Underground Utility Surveying - Frequently Asked Questions

How to Identify Underground Utilities?

Underground utility locating requires the use of a few different methods to accurately mark buried lines. An electromagnetic locator (EML), or pipe and cable locator, is used for tracing utility lines and metallic pipes. GPR is also used to identify other objects that could be present within the ground - we are trusted experts so please contact us today for a quote.

What are Underground Utility Mapping Services?

Utility Mapping is a survey used to identify what lies beneath. Utilities and structures within the ground are located using electromagnetic instruments and GPR to establish location.

What are the Top Reasons to Conduct Underground Utility Surveys?

Underground Utility Surveying is important. They are used to identify where utilities are present within a specific area. The information is then used to aid with any close excavation to help minimise risk while onsite.

What is a Ground-Penetrating Radar (GPR)?

Ground penetrating radar (GPR) is a non-destructive detection and imaging method which identifies subsurface elements either underground or within a surface such as concrete. GPR can detect both metallic and non-metallic objects, giving it a wide range of applications. It reveals all types of utilities, including electrical conduit, steam pipes, telecommunications lines, gas & oil lines, water lines, and sewer & storm pipes. GPR can locate the presence of voids, rebar, conduit, post tension cables, and other structural elements hidden within concrete.

Can GPR go through concrete?

Yes GPR can penetrate through concrete and other materials such as asphalt, made ground, ice and soils. Please contact us today to explain the details of your project.
