Private Utility Locates – Expert Underground Public & Private Utility Detection in Washington

CNI Locates offers comprehensive private utility locating services throughout Washington State (including Everett, Renton, Seattle, and Tacoma). This service identifies and marks both public utilities (typically covered by 811) and privately owned underground utilities that conventional public locates often miss. Using advanced detection technology such as electromagnetic locating methods, ground penetrating radar (GPR), passive and active signal tracing, and depth assessments, CNI Locates helps contractors, engineers, property owners, and project planners locate buried pipes, wires, cables, and other subsurface features with precision. The process includes marking utilities on the ground and collecting data that can be used for preplanning, as‑built documentation, and integration into CAD or GIS systems, making subsurface work safer and more efficient.
