Two Markets, One Mission

Different Conditions, Same Precision

Every region has unique subsurface challenges. We’ve invested in understanding both — so you get a team that knows your local conditions, not generic scanning from a national chain.

🏔️ Washington / PNW

The Pacific Northwest’s seismic construction codes, wet clay soils, and dense urban development create scanning challenges that require local knowledge and experience.

  • IBC Seismic Design Category D reinforcement
  • Glacial till & clay soil GPR calibration
  • Sound Transit & infrastructure coordination
  • Historic building renovation scanning
  • Mixed wood/steel/concrete structures

🌴 Florida / Central FL

Central Florida’s post-tension slabs, karst sinkhole geology, hurricane-rated construction, and high water tables demand specialized GPR expertise that inland-focused companies miss.

  • Post-tension cable detection (FL standard)
  • Sinkhole & karst void screening
  • High water table signal calibration
  • Hurricane-code dense reinforcement
  • Sunshine 811 gap — 60%+ private utilities
