Application Situation

Sealing holes on the roof of an oil tank.

Application Method

This application was carried out in accordance with system leaflet TCC-02. Areas where the tank roof was leaking from were identified and taped out. Once taped out the surface was prepared using an MBX bristle blaster. Belzona 1161 was then used to fill in the leaks before Belzona 3111 was applied on top with a cut out strip of Belzona 9311 reinforcement sheet for added protection.

Belzona Facts

Previous welding had introduced heat activated zones into the tank roof resulting in weakness and corrosion at the weld seams. Welding the tank again would have created the same problems and that's why the Belzona cold applied solution was used.
