Asset & Underground Locating Services
We provide comprehensive and reliable underground locating services to help you avoid costly damage to buried utilities. Our certified professionals use the latest technology and equipment to accurately locate and mark the precise location of buried cables, underground pipes and other below surface infrastructure. This allows you to safely dig or excavate around these critical systems, ensuring that your project stays on schedule.
Underground utility locating is the process of using high tech equipment to map out what’s going on underground. Rather than risking damage, a Utility Locator can verify existing infrastructure and manage safe excavation practices for any future projects involving this area.
We have a team of professional and experienced individuals that use radiofrequency locating, and ground-penetrating radar to find pipes or utilities below the surface. We also make use of 3D imaging for an accurate assessment of how deep you need to dig before finding what’s beneath!
Utility Locating
Our underground locating services include utility locating and markings for a variety of buried infrastructure, including:
- Electric cables and power lines
- Gas and water pipes
- Telecommunications and fibre optic cables
- Sewer and stormwater lines
- Utility Lines


Underground Utility Mapping
In addition to locating and marking underground utilities, we can also create a detailed map of your underground infrastructure. This map can be used for a variety of purposes, including:
- Planning future construction projects
- Investigating potential damage to buried utilities
-
Determining the cause of leaks or other problems with underground infrastructure
Ground Penetrating Radar (GPR)
Ground Penetrating Radar (GPR) is a non-destructive imaging technique used to locate and map buried utilities. GPR works by sending electromagnetic waves into the ground, which reflect off of buried objects and are detected by a special antenna. This information is then processed to create a detailed image.
Underground 3D Imaging
In addition to GPR, we also offer a state-of-the-art underground imaging system that can create a three-dimensional (3D) map of buried utilities. This system, known as terrestrial laser scanning (TLS), uses lasers and sensors to collect millions of data points about the ground surface and what lies beneath it.
CCTV Inspections
CCTV inspection is a common method used to inspect sewer lines and other buried pipes. A small camera is inserted into the pipe, which transmits live video footage of the inside of the pipe to a monitor. This allows our team to quickly identify any problems with the pipe, such as blockages, cracks or breaks.
