Centerline provides extensive line locating and underground facility locating services across Alberta. Our team of experts identifies buried infrastructure to ensure your project remains safe and compliant with ground disturbance regulations. While public utility services provide basic markings, we specialize as experts in plant site locating and industrial environments where complex, undocumented private networks require professional verification.

Maintaining accurate, timely information on buried facilities is essential for any excavation. We utilize conventional electromagnetic detection for conductive pipes and tracer wires, alongside Ground Penetrating Radar (GPR) for plastic or concrete infrastructure. By combining electromagnetic and radar technologies, we identify and map both metallic and non-metallic utilities before you break ground.
For conductive utilities like steel mains or tracer wires, our technicians apply an electromagnetic signal to establish a high-confidence horizontal path. This process allows us to provide reliable depth estimates and clear surface markings, creating a roadmap for your excavation crew. It remains the primary method for tracing active utility networks across long distances or through congested corridors.
Where records are missing or infrastructure is made of PVC and concrete, we use Ground Penetrating Radar to fill the gaps. GPR is particularly effective for “blind sweeps,” as it detects physical changes in the soil rather than relying on an electrical signal. This ensures that abandoned lines or undocumented storage tanks are identified, protecting your team from the hazards of a utility strike in unmapped areas.
The free “One-Call” service only marks public utility lines up to the meter. It does not cover “private” lines, such as power to a shop, secondary gas lines, or internal plant networks. For these, a private line locating service is required.

Markings should generally be refreshed every 30 days. Weather and construction traffic can obscure paint and flags, so re-verifying the site ensures your team continues to work with visible, accurate safety data.
Yes. While extreme frost can slightly limit GPR depth, our electromagnetic tools work year-round. We use specialized paints and high-visibility flags designed to withstand Alberta’s winter environments.
Public services typically stop at the property line or meter. Private locating identifies the internal networks within your site, such as secondary power feeds, internal gas lines, and undocumented infrastructure.
Yes. We can survey our surface marks using GNSS equipment to create a digital map. This allows you to integrate buried facility locations directly into your CAD files for permanent record-keeping.
