Southern Water: Tank Lining

Southern Water commissioned us to apply a coating to a concrete plenum in a major water treatment works in the South East of England. The plenum was used in the process of deodorising waste gases generated by the water treatment process.


  • The floors and walls of the plenum were heavily coated with a residue left by the deodorising process.
Before treatment

Our Solution

As the floors and walls of the plenum were subjected to a residue created by the deodorising process, we cleaned the area manually and with an industrial vacuum. Once cleaned, we then applied a coat of primer and chemically resistant resin using our specialist spray machine.

After treatment



We completed the project in a single working day and the plenum was returned to active use one hour following treatment
