Case Study - Fire Sprinkler Water Tanks

Client: Global Technology and Domestic Goods Manufacturer

Project Brief: The Internal and External Relining of 1 No. Steel Cylindrical Fire ‘Sprinkler’ Tank.

System Specification: Solvent Free Polyurethane

Completion Date: 21st January 2009

COVAC Contract Ref: 798

Summary of works

1 No. Steel, cylindrical water retaining structure, sized at approximately 14.7m dia x 6m high, which had been internally painted with a Bitumen based substance, which had reached the end of its useful life due to sub-film corrosion, low film build, poor elongation properties and general deterioration.
