Bund Inspection, Assessment & Design
Specialists in bund inspection, bund assessment, bund design, and secondary containment engineering for COMAH and high‑risk industrial sites across the UK.
Bund Inspections & Condition Assessments
Arthian delivers full‑lifecycle bund inspection, bund condition assessment, bund design, and secondary containment engineering. With 30 years of experience, our civil, structural, and environmental specialists support:
- Bulk fuel storage operations
- Chemical manufacturing
- Food & drink
- Utilities
- COMAH‑regulated facilities
- High‑risk industrial sites
Our work aligns with CIRIA C736, CDOIF ERA, and UK secondary containment regulations.
Why Bund Integrity Matters
Ageing or poorly maintained bunds create significant operational and environmental risks, including:
- Non‑compliance with CIRIA C736 bund inspection requirements
- Failure to meet EA and SEPA bund regulations
- Loss of containment and pollution incidents
- MATTE‑level risks for COMAH sites
- Increased remediation and reputational costs
Regular bund inspections and engineering‑led maintenance ensure structural integrity, volumetric performance, and regulatory compliance.
Bund Inspection Services
Our bund inspection and bund survey services follow CIRIA C736 and HSE expectations for secondary containment.
Inspection Scope
- Structural inspection of bund walls, joints, penetrations
- Visual condition surveys
- Bund capacity calculation and volumetric modelling
- Drainage, low‑point, and water management checks
- Manual valve and outfall functionality
- Liner condition and permeability checks
- Bund leak detection and performance evaluation
- 3D scanning and digital topography for accurate assessment
- Prioritised maintenance recommendations
Bund Condition Assessments
Our bund condition assessments provide a clear understanding of structural integrity, compliance status, and required upgrades.
Includes:
- Risk scoring
- Failure mode identification
- Remediation recommendations
- Costed upgrade options
- Maintenance planning
This is ideal for COMAH bund inspection requirements and ageing infrastructure.
Bund Design & Engineering
Our civil, structural, and geotechnical engineers design new bunds and upgrade existing containment systems to meet site‑specific risks and regulatory expectations.
Design Capabilities
- New bund design
- Bund remediation and upgrade design
- Liner specification and bund lining
- Drainage and water control system design
- Construction support and QA
- Integration with tankage, ECI, and operational teams
All designs comply with CIRIA C736, CDOIF ERA, and UK secondary containment regulations.
Environmental Risk Assessment (ERA) & COMAH Support
Our environmental consultants specialise in CDOIF Environmental Risk Assessment (ERA) and support operators in demonstrating MATTE prevention and mitigation.
ERA Services
- CDOIF‑aligned Environmental Risk Assessments
- Integration of ERA findings into bund upgrade design
- Support for COMAH Safety Reports
- Site‑wide containment risk profiling
This ensures bunds are not only structurally sound but aligned with your environmental risk profile.
What Is CIRIA C736?
CIRIA C736: Containment Systems for the Prevention of Pollution is the UK’s most widely recognised guidance for secondary and tertiary containment. It applies to a broad range of sites—from small depots and warehouses to large petrochemical plants—and covers best practice guidance for businesses on preventing pollution incidents related to spills, fire, and floods, particularly for those storing hazardous substances. Our engineers are well versed in this for both the design of new bunds and the inspection, maintenance, extension, and upgrade of existing containment systems.
CIRIA C736 sets expectations for:
- Structural integrity and leak prevention
- Drainage and rainwater removal
- Capacity and volumetric performance
- Access, cleaning, and bund lining
- Inspection and maintenance regimes
Arthian’s engineers and consultants use CIRIA C736 as a foundation for every bund-related project, whether it involves design, audit, or remedial works.
