GPR Enables the Location of Buried Utilities
Typical GPR Response from a Buried Utility Low
amplitude response is interpreted to be due to
the utility being a PVC pipe.
Increase in plot scale to highlight response.
The low amplitude response is interpreted to be
due to the utility being a PVC pipe.

Advantages of Using a GPR Cart System

• Allows multiple GPR antennas to be deployed along
  the same profile, reduction in data collection
  time.
• The GPR survey can investigate construction
  details and also locate services with the one
  data collection event.
• Location of voiding and engineering information
  can be gained from the GPR profiles by the use of
  multiple antenna frequencies.

12
Mala GPR Systems

• Any configuration of Mala GPR Systems can be used
  with the Cart System.
• Individual CX11 (Concrete System)
• X3M GPR control unit and XV11 monitor.
• ProEx GPR system, running 2 (or more) antennas.
