Problem: 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.
