While other companies diversify their services, GPRS only specializes in the latest GPR technology, offering expert data interpretation and unmatched experience in the field of concrete scanning. GPRS welcomes small projects and is equipped to handle large jobs, as well. Plus, GPRS is a national company with 19 office locations across 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.
Applications of Ground
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 technicians 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.

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 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 technicians ride with senior technicians to observe each application and learn to interpret the GPR data. After completing the manufacturer’s training course, the technicians will return to the field with the senior technicians who now act in a supervisory role as the technicians hone their skills and prepare to enter the field fulltime.
