Difference between Concrete X-ray and Concrete Scanning
When it comes to finding out what’s inside a concrete slab, non-destructive options are generally the first choice. The two main options are the use of x-rays or ground penetrating radar (GPR) to “see into” the concrete slab or structure. Both provide a closer look at what’s inside, including rebar, conduit, post-tension cables, and more.
GPRS internal safety program
Safety - Always on Our Radar
Here at Ground Penetrating Radar Systems, safety is our top priority in everything we do.
GPRS is committed to creating and fostering a safe work environment for our team members, and teaching them how to extend that safety to all project sites and our community.
Why it's necessary to call GPRS in order to keep a jobsite safe
Why isn’t it enough to call 811?
While a public utility locating service such as 811 should always be your first call, these services focus ONLY on public utility location. This leaves you with the dangerous potential of hitting any private utilities they failed to locate. Calling a private utility locating service in addition to 811 will ensure you uncover all buried utilities before digging or working in an area.

Subsurface Investigation Methodology
What is SIM?
SIM stands for Subsurface Investigation Methodology. SIM is a standard operating procedure comprised of two specifications created specifically for subsurface investigations- one for underground utility locating and one for concrete scanning.
Subsurface Dangers Below
When penetrating the ground or concrete structures, there are many unknowns that could cause damage to people and equipment. From underground utilities and voids to the reinforcing steel and conduits in concrete, there are a number of potential problems you could encounter from the unknowns.
Locating Water Lines
Water lines can be made out of various types of material, not all of which are conductive. Traditional methods of utility locating are only able to pick up on conductive materials. This leaves PVC and other non-conductive materials beyond the scope of many utility locating services. Ground penetrating radar is capable of finding all types of material regardless of conductivity. This makes it an excellent choice for locating buried water lines.
Locating Gas Lines
Natural gas is used for heating, hot water and cooking among other uses. Pipes carrying natural gas can range in size and material. Most piping used for natural gas lines is made of conductive material, making it more easily identifiable in a GPR scan.
Locating Sewer Lines
Sewer lines are a key utility but are often overlooked by public and even private utility locating services. Lines can be made of a variety of materials, depending on their age and location. The majority of sewer piping material is non-conductive- materials such as HDPE, PVC and even clay are all commonly used. Lines can be decades old, meaning that accurate plans and as-builts are often missing or non-existent.
Locating Buried Electrical Lines
While the majority of electrical lines are found above ground in the United States, there is still a percentage of lines which have been buried below ground. These lines often run from a public box or meter on to private property. As a result they are out of the domain of public utility locating companies such as 811. Buried electrical lines may run alongside buried fiber and other cables, complicating the process of identifying them.

GPRS Project Managers will assess the site and make a determination as to which type of radar is the best fit for the job.
The History of Electromagnetic Utility Scanning
How Electromagnetic Induction Became The Scanning Industry Standard
Electromagnetic technology was discovered by famed British scientist Michael Faraday in 1831, in one of his presentations to the Royal Institute in London. He described not only the process of electromagnetic induction, but hypothesized its use as a measuring device. His paper would lay the groundwork for the first utility scanning and locating tools.
Advantages of Electromagnetic Utility Locating

GPRS Utility Scanning & Locating Tools
GPRS utilizes state of the art technology for all of our private utility locating and concrete scanning needs. Our equipment is the best in the industry, and our utility locating technicians receive continuous training and education on new tools and techniques for subsurface scanning and private utility locating. We’ve highlighted some of our preferred tools for subsurface scanning and private utility locating below.
When to Call a Private Utility Locator
When performing digging and other excavation work it is more common than you would think to encounter utilities buried underground. Public utility providers offer a free “call before you dig” service in which a trained technician visits a site to identify and mark out the locations of public underground utilities. These services are a valuable tool in locating and avoiding hitting public underground utilities.
Why You Should Scan Before You Cut or Core Concrete
Performing work on existing concrete is often a necessary part of construction. Coring, drilling and cutting are just a few of the techniques which are used on concrete slabs and walls. This concrete can contain rebar, conduit, post tension cables and other materials, with the potential to cause major damage if hit.
GPRS & The Evolution of Industry's Technology
GPR uses an electromagnetic pulse to generate data on a computer screen, which can be studied in the field to understand existing subsurface conditions. It was this SIR 2000 and long hours working out of that basement which started the nationally recognized brand of GPRS, LLC.
Flash forward to 2019. GPRS’ focus has still been to continue finding and utilizing the industries newest and most advanced equipment to locate subsurface concerns.
