Application Situation
Concrete wall of a Primary Settlement Tank (PST)
Application Method
Application was carried out in accordance with Belzona Know-How System Leaflet  FPA-1 & FPA-6. Once the surface was prepared, shuttering boards were fitted to the side walls to enable the Belzona® 4131 to be applied to accurate levels. Once the Belzona 4131 had cured the boards were removed and expansion joints cut into the repaired areas. These joints were then sealed with Belzona® 2211.
Belzona Facts
The Belzona solution was chosen due to the quick turnaround compared to other methods. Also the failure of the previous patch repairs led them to the need for a permanent repair. The longevity of the Belzona solution backed up by case histories supported the proposal.
