Officers' Club, Presidio of San Francisco
San Francisco, California

The Officers' Club is one of San Francisco's oldest buildings and was part of the original Spanish Presidio constructed in the late eighteenth century. It is undergoing a comprehensive historic rehabilitation that will return the beloved icon to its former grandeur. Saint-Astier NHL mortars are used for stone setting as well as plastering on the original adobe walls.

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.
