I guess I'd ask first where the gap came from -- is it a development or
an expansion joint that lost it's filler or just a space between two
If it's a crack that grew w/ time, likely there's not much point in
anything unless stabilize the wall first as it won't stay put long anyway.
Assuming it's stable, it'll need some backer filler material and then
there are several choices for a caulk or filler, depending on the
situation, including mostly pointing (or repointing) instead.
1. Is this repair cosmetic (only for appearance) or must the filling
carry more than its own weight?
2. Indoors or outdoors?
3. Expected range of temperatures (winter and summer.)
4. Depth (e.g. one inch or six?)
We can imagine successfully stuffing the gap with cement,
invisibly held in place by some non-rusting material if necessary:
but an outdoor repair exposed to rain and extreme temperatures
might need the attention of an experienced stonemason.
alot. i know the best way would be to replace the section that is
pulling away. the part that is pulling away is part of a 90 degree
(forms a corner)wall...if the homeowner does not want to replace the
section in question i am now thinking of securing the corner with
threaded rod and sika anchor fix so that would at least (hopefully)
prevent the wall from pulling away more. the wall is about 3 and a half
to four foot tall with the crack(gap)extending all the way top to
bottom. after securing the wall i will fill the gap with an appropriate
mason chaulk...should work
I seriously doubt it will (work, that is) for any extended time, anyways
unless do something about either the foundation or add lateral support
along the length of the failing section besides at the corner.
All that will do is constrain the corner and the rest will continue to
fail and cause another break a short distance away from the existing
I know that's not what you or the homeowner want to hear, but I'd be
pretty confident it's what a mason or structural guy would tell you if
asked to evaluate...
