Private utility locating services will mark out all existing utilities, not just public lines. Private locating is helpful if you need to update existing plans, uncover unknown utilities and structures, or are working in an area where public locator services won't touch.
One Call is a great option if your project site only needs public utilities marked. However, if your maps show secondary utilities or private lines, Trinity Subsurface is the company to call! We mark all utilities, public and private with precision. In addition, we require multiple locate methods to complete a thorough mark out. After detecting utilities with non-destructive testing, we can also use vacuum excavation to confirm the exact location, depth and other material characteristics.
