Home - Arbogast Mortar Analysis

The Old Capital, The University of Iowa
The importance of mortar analysis for the preservation of historic structures cannot be overstated. Failure to use the correct mortar can and, sadly, has caused irreversible damage to the surrounding building fabric. Masonry restoration, repointing (which is frequently also called tuckpointing), masonry crack repair, and/or other types of masonry repair, which includes such materials as limestone, granite, sandstone including brownstone, brick, terra cotta, chinking, stucco, rendering, and plaster all need mortar analysis. This means custom mortar matching to determine the composition of original (or historic) mortar.

David Arbogast, architectural conservator, provides scientific analysis of mortar for the restoration of historic structures ranging from state capitol buildings to log cabins.  The Old Capital of the University of Iowa in the photo is one of these structures. Working primarily with masonry contractors and architects, he provides prompt results even when work has already commenced. He is skilled and experienced in identifying lime, natural cement, and Portland cement contents in mortar and is able to make recommendations for the use of hydrated lime, lime putty, and Portland cement in replication mortar. When the job needs to be done the right way the first time contact Mr. Arbogast to receive excellent service at highly competitive prices.

Mr. Arbogast is also available for consulting regarding the use of water repellents for masonry. In addition, he provides historic masonry restoration consulting, for other masonry preservation issues such as building settlement, brick and stone consolidation, patching or replacement; masonry soiling and staining; mortar repair; and chimney repair.
