Belzona® 9331 (Reinforcing sheet) | | | Substrate:Galvanized steel | | | Application Method:Belzona® 5811 and Belzona® 9331 were applied in accordance with a modified Belzona Know-How System Leaflet VPF-2. | | | Belzona Facts:Replacement of the damaged pipe would have cost $700,000 and taken considerable time to complete.
