Detection of Reinforcing Steel
We use GPR technology to locate post-tension cables and/or rebar within concrete prior to core drilling for electrical outfitting, plumbing, duct work, fire protection services, and drain installation. Once GPRC has located the reinforcing steel in your concrete structure, we will map a grid onto the surface of your structure to guide you as you drill. Utilizing this service will prevent damage to the integrity of the structure as our non-invasive technology eliminates the need for repair or patching work. Additionally, taking advantage of our expertise will minimize your risk of on-the-job injuries, accidents, and delays.
Detection of Embedded Electrical Services
We will use GPR to locate electrical services and/or conduit running within or below concrete structures in locations such as retail centers, hospitals, and manufacturing facilities. Working with GPRC prior to drilling or cutting into concrete slabs on sites like these will allow you to avoid the hassle of a building or facility shut-down due to electrical outage or failure during the job.
The subgrade below the floors of manufacturing and industrial facilities wears over time from the repeated impact of machinery, erodes or washes out from broken sewer or water lines, and/or settles over the life of the structure. The absence of subgrade creates air pockets undetectable on the concrete surface and increases the possibility of a dangerous and expensive floor collapse. Our GPR techs will locate these problem areas without any damage to the existing structures, thereby preserving the areas as they investigate. Additionally, this service will allow the repair and remediation processes to focus solely on the areas where void cavities exist instead of drilling multiple holes to determine the presence and extent of voids.
Training and Safety:
Safety is a top priority at GPRC. All of our technicians receive extensive on-site training, attend a mandatory manufacturer’s training course, and complete OHSA 10-hour construction training. Specifically, our new techs ride with senior technicians to observe each application and learn to interpret the GPR data. After completing the manufacturer’s training course, the techs will return to the field with the senior technicians who now act in a supervisory role as the techs hone their skills and prepare to enter the field fulltime.
Concrete Scanning - Before you start coring, cutting or demo of concrete find out what is below. Perform a ground penetrating radar scan to find post tension cables, power conductors, fire alarm cabling, rebar, conduit and much more.

Don’t X-Ray your concrete!! Ground Penetrating Radar is not the same as Concrete X-Ray. Concrete X-Ray is time consuming and emits radiation which can be dangerous. GPR uses radio waves to produce the same visual result with no need to develop films and with no health hazards. We can scan your concrete with workers on site during normal business hours.
GPR has been used since 1970, first in geophysical fields and later in construction projects. Though the technology is called ground penetrating radar, the scanning process is completely non-invasive. The technology that we use at is the latest possible technology available developed by years of international GPR research and manufacturing. That gives us the clearest look at what needs to be avoided for your concrete cutting and coring needs. We offer both 2D and 3D imaging.
We specialize in providing accurate scans for concrete structural forms in commercial and government buildings. We are accustomed to government and high rise security procedures and loading dock protocol. Our technicians have passed federal background checks. We have worked for hundreds of customers including sites at Atlanta most high rise buildings in Atlanta. We are the preferred local scanning company because we keep a great service oriented attitude.

Advantages of GPR over X-ray
Access to one side is needed for GPR while x-ray requires access to both sides.
GPR is a safe non-destructive survey that has no radiation hazards.
GPR can give you real time results with a direct read out of x-y locations. X-rays must be processed and then calculated.
A GPR survey can be performed at any time without disrupting any other operations and during normal working hours unlike x-rays.
Thousands of square feet can be scanned in one day whereas X-rays are performed in a step and repeat method limiting the number that can be performed in one day.
There is a lower cost associated with GPR due to set up time, no overtime unless requested, and the amount of scanning that can be performed in one day.
field experience, a wide range of top quality equipment and proprietary software we provide unmatched accuracy to scan concrete walls, ceilings and columns to:
Locate rebar – map rebar spacing and depth in concrete, including slab-on-grade with multiple layers of rebar/other embedded elements.
Locate conduit – map plastic and metal conduits with precision to avoid damage when drilling, cutting, or coring.
Locate post-tension cables – map post-tension cables with precision to avoid damage when drilling, cutting, or coring through post-tensioned concrete.
Locate voids – locate voids under concrete structures, behind walls, in tunnels, etc.
Measure slab thickness – determine and record the slab thickness for both slab-on-grade and suspended slabs, determine rebar depth to measure concrete cover in slabs, beams, and columns
A1 Concrete Cutters is a structural scanning company using the most advanced and mobile, Ground Penetrating Radar (GPR) concrete scanning technology. Unlike X-Ray equipment which requires jobsite evacuation and access to both sides of a concrete structure, GPR is a non destructive concrete inspection system that can locate rebar, post tension cables, pipes, and conduit in concrete structures, slabs, floors, and walls. This technology is much safer than X-Rays and can be performed without disturbing areas or occupants of structures. Our GPR surveys provide real time results which identify potential problem areas immediately prior to drilling or cutting into concrete structures
Damaging structural elements such as conduit, rebar, and post tension cable can be dangerous and costly, not to mention the expense of project delays. A GPR survey performed by A1 Concrete Cutters can isolate hazards in your concrete and reduce the risk.
Our services are routinely applied in hospitals, airports, universities, and numerous retail, residential, and industrial construction sites.
Our Concrete Scanning services combine the most experience people with the latest technology and the largest fleet in the region to provide the best service and quickest response time in the industry. Locating embedded objects in concrete prior to concrete sawing, drilling or breaking is vital to avoid embedded or buried obstructions such as reinforcing steel bars (rebar), wire mesh, post tension cables, conduit, utilities, drainage, water lines, radiant floor heating etc... Digital Imaging software allows us to generate a clear view of the concrete slab or wall for post survey data processing, review and analysis for pre-design and engineering purposes. we offer everything you need to safely scan before you cut.

Requires one-side access
Radar-based concrete scanning is the state of the art in concrete inspection technology, and provides the accurate results that you need when dealing with structures within concrete.
Our concrete scanning system locates structures embedded within concrete slabs prior to drilling, cutting or coring, to a depth of 24 inches or more. A 32" x 32" area of concrete can be inspected and its contents accurately marked in just five minutes. Only single-sided access is required to perform concrete scans (as opposed to X-ray inspection, which needs access to both sides), and thousands of square feet can be inspected in a single day. Faster, safer, and less expensive than traditional X-ray radiography, radar concrete scanning is the best method available for determining what objects lie inside concrete slabs – and exactly where they are.
Radar-based concrete scanning is much better – and much cheaper – than the old X-ray radiography method of locating obstructions in concrete for a number of reasons:
Concrete scanning is quick to set up and only needs access to one side of the slab; X-ray setup can take hours, and it requires access to both sides of the slab.
Data is collected rapidly with concrete scanning, and scans are available for viewing immediately; radiography takes time – and expensive film – to shoot, and then requires development before it can be viewed.
Concrete scan data and images are digital and copies can easily be sent to anyone who needs them; X-rays are on film and must be physically passed around.
Concrete scanning uses harmless, non-ionizing radio waves to gather data; radiography uses X-rays, which present a radiation hazard requiring the evacuation of the worksite.
Exact location and depth measurements of any objects within the slab are immediately available with concrete scanning; radiography requires careful measurements and calculations of the developed films to obtain location and depth data.
As an example, the picture at left shows Glen scanning a section of concrete floor at the Portland International Jetport. This particular section of the Jetport is warmed by radiant-floor heat pipes buried within the concrete: it's very comfortable heat, but the heat pipes make it tricky to work in the concrete without hitting anything. When the need arose to cut some cores into the concrete, we came in with our concrete scanner and found a safe place to core that dodged all of the radiant heat pipes - and rebar.
For years, the only way to perform subsurface structure location on concrete was to use X-ray radiography. Trouble is, X-ray concrete inspection requires lengthy preparation, the evacuation of the work site, and a great deal of time to actually shoot, develop and interpret the films. Not only does this limit how much area can be covered in a day, it drives the price up. Using our portable concrete scanning unit, we can quickly survey a large area at any time, with no radiation exposure risks and no need to clear crews from the site. Plus, we can immediately mark right on the concrete where obstructions lie and where the clear paths through the slab are. It's the fastest way we know of to dig safely through concrete.
