Completion of the Dickey Betts Fireplace and Chimney Project

Completed stone and brick masonry fireplace.  Three sizes of Tennessee Field Stone were used during construction.  We were trying to emulate an authentic, antiquated approach to masonry, and while considering how the material might have been acquired back in those 'horse drawn' days, it became apparent that there would be a variety sizes. Logistics just wouldn't have provided a single stone size without great cost, and a range of stone size allows a personality not afforded by such a contrived uniformity.  As land was cleared and farmed, top soil stones would have been piled along the sides of crop fields and pastures. These would then be utilized in the most efficient way which would have no doubt included a variety of shapes and sizes.  With this same mind set, we used the weathered face of the stone, rather than a broken face, allowing the dressings of time acquired by each individual stone to play a part in the aesthetic of the fireplace.  The result was a stoically beautiful centerpiece for the Betts Hunting Lodge.

All masonry requires extensive preparation.  Here we've laid the three different sizes of stone within specific rows so that each may be considered at a glance while looking for a particular stone shape.

Fitting the final pieces of a difficult puzzle.  A dry stack arch requires a great deal of patience and focus.  When building one of this size, you're constantly searching for the perfect fit.  A degree of mental stamina is necessary — many considerations take place before each stone is found.

Stone work progressing.

Interesting brick deterioration phenomena I came across in local town.  The mortars manufactured 100 years or so ago were generally inferior to that of today, and typically these low grade mortars decay quicker than the brick of the same era.  In this case however, the mortar is in tact, and the the bricks are all but gone in places.  There were small holes created by some kind of mite like insect, and I thought this may have played a part in the attrition, but as it turns out these are most likely incidental. The insects, being opportunist, probably burrowed into the faulty brick as they would the ground.  I contacted Bryan Light of the Brick Industry of America's Southeast Region and asked for his take on the matter:

Clay,

The photos depict the results of freeze thaw action on soft brick. Several things can cause this to take place.

1)      Reuse of brick that were lightly fired and never intended for use on exterior walls.
2)      Tuck-pointing older brickwork with a mortar that is too strong. The new mortar bonds well with the soft units, however mortar (as does concrete) shrinks a bit as it cures. As the mortar shrinks it pulls the faces of the brick ever so slightly, but enough for water to enter the units very easily. The increased amount of water now in the brick freezes/expands and spalls the bricks face off. This continues to occur every successive winter from then on.
3)      Coating the exterior wythe of brickwork, allowing that coating to deteriorate and trap moisture, rather than sheeting the water off the wall. Freezing does it’s work. It is sort of the same thing as allowing paint to scale or peel on wood siding. Soon the wood rots.
4)      Water at times enters the wall at a higher location than where the failure is occurring. Is there a parapet that is in bad shape above these photos?  

Whatever has happened, something has allowed excess water penetration into the wall. This is a water related problem. No way to stop it. A colorless coating might slow it down.
