While other companies diversify their services into unrelated fields and equipment, GPRS specializes in sub-surface investigations, offering expert data interpretation and unmatched experience in the field of concrete scanning. GPRS welcomes small projects but also has the staff and equipment to handle large jobs.
GPRS is a national company with local technicians employees in nearly every major city in the US. This vast network of technicians allows us to respond quickly to job requests, delivering a technician and equipment to your job site in record time. We are able to do this because we do not have to mobilize long distances, and each technician has all the necessary equipment with him. GPRS does not need to rent, borrow, or ship the equipment needed for most jobs.

Ground Penetrating Radar And Concrete X-ray?
When determining cost for your concrete imaging project, these are some considerations:
1. Location of the project and objective of the concrete imaging.
2. What kind of concrete subsurface are we locating (i.e. hollow core, post tension, slab on grade)?
3. How much wire mesh, rebar, and post tension reinforcement is suspected in the concrete?
4. How many locations at the site need to be x-rayed and how far apart are they?
5. If we are going to image a concrete wall or ceiling, will a lift or scaffolding be available for our use or does our technician need to arrange for this equipment?
Applications of Ground
Penetrating Radar:
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 GPRS 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 GPRS 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.
Detection of Voids 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 tech's 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.

To Whom it May Concern,
Let me take this opportunity to provide a exemplory recommendation for Ground Penetrating Radar Systems, Inc. and the professional service they have delivered. Turner was the General Contractor for the 2008 Democratic National Convention in Denver Colorado. We utilized GPRS to ensure safe drilling areas in over 150 locations at the Pepsi Center through very congested floor slabs. The project schedule was extremely tight and the accuracy of the information provided was remarkably very sound. GPRS was instrumental in assisting in a very successful project for the entire design/build team. Turner has since and certainly will continue to use Ground Penetrating Radar Systems, Inc. prior to cutting into existing slabs and walls.
Respectfully,

Deterioration Mapping in Reinforcing Steel
Utilizing the latest software, GPRS will provide a qualitative assessment of your concrete structure by plotting the strength of reflection in its rebar. As we overlay the resulting data directly on your floor plan, you will be able to identify the exact location of bar corrosion and degradation.
GPR Concrete Deterioration Inspection
Below are two examples that represent the color gradient on the left and and on the right the lines of delineation.
Over time, concrete will deteriorate due to elements, the changing seasons, and lack of maintenance, corroding the steel inside of the concrete structure. Left untreated, these conditions will worsen over time. GPRS can determine potential problem areas long before deterioration is visible on the surface or before concrete starts separating and spawling on the underside of the slab, endangering any residents or users of the structure in question. This service is especially valuable for work on parking garages, bridge decks, manufacturing facilities, oceanfront hotel balconies, and any coastal structures
Training and Safety:
Safety is a top priority at GPRS. 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 tech's ride with senior technicians to observe each application and learn to interpret the GPR data. After completing the manufacturer’s training course, the tech's will return to the field with the senior technicians who now act in a supervisory role as the tech's hone their skills and prepare to enter the field full time.
