Iron Furnace – Lake Oswego, Oregon
The furnace was built by the Oregon Iron Company and began operations on August 24, 1867. After it was abandoned in 1885, the furnace’s masonry stack was left to endure the elements without any protection. Although the exterior of the 44-foot tall furnace is in relatively good condition, the interior stonework was seriously deteriorated. The work, done by Pioneer Waterproofing Company, consists of replacing the grout, repointing, as well as injection grouting with NHL mortars. Today, the stone furnace is the only surviving iron furnace west of the Rocky Mountains.
Taliesin East by Frank Lloyd Wright – Spring Green, Wisconsin
Taliesin refers both to the residence and the 800 acre estate surrounding it. First began by Mr. Wright in 1911, the house burned and was rebuilt twice.
Taliesin Preservation, Inc., is a private non-profit organization
working to preserve the buildings and provide public access and educational
opportunities. Their work on buildings with such a complex history- often representing multiple periods of construction, differing materials, and mixes, presents much fodder for philosophical and technical discussion…mortars and plasters
being a particularly rich field.
Taliesin Preservation has come to the conclusion that matching exact mortars is less important than coming up with the best technical mixes. They have been using NHL 3.5 for numerous re-pointing jobs and several plaster repairs both interior and exterior, and have been pleased with the results. Much of their upcoming masonry work consists of replacing inappropriate acrylic modified Portland based mortars with lime based mixes. It is a tedious but highly satisfying work.
