Structurally dangerous pipebridge restored to ‘as new’ condition.
Water & waste industry
Scope Of Work
A full structural survey was carried out, revealing that
extensive repair work was required. Corrocoat carried
out this repair schedule, and fully corrosion protected
the bridge to ensure extended maintenance free life for
Corrocoat’s POLYGLASS, PLASMET ZF and PLASMET ZX.
• Grit blast to IS0 8501-1 cleanliness standard SA 21/2.
• All joints encapsulated using Corrocoat’s Polyglass
• Total structure and externals of the pipe were treated
to two coats of Plasmet ZF and a top coat of Plasmet
In 1999 Corrocoat went back to the pipe-bridge to
ascertain the success of the refurbishment work and
assess the performance of the coating systems.
The coating was still in excellent condition ensuring the
bridge will remain structurally sound for many years.
