From Uncertainty to Verified Information

Investigate. Verify. Solve.

When records conflict, utilities are missing, or a critical crossing cannot be left to assumption, UII applies the right field methods to get closer to the truth underground.

Utility investigation and verification work

XYZ

Utility Verification

Confirm utility position, route, and depth using multiple technologies and field methods.

VAC

Vacuum Excavation

Nondestructively expose critical utilities and establish actual X, Y, and Z information.

Utility Investigations

Resolve unknown, missing, conflicting, abandoned, or undocumented infrastructure.

CAM

Robotic Camera Inspection

See inside sewer, storm, laterals, conduits, drainage systems, and underground piping.

H2O

Leak Detection

Locate suspected underground water leaks before exploratory excavation.

∆

Conflict Resolution

Reconcile discrepancies between drawings, 811 markings, private locates, GPR, and field conditions.
