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.
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.
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.
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.
Advantages of Electromagnetic Utility Locating
Ground Penetrating Radar Services provides a full suite of electromagnetic scanning and locating services, designed to help provide your team with the most accurate real time scanning data possible. Our project managers are the best in the industry at scanning and locating subsurface utility lines and hazards. We provide information to help keep your team safe and keep you from spending on unnecessary repairs.
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.
GPRS Usage and Affecting Factors
Ground penetrating radar (GPR) is a key tool in detecting the location of underground utilities and other subsurface elements. GPR units contain at least one antenna which is moved over the ground surface being investigated. Several types of units of varying strengths may be used depending on the needs of the project in question. 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 GPRS Mission
GPRS is the nation’s leading ground penetrating radar (GPR) service provider. As the largest GPR company in the U.S., we specialize in providing concrete scanning and utility locating services to identify unknown subsurface elements. Our Project Managers are extensively trained to handle all possible scenarios, making them experts in their field. With offices in all major hubs across the U.S., our team members can quickly mobilize to a site in order to identify any unknown subsurface elements impacting your project.
The GPRS Difference
What sets a GPRS Team Member apart?
The key to GPRS’s success is our employees. Our team members are the best in the industry, and it is for this reason that we have been able to achieve such growth. Some of the key qualities which set our team members apart include: Integrity, competency, team work, continual growth, problem solving mindset and commitment to the customer.
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.
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 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 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.
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.
