Concrete Scanning GPR: What Every Commercial Contractor Needs to Know Before Cutting

Image
Concrete scanning GPR is a non-destructive method that uses ground-penetrating radar to locate rebar, post-tension cables, conduit, and utilities inside a concrete slab before cutting, coring, or drilling begins. A single missed utility line can cost a commercial project more than $56,000 once repairs, downtime, and liability are added up, according to the Common Ground Alliance's 2023 DIRT report. That's the kind of number that keeps project managers up at night. Concrete scanning GPR solves this problem before the first cut is made. On a recent high-rise renovation, a scan revealed an electrical conduit sitting inches from a planned core hole — a discovery that took fifteen minutes and saved the crew a full day of downtime. For commercial contractors, this isn't optional anymore. It's standard risk management. What Is Concrete Scanning GPR? Concrete scanning GPR (ground-penetrating radar) sends radio waves into a slab and reads the signal that bounces back. Different...

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...
