Belzona® Repair Makes A Rivetting Story



Buildings & Structures (BSTR)



Centrifugal Pumps (CEP)


Customer Location:

Oil Blender, Duisburg, North-Rhine Westphalia, Germany


Application Date:

June 1996


Application Situation:

Storage tank for petroleum fuels



Some of the riveted seams were leaking through blistering of the anti corrosive paint. If the blisters were pierced then the fuel oil would leak out. The tank was 14m diameter and 9.85m high.



Belzona® 1111 (Super Metal)

Belzona® 1321 (Ceramic S Metal)



steel plating


Application Method:

Works were carried out in accordance with Belzona Know-How System Leaflet TCC-1. The leaking areas were prepared initially by wet slurry blasting, as the potentially explosive oil would not permit gritblasting or grinding. Belzona® 1111 was applied followed by Belzona® 9341 (Reinforcement Tape). Two coats of Belzona® 1321 completed the application.


Belzona Facts:

Belzona repairs allowed tank to be safely re-instated without hot work and proved totally successful until the tank was eventually de-commissioned.
