We’ll take a break from the usual GPR educational posts to brag a little bit. And boy, is there a reason to brag!

This is the latest addition to the Oerad Tech family — the Concretto Ground and Wall Penetrating Radar.

Here it is in its entire glory:

The Concretto is a lightweight, portable and sturdy Wall Penetrating Radar (WPR) — an indispensable tool for every construction worker, inspector or repairs man. It offers you:

  • Excellent penetration depth in concrete and brick floors and walls,
  • Knowledge on where to drill without damaging the structure or your equipment,
  • Quick assessment of the stability of a wall, road or bridge,
  • Information on rebars, wires, cables and pipes on the spot.

This little device is an Ultra-Wideband (UWB) shielded pulsed WPR for non-destructive imaging of subsurface structures. It comprises of a transmitter and receiver boards and antennae, a controller board and a distance measurement device.
