Stone church 'shedding'
"A late 19th Century church in my area is shedding flakes of stone from
the
outside surface of it's walls. Some of the flakes are as thick as 2" at
their
thickest, and most taper off on the edges.
I'm wondering if this was caused by some kind of fractures or weaknesses
imparted to the stones during the original cutting."
Is this a new circumstance, or has it been happening for many years?
Spawling of this nature usually has to do with moisture and freeze-thaw
cycles. A few questions?
Where is the church? what type of stone is it constructed of? Can you
tell me any thing about the stone bedding orientation in the wall? Is the
spawling occuring in any particular area, or throughout the entire wall?
Most important, has the building been recently worked on. By this I mean
re-pointed or possible had a sealer of any sort put on the stone, or
renovations to the interior side of the wall?
Lots of questions, few answers.
