The Importance Of Utility Locating

Underground Utility Locating is important anytime you are going to break ground on a property or job site. Utility maps identify what type of underground cables and pipes are running through the site and their location. These utilities include power cables, gas pipes, water, telecommunication cables, storm drains, and abandoned/unknown underground services. Our underground utility locating services aim to give you a comprehensive report of what’s underground, helping you ensure a safer work environment and avoid preventable utility damage. Once our team have identified and marked out the locations of your detectible underground cables and pipes, we can then arrange the utility mud mapping process.

We have a dedicated team of DBYD Certified utility locators. Infraserv uses both electromagnetic cable locating and ground-penetrating radar (GPR) technology to designate underground utilities.

  • EML Locating – Used to locate conductive utilities such as metallic pipes, electrical and communication cables
  • Ground Penetrating Radar – Used to locate non-conductive material such as Poly or Nylon gas lines, blue brute and uPVC water mains, empty conduits, underground storage tanks and possible underground voids
  • Traceable Rod with EML – Used to locate accessible empty pipes or conduits i.e. sewer and storm water pipes and empty conduits.

Common Utility Locating Questions

Why should I use utility locating services before digging?

Any excavation, irrespective of size, has the potential to damage assets located around the work site, leading to service interruptions, delays to the project, costly repairs and in the worst case scenario, injury or death.

Obtaining information from what is under the surface significantly minimises these risks by providing information about the work site. Safety is a fundamental aspect of any excavation project and so utility locating services should always be the first point of contact: The Essential First Step.

Who should use utility locating services?

Builders, contractors, farmers, excavation companies, councils, landscapers, underground network maintenance workers, plumbers, home owners, cable and pipe location companies – in fact anyone who intends to work around any infrastructure asset(s) should lodge an enquiry with Infraserv before commencing works.

Are underground utilities installed in a straight line?

No. Mainly due to obstacles that may have been in the vicinity when the cables or pipes were installed. And NEVER assume the depth or alignment of pipes and cables. Due to the possible deviation in alignment, manual excavation (if instructed by the asset owner) may be required to determine the exact location of infrastructure assets to avoid any mishaps.

Could I be financially liable if damages were to occur to infrastructure networks?

Yes, court proceedings may commence against individuals and / or companies for the recovery of cost of repairing or reinstating damaged assets where negligence appears to be a contributor.
