Ground Penetrating Radar (GPR) Scanning is a non-destructive testing (NDT) method used to detect and map hidden objects beneath the ground or inside concrete without excavation or damage. Using high-frequency radar waves, GPR scanning accurately identifies underground utilities, rebar, post-tension cables, conduits, voids, pipes, storage tanks, and other buried structures. It provides real-time subsurface data, making it one of the most reliable technologies for construction and utility locating projects.
Unlike traditional excavation methods, GPR scanning allows contractors and engineers to inspect subsurface conditions safely while preserving the integrity of the surrounding area. The technology produces detailed underground images that help professionals make informed decisions before drilling, cutting, coring, or digging. This reduces uncertainty and improves the overall efficiency of construction and infrastructure projects.
At Utility Locating & Mapping Idaho, we provide professional GPR scanning services for residential, commercial, industrial, and municipal projects. Our experienced technicians use advanced radar equipment to deliver accurate underground detection, helping clients prevent utility strikes, protect valuable infrastructure, and complete projects safely and efficiently.



GPR scanning should be performed before any activity involving excavation, drilling, concrete cutting, coring, trenching, demolition, remodeling, or utility installation. Identifying hidden utilities and structural components before work begins significantly reduces the risk of damaging underground infrastructure or reinforced concrete elements.
It is especially valuable for locating rebar, post-tension cables, electrical conduits, plumbing lines, underground storage tanks, voids, and buried utilities that may not appear on construction drawings or existing utility records. Contractors, engineers, architects, municipalities, and facility managers rely on Ground Penetrating Radar (GPR) to improve project planning, increase job site safety, and avoid expensive delays caused by unexpected underground obstacles.
Whether you're renovating an existing building, constructing a new facility, or planning infrastructure improvements, professional GPR scanning services provide the accurate subsurface information needed to complete projects with confidence. Early detection helps reduce repair costs, minimize downtime, and improve construction efficiency.

Successful GPR scanning requires trained technicians, advanced Ground Penetrating Radar equipment, and access to the area being inspected. The scanning surface should be reasonably accessible and free from excessive debris or obstacles to allow accurate radar data collection. Experienced operators analyze the radar signals to identify underground utilities, concrete reinforcement, and other hidden structures with precision.
Providing project drawings, construction plans, utility records, or information about the area of concern can help technicians better understand the project and improve scanning efficiency. While these documents are useful, GPR scanning provides real-time field verification that often reveals hidden features not shown on existing plans.
At Utility Locating & Mapping Idaho, we combine state-of-the-art GPR technology, experienced technicians, and proven scanning methods to deliver reliable results. Our Ground Penetrating Radar scanning services help contractors, engineers, property owners, and utility professionals locate hidden infrastructure, improve job site safety, reduce construction risks, and ensure excavation or concrete work is completed with confidence.

We hired them before starting a commercial excavation project, and their team quickly located all underground utilities with excellent accuracy. Professional service, clear communication, and completed on schedule. Highly recommended.

We needed GPS/GIS utility mapping for a large development site, and the results were detailed and easy to understand. Their professionalism and attention to detail made planning much easier. We'll definitely use them again.

The concrete scanning service saved us from cutting through hidden electrical conduits. The technicians were knowledgeable, arrived on time, and explained everything before starting the work. Great experience from start to finish.
