GROUND PENETRATING RADAR (GPR)
A GPR (Ground Penetrating Radar) scanner is a non-destructive device that uses radar pulses to image subsurface layers, detecting buried objects like pipes, rebar, voids, and utilities in concrete, soil, or pavement, crucial for construction, archaeology, and utility locating by revealing hidden structures without digging. These handheld scanners send radio waves down, capturing reflections to create real-time 2D (B-scan) and pseudo-3D (C-scan) images, identifying everything from rebar and conduits to plastic pipes and tanks, making them essential for safe drilling, cutting, and excavation

Knowing What Lies Below
When Sarah Mitchell, a homeowner in Carmel, Indiana, planned a backyard renovation—including an expanded patio, a fire pit, and new landscaping—she assumed the biggest decisions would involve design and materials. That changed the moment her contractor asked a critical question:
“Do we know what’s underground?”
Uncertain about the location of utility lines beneath her property, Sarah contacted Util-Locators, a company specializing in Ground Penetrating Radar (GPR) utility locating services. Within days, a trained technician arrived with advanced GPR equipment designed to detect both metallic and non-metallic utilities.
As the radar scanned the ground, it revealed a network of buried electrical conduits and an unexpected water line crossing the planned excavation area. Using this data, Util-Locators provided clear markings and a detailed report, allowing Sarah’s contractor to adjust the design before breaking ground.
The result?
No utility strikes, no costly delays, and complete peace of mind. Sarah’s project in Carmel stayed on schedule, and her backyard transformation began with confidence—rooted in knowledge rather than guesswork.
Our Passion is Your Damage Prevention
Across Indianapolis, a commercial construction firm was preparing for a much larger undertaking: the expansion of a medical office complex. With multiple stakeholders, strict timelines, and zero tolerance for utility damage, accuracy was essential.
The project managers partnered with Util-Locators to conduct a comprehensive GPR survey of the site. Unlike traditional locating methods that focus only on known utilities, GPR allowed Util-Locators to identify unknown and undocumented subsurface features—including abandoned conduits, reinforced concrete, and deeply buried services.
The data was integrated directly into the project’s planning documents, enabling engineers and site supervisors to coordinate excavation with confidence. By identifying potential conflicts early, the company avoided service interruptions, reduced liability risks, and maintained compliance with safety regulations.
For the commercial team in Indianapolis, Util-Locators’ GPR services weren’t just a precaution—they were a strategic advantage.
Our Passion is Your Damage Prevention
Whether supporting a homeowner’s dream project in Fishers, Carmel, or Bloomington, or safeguarding a complex commercial build in Indianapolis, Fort Wayne, or Evansville, Util-Locators bridges the gap between what’s visible and what’s hidden. Their professional GPR services deliver clarity, reduce risk, and protect investments of every scale.
Because no matter the size of the project, knowing what lies below makes all the difference.
Every successful project starts with knowing what’s beneath the surface. This utility map, developed by Util-Locators for Kokomo Airport, uncovers hidden subsurface features to help guide smart planning, reduce risk, and keep airport operations moving forward with confidence.
How GPR Works
GPR systems transmit short pulses of high-frequency radio waves into the ground or concrete surface. When these signals encounter a change in material—such as utilities, rebar, voids, or buried objects—they reflect back to the surface.
Specialized software processes these reflections into clear visual data, allowing trained technicians to identify the location, depth, and size of subsurface features without any cutting, drilling, or excavation.

Frequently Asked Questions
Is GPR safe?
Yes. GPR uses low-power radio waves and is completely safe for people, pets, and the environment. It is non-invasive and does not disrupt the surface being scanned.
Can GPR locate all utilities?
GPR can detect most utilities and subsurface features by identifying changes in material. Results are strongest when combined with experienced interpretation and, when required, other locating methods. Util-Locators uses best-practice techniques to maximize accuracy.
How deep can GPR scan?
Depth varies depending on soil conditions, material type, and antenna frequency. In many applications, GPR can detect features several feet below the surface, and sometimes deeper in favorable conditions.
Do I need GPR for small residential projects?
Yes. Even small projects like fence posts, decks, driveways, or landscaping can result in costly utility damage. GPR helps homeowners avoid unexpected repairs and ensures safer work.
How long does a GPR survey take?
Most residential and small commercial scans can be completed within a few hours. Larger or more complex sites may require additional time, but results are typically available quickly.
When should GPR be done?
GPR should be performed before any excavation, drilling, cutting, or coring. Early scanning helps prevent delays and costly changes once work has already started.
