In your industry, you might hear the term “GPR” thrown about a lot. Perhaps you have a vague sense of what it is or how it works, or perhaps it is totally new to you. GPR stands for Ground Penetrating Radar, and it is a process of using radio waves (radar) to locate things underground or embedded in concrete. It is a vital process in many industries to save time and money and to keep people safe. Read on for a better understanding of the basics of GPR and why it is important.
What Is GPR?
GPR is a technology that sends out radio waves into the ground or the concrete slab that you are studying and then receives them as they bounce back. Radio waves can pass through some materials, like soil and cured concrete, but bounces off of others, like rebar or conduit. The data gathered by the GPR device can help you locate dangerous or costly things under the ground before you hit them when digging.
How Does GPR Work?
GPR scanning is usually done in three stages. The first step is for the skilled GPR operator to assess the area that needs to be scanned. Next, the GPR device collects the data about what is embedded in the ground as the technician navigates it over the study area. Afterward, the data is analyzed and interpreted and GPR professionals can map out the exact locations of buried objects, and mark them on the ground or the slab as needed. The entire process is fairly quick and can save a lot of time and money compared to digging to figure out where things are.
How Is GPR Used?
Many industries make use of GPR, from contractors to forensic scientists. GPR is often used to check cured concrete slabs or walls for dangerous objects before cutting or drilling. Contractors, plumbers, and even electricians often find that it is worth the time to have the concrete checked rather than risk injury or damage to their equipment. GPR is also often used to locate buried lines or tanks without disrupting the soil, and to monitor bridge decks for deterioration or inspect roadways. There are many valuable uses for GPR across many industries.
