A buried utility corrosion assessment evaluates how pipe materials, coatings, joints, soil, backfill, moisture, and installation details may be contributing to deterioration along an underground system.
Buried infrastructure does not experience one uniform environment. Trench backfill, native soil, imported fill, drainage, leaks, groundwater, coating damage, electrical continuity, and dissimilar-metal connections can create sharply different exposure along the same alignment.
Calicore combines field documentation with targeted resistivity and chemistry testing, material identification, coating observations, and records review to determine what evidence supports maintenance, repair, monitoring, or a more specialized investigation.
Step by step
How the process works
The exact scope is matched to the project, but a typical assignment follows these steps.
01
Review the alignment
We map materials, coatings, joints, repairs, failures, trench conditions, and known changes along the buried utility.
02
Select representative locations
Inspection, field measurement, and sampling points are chosen around changes in soil, backfill, drainage, failures, and construction details.
03
Document exposed conditions
When access or excavation is available, the pipe, coating, joints, depth, moisture, soil, and damage are recorded before repair or removal.
04
Set priorities
Locations are compared and ranked for repair, monitoring, replacement planning, or additional investigation.
Review criteria
What the utility owner needs from the assessment
Location-specific documentation is essential because one soil sample or one excavation rarely represents an entire alignment.
Station or mapped location and depth
Native soil versus backfill and observed moisture conditions
Pipe, coating, joint, and connection information
A clear explanation of how each observed location relates to the larger system

Frequently asked
Buried Utility Corrosion Assessments questions
Can one soil sample represent an entire pipeline?+
Rarely. Sampling and field measurement locations should reflect changes in alignment, soil, drainage, fill, depth, failure history, and construction details. The scope should match the decision and project scale.
Can the assessment include exposed pipe during a repair?+
Yes. A planned excavation can provide valuable access for coating observations, damage mapping, representative samples, and documentation before the pipe is repaired or removed.
