Illustration of Underground Utility Locating


Private utility locating is vital to any construction, excavation, or renovation project. 811 One Call services locate public utility lines, but do not provide depths for them. Nor do they detect or locate private utilities. Our private utility locating services employ Ground Penetrating Radar (GPR), electromagnetic locators, CCTV video cameras, acoustic leak locators and other equipment to scan for subsurface utilities, including depths and GPS mapping, saving time, money, and even lives by avoiding utility strikes to protect all site employees and contractors from potential line strike damages. GPRS provides complimentary .KMZ files for all of our exterior utility locating projects.

Illustration of Subsurface Pipeline Locating


The majority of pipe defects occur underground in buried pipes that can only be accessed by excavation or CCTV cameras via a Video Pipe Inspection (VPI). GPRS deploys both robotic crawler CCTV cameras and lateral launch cameras and push cameras to document and assess water systems, drains, and conduct sewer inspections without costly excavation. Our NASSCO-certified WinCan VPI reports provide clients the exact location, photo, video, and map of each defect, cross-referenced and tagged with a defect severity level. This allows our clients to visualize every inch of water and sewer pipe within their system and to create comprehensive repair and maintenance plans to repair pipe damage in the most cost-effective manner possible.

Illustration of Post-tension Concrete With Utility Lines


Any project involving post-tension or slab-on-grade concrete contains an inherent risk of costly damage and/or injury when you core or cut into the slab. Rebar, conduit, and post-tension cables pose significant strike risks, and each has its own unique GPR imaging signature. GPRS’ concrete scanning service provides digital concrete scanning with ground penetrating radar (GPR) to accurately pinpoint the location of each hazard and map it in detail, so there is never a question of where you can cut and where you can’t. Unlike concrete x-ray services, GPR concrete imaging does not require you to close off sections of your site to avoid radiation. In most cases, your work can continue while we scan and locate slab reinforcement and conduits with 99.8%+ accuracy, so that you can safely cut and drill.

GPRS Leak Detection Services can quickly pinpoint a known leak when a problem is identified in municipal water or sewer infrastructure or for an industrial facility. We can also proactively search for leaks in domestic water and fire systems, and complete Water Loss Surveys to locate problems before they are evident and costly.

Acoustic leak detection is aided by leak correlation to provide accurate, real-time verification of an active breach and can be integrated with our Video Pipe Inspection Services and utility locating to improve commercial, industrial, and municipal water infrastructure efficiency, and avoid unnecessary excavation. At GPRS we are the best leak locators in the industry because we are backed by the power of our 99.8% accurate underground utility locating process.

What is ground penetrating radar?

You cannot avoid what you cannot see. Ground Penetrating Radar (GPR) is a non-invasive locating tool that allows our SIM-Certified Project Managers to scan post-tension concrete for conduit, rebar, and other encased objects, and to effectively locate utility lines, water and sewer pipes, telecom and fiberoptic cables, and subsurface voids.

GPR functions by sending radar signals into a surface like concrete or soil and capturing that signal as it bounces back to create a specific reading that allows our highly trained Project Managers to determine the length, depth, and type of subsurface feature located.

The various location features can then be marked out on the surface to show the precise location and provide clear boundaries and spaces where you can cut, drill, or excavate safely.

The various location features can then be marked out on the surface to show the precise location and provide clear boundaries and spaces where you can cut, drill, or excavate safely.


Complete facility visualization can almost eliminate clashes, reworks, change orders, and the cost overruns associated with them. 

GPRS is committed to helping you manage and mitigate risk on your job and for your team. We provide complete facility infrastructure visualization through utility locating, concrete scanning & imaging, 3D laser scanning, video pipe inspection, leak detection, drone photogrammetry, and state-of-the-art mapping & modeling services so that you and your team can see potential hazards and design obstacles and mitigate risk to keep your project on time, on budget, and most importantly, safe.

Our goal is 100% subsurface damage prevention, and we have achieved and maintained a 99.8% accuracy rate in concrete scanning & imaging and underground utility locating on more than 400,000 jobs and counting. 

When underground utilities and subsurface features are not accurately located prior to excavation or trenching, your most important asset is at risk – your people. 

When you call GPRS, we use the latest in locating and scanning technology to make sure that we help keep your people, and ours, safe.
