Full repointing with NHL 3.5 of a circa 1805 Pennsylvania stone farmhouse originally bedded and pointed with lime and sand mortar. The project included the removal of inappropriate Portland cement/sand mortar.
NHL 3.5 was used to repoint 9″ thick stone walls previously repointed with failed Portland lime/sand.
Reconstruction and restoration of 19th century historical building heavily damaged during 1994 Northridge Earthquake. Stone setting, pointing and plastering with NHL.
Lime applied over earth plaster over strawbale on exterior walls (similar to cob construction).
Fort point has stood guard at the narrows of the San Francisco Bay, underneath the Golden Gate Bridge for 150 years and has been called “one of the most perfect models of masonry in America”. Preservation and restoration work, previously done with inappropriate materials such as Portland cement, was failing and damaging the brick work, mainly due to the marine environment. Consequently, Saint Astier® Natural Hydraulic Lime’s NHL 3.5 was selected for the repointing of this monument, due to its resistance to salt and adverse weather conditions and its compatibility with brick.
