Who We Are

SubAerica is an engineering team focused on non-destructive subsurface imaging. We pair modern GPR systems with positioning (wheel encoder, GNSS/RTK) and post-processing to deliver 2D profiles, 3D slices, and CAD/GIS deliverables.

Headquartered in India, operating nationwide.

Why GPR?

It detects both metallic and non-metallic targets by measuring changes in dielectric permittivity—so PVC pipes, voids, and rebar all leave a signature.

  • No drilling or coring required.
  • On-site decisions with live profiles.
  • CAD/GIS layers for design teams.

Where It Shines

  • Pre-excavation utility mapping
  • Concrete QA/QC (rebar, PT ducts, cover)
  • Pavement & bridge deck condition
  • Archaeology & cultural heritage

Honest Limits

  • Clayey/wet soils attenuate EM signal
  • Depth needs velocity calibration
  • Operator technique influences data quality
We combine GPR with records, EM locators, and selective verification for robust decisions.

Methods

  • Planned grids and line spacing aligned to targets
  • Dual/variable antenna frequencies for depth vs resolution
  • Encoder & GNSS/RTK for positioning
  • Processing: dewow, background removal, gain, band-pass, migration
  • 3D gridding & depth-slice interpretation

Quality Assurance

  • Calibration scans & velocity estimation (hyperbola fitting)
  • Field notes with photos and control points
  • Independent review prior to issue
  • Version-controlled deliverables (DXF, SHP, PDF)

How We Deliver

We start with your decision: what must be known, to what confidence, by when. Then we design the survey, collect data, and deliver tidy CAD/GIS layers, annotated profiles, and an executive-friendly PDF.
