Application Situation
The area of repair of the dam structure was below a bridge and would be difficult for welding. Belzona was chosen as a safer and time efficient option with protection for a better longevity in mind.
Application Method
Existing structure and plate was blasted to SSPC SP10 standard of cleanliness. Belzona 1121 was applied on both the structure and the plate for a wet on wet application. Due to freezing conditions, heater were put on to enable proper curing at favourable conditions. Belzona 5811 was then applied to seal the perimeter around the bonding area. Necessary inspections were carried out after few weeks and application was certified okay.
Belzona Facts
Belzona was not only a cheaper option considering the application area and conditions, but was also efficient and protective of the structure.
