Concrete Scanning GPR: The Contractor's Guide to Safe Drilling and Coring
Concrete scanning GPR is a non-destructive method that uses ground penetrating radar to locate rebar, post-tension cables, conduit, and voids inside a concrete slab before drilling or cutting begins. Every year, thousands of drilling and coring jobs go wrong because nobody checked what's hiding inside the slab. In 2023 alone, professional contractors were responsible for 55.3% of reported underground utility damage incidents, according to the Common Ground Alliance's DIRT Report. Concrete scanning GPR exists to prevent exactly this kind of costly, dangerous mistake. Picture a crew about to core through a parking deck for a new drain line — a five-minute scan reveals a live electrical conduit sitting two inches below the surface. That single scan just saved a project timeline, a budget, and possibly a life. What Is Concrete Scanning GPR? Concrete scanning GPR (ground penetrating radar) sends high-frequency radio waves into a concrete surface and reads the signals that bounce ba...
