Systems pair up to provide a powerful mapping tool

When you are walking the streets do you ever stop and think what could be just a few inches below your feet?
Over recent years, pressure on the built environment has grown as more and more excavation work takes place.

When you are walking the streets do you ever stop and think what could be just a few inches below your feet?
Over recent years, pressure on the built environment has grown as more and more excavation work takes place.

As a result, Atlantic Geomatics has seen an increasing demand for accurate utilities mapping and have been at the forefront of a number of large projects across the UK.

Using electromagnetic detection and ground penetrating radar (GPR) Atlantic Geomatics is able to trace a huge range of underground services. Combining these two techniques, together with existing record drawings and information, provides the most accurate and complete survey data.

Over the past few years GPR systems have become much more advanced helping to locate not just metal services but also plastic ones, which would be undetectable through standard electromagnetic
survey methods.

The accuracy and depth of the survey depends on a number of limiting factors.

Factored in

Ground conditions, the size and depth of services and the proximity to solid objects all affect a ground survey and are factored into results.

Other advances include the use of CCTV cameras and sonde’s allowing services to be located up to depths of 15m. By attaching the sonde or camera to a mobile device, smaller and often older pipework can be traced safely from above ground. The signal emitted from the sonde is traced above ground to improve accuracy of tracing and depths of services.

In order to be certain of what lies beneath trial holes form an essential part of any project and Atlantic Geomatics has partnered with a number of firms to bring its clients the complete package.

Following any utilities survey all services can be traced directly onto the ground reducing delay in any works to be carried out. The full survey is then presented on an existing record drawing or a new one made up clearly showing the type of service found and the depth.

When any excavation work is required it is worth remembering there is a world beneath our feet and to prevent costly delays in both time, money and safety an accurate utilities survey is essential.
