapped around structural elements to create a surface-mounted reinforcing system.
Benefits of FRP include:
- This lightweight, high-strength solution gives you the flexibility to apply virtually anywhere while causing minimal disruptions to existing conditions.
- Reinforcement solutions can be used for seismic retrofit, non-intrusive/rapid repair, concrete restoration, increased load capacity, or change of use/change of code.
- FRP can be used to strengthen columns, walls, beams, slabs, and unreinforced masonry, just to name a few possibilities. Applications are versatile and can be placed indoors or outdoors.
Often when Thompson has used Penhall it has been in an outage situation where safety, timing, and production are paramount. Penhall has always successfully completed the work on time and within the agreed upon budget. They have a meticulous attention for detail, a great regard for safety, and are readily available and willing to answer any questions. With their numerous years of experience, they were more than capable of thoroughly handling any problems that arose.
In my opinion, Penhall would be an excellent choice to be considered as a critical team member of any industrial construction project.

Penhall Company has always been on the leading edge of technology, this (digital x-ray) is just one more example.
I contacted [Penhall] for 2 floor scans on [a] 5th floor room. [They were] able to come and complete the work needed by [the] afternoon. We thank Penhall for always being accommodating for our project success

The scan done of our existing slab saved both the owner and myself money and headaches. The scanned lines were undocumented power lines for future expansion. If we would have hit those lines it would have been a mess and would have not only cost our project money, but also the project in the future that is planned for those lines. Thank you for what your team did.
The work performance of Josh, Henry, and other crew members has been exceptional. The crew arrives on time and prepared to work. The Penhall crews have met or exceeded expectations during their time on the project. I was fortunate enough to witness several operations, including the rebar scanning, which turned out to be a new learning experience for me. Karina took the time to teach me how the rebar scanning device worked. In addition, Penhall crews assisted with resolving any unknown issues that presented a challenge. For example, Henry played an active role in resolving issue of avoiding rebar during the coring operations and minimized any potential impacts.
The communication efforts between BZJV staff and Penhall demonstrated true partnering between contractor and sub-contractor and to the success of all. I personally enjoyed working with Penhall and look forward to continuing the working relationship in the future.
Just wanted to drop you and your team a line of appreciation on the great service Penhall provided on the bridge deck grinding needed for our project.It truly was a pleasure working with Penhall glad the company keeps the people that help them be successful from state to state. Thanks again for your service.
