Stone Columns is about how this Architect clad existing slender p.t. wooden posts with native rock, for a bold, improved appearance. FINISHED STONE COLUMNS:
The Architect desired to help the owner obtain a bolder, more mountain-style appearance for this Cashiers, NC existing residence at the front door.
The Architect created this sketch to guide the Stone Masons in their work. Some dimensions were altered to suit the actual thickness of stone materials obtained, especially for the reveal and column capital.
FOOTING & LATH
The Architect also specified a special paint to help the p.t. wood resist being surrounded by rock and mortar for the next several decades. The Architect personally tested this paint underground in Florida for an 18 year period successfully, with no damage to the wood.
Due to the small job and existing finished site work (and desire by the Owner to not damage the existing premises), the Architect specified a Type S, pre-mixed high-strength mortar with all ingredients already mixed together in the bags, except for the water. Due to the cold temperatures during the rock work, the Architect specified cold weather precautions, such as using only 120*F hot water in the mix, to help keep the mortar from freezing during the nights of the work.
LOWER ROCK WORK & STRING LINES
Stone Masons used string lines to organize the corners of their stone columns and worked the stones to these strings, giving an orderly perfection to their work, and adhering to the Architect’s dimensions.
STONE MASON HAMMERING/FITTING ROCKS
The Stone Masons used special masonry hammers with sharp chisel edges to chip the edges of the rocks to conform to the shapes required for the design and to provide a more even and professional appearance to the rock work.
MID-HEIGHT STONE & STRINGS
Here, the stone columns have reached almost mid-height, carefully worked to the string lines to provide the Architect’s Craftsman Style “battered” (sloping) bases on the columns.
REVEAL & UPPER STRINGS
Here, the string line go vertical for the upper half of the stone columns. You can also see the 1″ inset for the stone reveal. This Architect provides some reveals to provide more order and design appeal to his stone columns, giving yet another depth of aesthetics to his artistry and mastery of his craft.
STONE COLUMN CAPITAL
Note that the masons inserted a small rock between the temporary tension string and the face of the keystone, to hold the keystone in place, before the mortar cured. Also note the material selection on the part of the Architect from a local rock yard, providing a carefully contrasting color and more consistent thickness for the triple stacked corbelled column capital.
COLD WEATHER PROTECTION
Architect specified additional cold weather protection of wrapping the stone columns with polyethylene during the nights, to help keep in the heat of hydration and warmer materials to keep from freezing during the colder nights.
