117 S Water Street, Keokuk IO (Keokuk Union Station)
Scope of work:
Keokuk Union Depot is an historic train station on the west bank of the Mississippi River. It was built from 1890 to 1891, and since 2013 it is listed on the National Register of Historic Places. The Union Station has a Late Victorian style, Romanesque Revival, brick structure with sandstone trim. It features an asymmetrical elevation that includes a peaked roof in the middle and round-arched window and door openings.
Mortar decomposition had reached the point where brick and stone sill course were loose due to prolonged exposure to moisture. Efflorescence (white salt deposits) are significant contributors to mortar decomposition and acid etching away the surface of the stone and brick. This was neutralized. Non-matching bricks (color and composition) were replaced with matching salvaged solid historic brick. Also, we have rebuilt chimney’s 10 courses of brick.
