What Concretto is
The Concretto is an Ultra-Wideband (UWB) shielded pulsed Wall
Probing Radar (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. The
Concretto system is designed and manufactured by Oerad Ltd.
What Concretto is used for
The Concretto has a wide variety of usages including but not limited to
underground utility detection, non-destructive concrete structure
analysis, rebar detection, road inspection, cracks and faults localiza-
tion in concrete and asphalt structures, wire and pipe mapping in
buildings, etc. It is designed to withstand the harsh conditions of
construction sites.

Startup
• Assemble your system as shown in the Assembly section of this user
manual.
• Attach all cables to GPR and Android device.
• Start up the Oerad Android app.
• Press the power switch on the GPR. Your GPR is running when the
power level diodes light up.
Calibration
• Prepare a 1 or 2 meter long flat surface marking its beginning and
end.
• Place GPR at beginning and start it up.
• Navigate to the Calibration menu in the Oerad app via settings or on
its initial start up screen.
• Press Start and allow the Oerad App access to the USB device if
prompted.
• When you reach the end of the surface press Stop and then Save
• Your distance measuring wheel is now calibrated.
