Where technical expertise meets regulatory compliance
Sandborn Inspection Services is a dedicated business line providing floating roof inspections, LEL/LFL testing, seal gap measurements, and emergent repairs with qualified, experienced personnel, fully aligned with Canadian federal regulations (SOR-2025-88).
Every inspection unit carries emergency repair kits, enabling immediate minor repairs and ensuring regulatory compliance during the initial inspection.
With four decades of floating roof and seal expertise, we deliver concise, accurate, defensible inspections with detailed reporting to help operators maintain safe, compliant, and reliable tank operations.
Annual Open Top Inspections
Annual inspections remain a cornerstone of regulatory compliance for external floating roof tanks.
Sandborn Inspection Services performs:
-
Measurement of secondary rim seal gaps on external floating roof tanks
-
Inspection of pressure-vacuum vents to ensure proper operation and emissions control
These inspections help maintain seal integrity, monitor vapour containment performance, and identify developing issues before they escalate into compliance violations or operational downtime. All inspections are documented with clear reporting, photos, and actionable recommendations.
Monthly Inspections
Under current Canadian regulations, monthly inspections include:
-
LEL testing of Internal Floating Roof (IFR) tanks
-
Visual inspections of External Floating Roof (EFR) tanks
Monthly LEL measurements verify vapour space performance, while visual EFR inspections confirm roof condition, seal integrity, and overall operational safety.
Custom Inspections & Reporting
Every facility has unique needs. Sandborn Inspection Services offers:
-
Tailored inspection programs for IFR and EFR tanks
-
Custom reporting packages for regulatory submission, corporate governance, or internal compliance
-
Condition assessments, photo documentation, and trend tracking
-
Engineering-supported recommendations to address identified issues
Our custom inspections complement standard inspection programs and help operators manage risk efficiently.
Emergent Repairs
When inspections identify issues that require prompt attention, Sandborn Inspection Services can respond quickly with immediate emergent repair services. Our team is equipped to address problems such as seal adjustments, minor component replacements, and gap corrections directly in the field to help restore compliance and maintain safe tank operation. For larger issues that require more extensive work, we coordinate closely with the Sandborn Roofs & Seals installation teams to develop and execute a repair plan efficiently, minimizing downtime and operational disruption.
