Buildings & Structures (BSTR)



Roof Problem Areas (RPA)


Customer Location:

Software Distributor, UK


Application Date:

1990 & June 2005


Application Situation:

Steel corrugated pitched roof with large channel gutters running the length of the roof. The roof had several pipe penetrations, ventilation ducts and rooflight. The original roof was protected in 1990 by the local Authorized Contractor.



The original roof had been protected with Belzona® 3111 but new extension was suffering from leaks due to attack from bird litter and excrement which was chemically attacking the plastic coated steel sections. It is possible to see the corrosion on the extension, but not on the area that was originally coated with Belzona® 3111. Original application refurbished to provide further 15 years service life.

Belzona Facts:
