Ground Penetrating Radar

GPR Equipment Catalogue

Build your stack: choose the antenna for depth vs detail, pair it with a rugged control unit, add precise positioning, and finish with 2D/3D software. Everything plays nicely for field speed and clean deliverables.

Antenna Families

Frequency controls the trade-off between depth and resolution. Pick based on substrate and targets; when in doubt, run two bands.

LF: 100–250 MHz

Depth-focused
Low-frequency GPR antenna
  • Geotechnical layers, voids, karst, deep utilities
  • Dry sands & rock: up to several meters
  • Clayey soils: reduced penetration
Typical Depth
3–8 m (site dependent)
Lower resolution

MF: 250–600 MHz

Balanced
Mid-frequency GPR antenna
  • Utility mapping (metal & non-metal)
  • Pavement/base thickness, general subsurface
  • Most urban soils & backfills
Typical Depth
1–4 m
Good resolution

HF: 800–1600 MHz

High detail
High-frequency GPR antenna
  • Concrete scanning: rebar, PT, conduits, slab thickness
  • Shallow utilities and floors
  • Tight grid 0.5 m for 3D
Typical Depth
0–0.4 m (concrete)
Highest resolution

*Depth depends strongly on soil conductivity and moisture. Wet clays attenuate signal; pair radar with cores or EM for certainty.
