This stone facade is coming to pieces on a well loved council building.
Either the council doesn't know how to fix it or if they do, they don't want
to spend the money.
One local I talked to said the water gets in behind the facade stone and if
it freezes it splits off the stone.
Here's a photo of it in the tinypic site:
Would anyone have suggestions on a cheapish solution if possible to fix the
The fault diagnosis is correct.
The cheapish repair is (impossible):
Repair and cracks, splits and defective and then give the wall at least two
coats of clear silicone liquid so that water runs off the stonework rather
than being absorbed into it.
The proper is (rather expensive):
But after looking at your picture, then it would appear that silicone would
be useless here, and major restoration works are needed - no wonder the
council doesn't want to spend the cash on it (they really do know how to fix
it *AND* what it would cost).
There is no "cheapish" fix. Depending on the age of the building, it looks
as though it is either limestone that's been cut and ground to give it its
shape and look (expensive) or cast stone, a manufactured concrete product.
In either case, replacement of the damaged stone would be less expensive
using "cast stone".
I'm sure there are restoration company's in your part of the world that
would be eager to give you or the council a price proposal to complete the
It is imperative that any restoration includes a means to get the water out
of the cavity between the veneer and the base wall as well as sealing the
surface from further water infiltration.
There is an old saying that "You can have it cheap, fast or good; you can
pick any two, three is not allowed or possible"
When I looked at that picture there seemed to me to be a number of
serious design flaws with the building, specifically with the
methodology for removing/draining water from the roof. Those scuppers
(one right above a door way!) simply pour water down the side of the
building! Look at the stains on the section to the right of the
windows, left of the doorway-entry.
I personally would run like hell if someone asked me to do
repairs--until the basic flaws are resolved, I don't think any repairs
of the facade will be successful.
I don't believe those are scuppers. Look again. I think they're
meant as some sort of crenallation. The upper wall is capped with a
piece of stone and the lower section of wall, which kind of looks like
a scupper, is also capped with that same stone, just in much more
deteriorated condition. The left hand low section doesn't have a dark
stain directly under it. The stain is well off to the side, and
wouldn't the spalled lower cap stone also be stained from the water
running over it?
The stain off to the left is from the water running down the pitched
flat stone cap on that gable end wall. Most likely the leak is caused
by poor detailing where the lower wall section cap stone meets the
decorative stone veneer. Whatever is done with the veneer and
lettering, those capstones should be pulled and reset after a proper
waterproofing job is done.

I guess either a better set of images, or an inspection would be
necessary to figure out what's up there. Clearly, it seems, there is
excessive moisture flowing down the face of the building, and poor
construction techniques. The image I'd like to see would be from above
where the roof meets that front wall. I wonder if there is a gutter
behind the wall, and it is malfunctioning?
Peter, I agree. It looks like there may be a parapet type
situation. The stone has been saturated and frozen. I suspect
the moisture is getting into the stone from behind or above inside
the wall. The water and damage do not appear to be cascading down
the front face, or the rest of the wall would have similar
It is going to be expensive to do a high quality restoration of
the lettering and decorative work. I think it is limestone. Some
nice work can be done with epoxies, etc short of removing and
Keep the whole world singing . . . .
Concrete surface that stones are attached needs a thorough going over......
Yes, scuppers are flawed design....Need to extend out beyond wall.
Metal and or stainless steel pins for new facade.....Like dental work.
Mechanical attachment and mortar. (bone surgery)
Epoxy based mortar mix....
They dont want to spend money?
There is no fix with no money.
A cheapish solution is the problem, just by that small section I bet
no care has been taken on that building and the stone, and that wall
has been deteriorating for maybe 10-20 years, Cheap, yea stay cheap it
will eventualy all fall. The water is getting behind the stone, as in
roofing , tuckpointing is bad, I bet no maintenance has been done,
because Cheap is the objective you have. That could be a 10-50,000$
repair, because they were cheap.
