Our team provides complete private utility locating for residential, commercial, and industrial projects across Ontario. Using advanced electromagnetic (EM) and ground-penetrating radar (GPR) technology, we accurately detect and mark:
Buried utilities: gas, hydro, water, and communication lines
Private infrastructure: sewer laterals, irrigation, and electrical conduits
Unknown subsurface objects: tanks, rebar, and voids under concrete
Pre-excavation verification: confirm service depth and direction before you dig
Each locate includes clear on-site markings and a digital report to keep your project safe, compliant, and on schedule.

Customer Feedback
Trusted by Ontario Builders and Contractors
We’ve supported hundreds of construction, engineering, and municipal projects with accurate subsurface data and rapid response times.
“I called in for a basic scan of concrete to identify power in the slab. Before they left site, they had put a camera down the drain, confirmed the exact location & depth of my tie in spot, radio scanned for high voltage conduits & performed a GPR scan to identify any additional obstructions that the radio scan was unable to see. From the variety of tools on every truck, to the experience of their scanners, this company is in a league of their own”
