For work potentially involving excavation around live underground services, a ground penetrating radar survey using (GPR) technology is ideal for identifying what’s underground prior to excavation. Using a two tool approach, assessing the land with a cable location tool followed by a full GPR survey, detailed information can be gathered about pipes and services underground.
What does a Ground Penetrating Radar (GPR) survey entail?
- With the use of the cable locating tools (RD8000) and generator, the area is scanned to single out the obvious services first which would normally be the metallic material.
- The area is then then scanned with the GPR unit (RDS Detector Duo) to accurately locate the first findings and look for the non-metallic material i.e. gas, water, ducting and drainage pipes etc.
- All of the identified services are marked on the ground with marker paint or flags to show their line and depth.
- On completion of the GPR survey the information is recorded by a GPS survey and can be presented to our clients via a CAD drawing. (Pier UK can also provide a full Topographical survey if required.)
Other uses for this equipment are for locating:
Underground tanks, manholes, pits, voids, steel reinforcement in concrete and many more.
Pier (UK) Ltd can supply GPR equipment and the RD 8000 & generator on a self-operated hire with durations to suit your requirements. Training can also be provided.[call_to_action_bar buttonText=”Contact us” buttonUrl=”https://www.pier-uk.co.uk/contacts” title=”Interested in a GPR survey for your site?” excerpt=”Our expert team are on hand to discuss your requirements.” /]
