GPR Scanning requires clear access to the survey area, appropriate project information, and professional Ground Penetrating Radar equipment suited to the surface and investigation goals. Before scanning begins, technicians should understand the areas of concern and the planned work, such as excavation, drilling, trenching, concrete cutting, coring, or construction. Available site plans, utility drawings, structural records, and information about known underground or embedded features can also help guide the investigation.

The field process requires a Ground Penetrating Radar (GPR) system that transmits electromagnetic signals into the ground, pavement, or concrete and records reflections from subsurface features and changes in material conditions. The scanning surface should generally be accessible so the equipment can move across the required area. Depending on site conditions, GPR may help identify detectable pipes, conduits, underground utilities, rebar, post-tension cables, voids, and other subsurface or embedded features. Results can be affected by factors such as depth, soil composition, moisture, concrete conditions, and target material.

After scanning, the collected GPR data must be reviewed and interpreted to identify patterns or reflections that may represent subsurface features. Findings can be marked on the surface, documented for project records, or combined with other utility locating and mapping methods when appropriate. Proper equipment, experienced interpretation, and clear project requirements help produce useful information for excavation planning, concrete work, construction, renovation, maintenance, and infrastructure projects, while reducing uncertainty and potential conflicts during the work.
