I took pictures of a huge retaining wall (two years ago) that was obviously failing. They simply parge coated the failing openings (cavities) of this wall with fresh mortar and I guess they thought that they performed a fantastic repair.
Take a look at this awesome patch job two years ago…
This is one end…
There’s a magic that folks believe in. That somehow if they ignore a problem it will heal itself. Nobody believes things will ever fail until they do. Then they look for somebody to blame.
Pretty clear that who ever filled those cracks in the retaining wall(I hate to call it a repair) either had no idea of the physics and forces involved or just did not care.
Can’t you just hear someone saying “It only a little dirt, that’ll hold it”
