Service Clearance & Marking Out Survey
As well as carrying out a full utility mapping survey, Geotec provide CAT scans whereby the position, type and depth of buried services & utilities are sprayed onto the ground surface.
Geotec can either survey a whole area or provide service clearance for numerous invasive ground investigation (GI) areas or positions. This includes borehole, window sample, trial pit or core sample locations.

Although a drawing is not provided, the methodology used is the same (use of EML, cover lifting and GPR) as for any other utility mapping survey with GPR targets sprayed onto the ground surface in real time.
A mark out survey provides a cost–effective alternative when smaller excavations are planned, such as the installation of bollards, signs and flag poles, or to mark–up services prior to cable route installations.

Mapping
An example of a survey where several unidentified ground penetrating radar targets are present, along with confirmed buried services and utilities.
This tool also enables confirmation of the presence of metallic and conductive services that have already been detected through radio frequency detection/electromagnetic locating (RFD/EML).
