Third-Party Coating Inspection Services
Diversified Integrity Resources provides independent, AMPP (formerly NACE International / SSPC) Certified third-party coating inspections, coating consultations, and project management services.
AMPP-Certified Inspections
Our inspectors deliver objective oversight throughout surface preparation, application, and curing processes, verifying quality, safety, and long-term asset protection. Each certified inspector has completed the AMPP Coating Inspector Program (CIP) which includes Level 1, Level 2, and Level 3 certifications, covering inspection procedures, surface preparation, environmental monitoring, coating application, testing, and documentation to industry standards such as SSPC, ASTM, and ISO.
What is Industrial Coating Inspection?
Industrial coating inspection is a structured evaluation of protective coatings applied to industrial assets (such as steel structures, tanks, pipelines, and concrete surfaces). It confirms that the coating system meets the specified standards, was applied correctly, and is performing as intended. These coatings act as a key defence against corrosion, abrasion, chemical exposure and environmental damage.
Methods and Tools
During a DIR industrial coating inspection, several methods and tools are used: Visual inspection for defects such as blisters, runs, and pinholes. Dry film thickness (DFT) and wet film thickness (WFT) measurements. Holiday detection and surface profile measurement. Recording environmental conditions (temperature, humidity, dew point) and verifying correct surface preparation.
Inspection Frequency
A coating inspection should occur at key project milestones: before coating application (pre-inspection), during application (in-process), immediately after (post-application), and then periodically during service life. Additional inspections should be triggered by events like visible damage, unexpected environmental changes, asset modification or repair, or any indication of coating performance issues.
