Client: Cheese Factory
Project Brief: The Internal Preparation and Relining of 1 No. Steel Truff Tank
System Specification: Acothane DW Solvent Free Polyurethane
Completion Date: 2011
Guarantee: 15 Years
COVAC Contract Ref: 1049

Summary Of Works

1 No. Truff Tank sized at approximately 10m x 10m x 5m high. This tank also has an internal, steel, divisional wall, effectively, splitting the tank into 2 No. compartments, each sized at approximately 10m x 5m x 5m.

The internal surfaces of the tank had been previously painted with non (WRAS / DWI) approved Bitumen which had approached the end of its useful life, due to sub-film corrosion, non conformity and general deterioration. If left untreated, the internal surfaces would continue to be at risk from bacterial growth including Legionella, Pseudomonas and Biofilm; this can lead to further deterioration in the tank’s surface structure and contamination of the down services with the supply of unhygienic water to the outlets. The tank was relined by COVAC with a coating approved for use with drinking water and a 15 year guarantee was given to the Client.
