Location Location location .
....nope but its real near me
...but meet me at 4 corners Ariz. with the other half of the Jello box.and
I'll tell
.Ive taken the column down already and awaiting soil stabilization .
...Meanwhile another stump the chumps
Large Ohio sandstone church 1870(English country Gothic) Dimensional stone
(3 sides
have sq planes)
Very finely bedded Joints 3/8 - 1/8
brick back up at interior
Original mortar... Lime putty
1967 Repointing with Portland mix
Water has gotten behind stone from leaks in gutters
also Heavy foliage, and improper landscaping causing continual
wetness-allowing no drying cycle
conditions
Joints too hard causing the "free"stone to delimitate (shear) at bedding
plane
Note: free stone is called such because it is difficult to tell where the
bedding plane is
Water is also causing the skin to weaken and pop in cold weather; and hot sun
Portland pointing did not allow the water to weep properly
also had no "give" causing the arris to split
Some areas of continuos wetness has caused the stone to loose some of its
cementatious quality, appearing dull grey and flaky from orginal hard with
warm buff color
Orginal bed joints now 60% washed out (dust ) leaving voids behind portland
The question without much fanfare
is how to proceed on the voids
use 00 sand does one
A. Repoint 1-1-6 with backer rod without backer rod
B Re point lime putty (complex lime mortar)
C. grout with lime and caseine at 3 ft intervals going up the wall using pig
tails
after grout stabilizes repoint portland with putty.
Remember there are now wrong answers only better solutions
.........and there is only one idiot among us ..and thats the village idiot
or me for asking these menu questions...Best Michael
