Case Studies

A major industrial facility required the refurbishment of three demineralised water treatment vessels after approximately 15 years of service. The existing rubber lining had reached the end of its operational life, exposing significant steel defects including corrosion, pitting, weld irregularities and surface imperfections that threatened long-term reliability.

Reevo provided independent QA/QC and technical assurance throughout the refurbishment, including:

• Steel condition assessments
• Surface preparation verification
• Monitoring of rubber lining installation
• Inspection of complex templating and nozzle detailing
• Verification of adhesive application and repairs
• Final QA/QC testing including thickness, hardness, adhesion and continuity testing.

The project involved extensive steel remediation, precision surface preparation, application of pre-vulcanised BIIR rubber lining, custom-engineered lining details for complex internal geometries, and rigorous quality inspections throughout every stage of the works.

• Three critical vessels successfully refurbished
• Long-term corrosion protection restored
• All QA/QC testing verified compliance with project specifications
• Complex internal geometries successfully lined
• Reduced maintenance risk and improved asset reliability

Independent inspection and verification ensured defects were identified early, repairs were completed to specification, and the vessels were returned to service with confidence in their long-term performance.

A large concrete processing vessel within a major mineral processing operation had reached the end of its service life after the existing internal lining system deteriorated. Extensive cracking, chemical attack and concrete degradation had compromised the asset, creating significant operational risk.


The refurbishment required complete removal of the failed lining, structural concrete repairs, installation of a bonded rubber lining system to the vessel walls, and a mechanically anchored geo-membrane floor system while maintaining strict quality assurance requirements.

Reevo provided independent technical quality assurance throughout the project, including:

• Inspection of substrate condition and repair requirements
• Verification of concrete repair quality and curing
• Surface preparation inspections
• Monitoring of environmental conditions
• Verification of epoxy filler and adhesive application
• Inspection of rubber lining installation
• Geo-membrane installation and mechanical sealing verification
• Final quality inspections before return to service

The refurbishment combined concrete rehabilitation, bonded bromobutyl rubber lining to the vessel walls, a mechanically anchored geo-membrane floor system, controlled environmental conditions during installation, and continuous quality inspections and defect rectification.

• Complete replacement of the failed lining system
• Enhanced long-term corrosion protection
• Verified compliance with project quality requirements
• Reduced future maintenance risk
• Increased confidence in asset reliability

Reevo's independent QA/QC oversight helped ensure workmanship met specification at every stage, reducing the likelihood of costly rework and extending the expected service life of this critical processing asset.
