What Is GPR Scanning?
Ground Penetrating Radar (GPR) scanning is a non-destructive subsurface detection method used to identify underground utilities, buried objects, voids, and structural features without excavation. GPR equipment sends electromagnetic radar signals into the ground or concrete and analyzes the returning signals to identify changes beneath the surface. This makes GPR useful for construction, excavation, utility locating, surveying, and infrastructure projects.
GPR can help locate electrical conduits, water and sewer lines, communication infrastructure, rebar, post-tension cables, voids, and other subsurface features. It is especially valuable when existing utility records are incomplete or when the exact location of buried or embedded infrastructure is uncertain. Before drilling, coring, cutting, trenching, or excavation, GPR scanning can provide important subsurface information that supports better project planning and helps reduce the risk of encountering unexpected obstacles.
At Utility Locating & Mapping New Hampshire, our GPR scanning services can support residential, commercial, construction, engineering, surveying, and infrastructure projects throughout New Hampshire. GPR can be combined with Private Utility Locating, Utility Marking, Underground Utility Mapping, Concrete Scanning, and GPS/GIS Mapping for a more comprehensive assessment. GPR performance can vary based on soil conditions, moisture, material composition, depth, and site conditions, so results should be interpreted by experienced professionals.
When Is GPR Scanning Necessary?
GPR scanning is necessary when underground or embedded features need to be identified before construction, excavation, drilling, or concrete work. It is especially useful when utility records are incomplete, outdated, or unavailable, or when the exact location of buried utilities and subsurface structures is uncertain. GPR can provide valuable information without requiring destructive excavation.
GPR scanning is commonly used before excavation, trenching, drilling, coring, road construction, utility installation, and site development. For concrete projects, it can help identify rebar, post-tension cables, conduits, and other embedded objects before cutting or drilling. This information can help contractors plan work more effectively and reduce the possibility of unexpected underground or structural obstacles.
For projects in New Hampshire, professional GPR scanning can be particularly valuable when working around existing infrastructure or in areas where subsurface conditions are difficult to determine from surface information alone. Utility Locating & Mapping New Hampshire can combine GPR with Private Utility Locating, Utility Marking, Underground Utility Mapping, Concrete Scanning, and GPS/GIS Mapping to provide a more complete understanding of site conditions before work begins.
What Is Required For GPR Scanning?
GPR scanning requires clear access to the area being investigated, along with basic information about the project and the type of subsurface features that need to be located. Before scanning begins, the site should be reasonably accessible and free from unnecessary equipment, debris, vehicles, or other obstructions that could interfere with the scanning process. Providing available utility plans, site drawings, or previous survey information can also help technicians understand the area.
For underground utility detection, technicians need enough surface access to move the GPR equipment across the investigation area. For concrete scanning, the surface should be accessible and reasonably clear so the equipment can be moved over the concrete. Project details such as the work area, planned excavation or drilling locations, expected utility types, and required scanning depth can help determine the appropriate equipment and scanning approach.
At Utility Locating & Mapping New Hampshire, our team evaluates the site conditions and selects the appropriate GPR scanning equipment and detection methods for the project. Soil composition, moisture, surface materials, utility depth, reinforcement, and other site conditions can affect GPR performance. Combining GPR with Private Utility Locating, Utility Marking, Concrete Scanning, Underground Utility Mapping, and GPS/GIS Mapping can provide more comprehensive subsurface information before construction or excavation begins.
Our Reviews
What Our Customers Have to Say About Us!
Excellent utility locating service. The team was professional, responsive, and provided accurate information about the underground utilities on our property. Their mapping made our project much easier to plan.
We needed underground utility lines located before starting construction, and the process was smooth from start to finish. The crew arrived on time, worked carefully, and explained the findings clearly. Highly recommended.
Very impressed with the quality of the utility mapping and locating work. The team used professional equipment and provided detailed results that helped us avoid potential issues during excavation. Great service and communication.
