Friends of Fort Knox summer masonry restoration underway
The Friends of Fort Knox report that a significant masonry restoration project is currently underway at the National Historic Landmark that will target interior granite joints. Knox Masonry is focused on repointing the interior east facing granite wall that has a large amount of degraded mortar and vegetation growing between the mortar joints.
The Friends conferred with the Maine Bureau of Parks and Lands and Maine State Historic Preservation Office prior to beginning the project. Samples of the original mortar used in Fort construction were analyzed and upon recommendation from the State Historic Preservation Office, a natural cement mix was recommended, which mirrors what would have been used in the 19th Century. The mortar mix, Rosendale natural cement, is quite expensive — approximately $64 a bag.
The work is being undertaken by Knox Masonry, Bucksport, by mason David Leeman, who is certified by the Maine Historic Preservation Office in masonry restoration work. Earlier in the project, Leeman repaired two interior brick walls that were likely damaged by visitors kicking at the walls. The current masonry work is expected to continue into the fall.
Fort Knox is managed by the Friends of Fort Knox and owned by the Maine Department of Conservation’s Bureau of Parks and Lands.
