Choose concrete scanning when…
- The hazard lives inside or under a slab—cores, post-tension concerns, slab-embedded conduit, radiant tubing risk.
- You need mark-out in square feet tied to a floor plan or core schedule.
Start on concrete scanning; antenna tradeoffs for slabs are summarized in GPR antenna frequency: utility vs slab.
Choose outdoor utility locating when…
- The question is plan-view routing across soil, asphalt, or turf—laterals, yard lines, charger trenches, private runs.
- You are pairing with 811 marks but need additional imaging at the work point.
Our umbrella entry is GPR & utility locating, with private-side detail on private utility locating.
When you might need both
