Sandstone Structure Refurbishment and Modification
The Problem
A 2-½ story 1904 Vintage Sandstone Farmhouse was purchased as part of a cattle ranch.
Renovation plans of the 2-wythe, rubble foundation gravity structure included enlarging
windows, stabilizing the battered foundation, removing portions of load bearing
walls and repointing mortar joints.
The Solution
The small foundation stones were stabilized using a “sister” footing system constructed
of dowels and reinforced concrete. Larger window lentils were installed using opposing
steel angles installed one wythe at a time and bolted together. The lower half of
a bearing wall was removed using the window enlarging technique; installing the
header beam first and steel support columns second. Removal of the old lime based
pointing mortar and repointing with masonry cement and sand completed the project.
