A building renovation lets an older structure accommodate the needs of a growing business. While a visual inspection will identify obvious exterior problems, it won’t reveal issues beneath the surface. Using a ground-penetrating radar system will ensure your building is ready for remodeling by pinpointing areas that need repairs or structural changes. The experts at Haggith’s Structural Scan & Inspection in Kaneohe, HI, provide noninvasive building inspection services on Oahu and explain how these systems work.

What a Ground-Penetrating Radar System Does

Ground-penetrating radar (GPR) systems use radio signals to reveal what’s underground, in walls, or beneath concrete. GPR systems emit radio waves that penetrate the surface and bounce back. A computer measures the depths the waves reach before they return to the receiver, creating an accurate depiction of areas of a building you cannot see. If a ground-penetrating radar system detects an object or obstruction, the waves bounce back more quickly, creating a visible change to the data on the computer screen.

How It’s Used for Building Renovation & Repair

Though GPR systems are commonly operated outdoors, they can be used inside buildings or on concrete slabs to check for damage to the substrate and walls. A technician using a hand-held ground-penetrating radar system will scan small sections of the concrete to determine whether objects are in the way. This is particularly useful during renovations because it confirms the locations of pipes, electrical wiring, and load-bearing support beams. A skilled technician will interpret the data gathered during GPR scanning to provide an accurate picture of a structure.
