Utility Survey

We are able to locate and plot the majority of buried services.  Underground

metallic services are detected by using equipment that picks up electromagnetic

waves conducted by pipes and cables.  A signal generator is also used to pass

a fixed frequency signal into services we can directly connect to such as stop

taps or exposed telecom cables.

To detect non-metallic services

we can use ground penetrating

radar (GPR) which operates by

sending a radar signal into the

soil to detect changes in ground


Prior to visiting site we can

undertake a desktop mapping

exercise whereby we contact the

relevant utility companies in a

given area and compile a record

of all known services.  These

records, along with all services

physically located on site can be

surveyed and plotted on our

topographical survey.
