The dam has been declared a historic site so repair materials need to closely match the appearance of the original material. | | | Products:Belzona 4131 (Magma-Screed)
Belzona 4141 (Magma-Build)
Belzona 4911 (Magma TX Conditioner)
| | | Substrate:Concrete | | | Application Method:A temporary dyke was created around the area needing repair. Compressed air was used to blow the standing water off the damaged area. The surface was prepped with chisels and a bristle blaster. Dust and loose debris were blown off. The 4911 was applied and the repair was made with 4141 to just below the desired finish level. Finally a coat of 4131 was applied to finish the work . | | | Belzona Facts:Belzona was chosen because of its rapid cure, non-shrink and superior adherence characteristics. Magma build was chosen due to the need to work without forms and Magma Screed for color and finish. | | | Photographs Description1. Damaged area at waterline
