Hello. We have an old log cabin that's in need of repair. Under three of its corners, the cabin sits on huge concrete piers that go below the frost line, but on the fourth corner, it's only sitting on a stack of large rocks. This corner has settled a bit, and I'm planning on jacking it up a few inches and pouring a large concrete pier to support it. Can the force of jacking up the cabin potentially damage the chinking? Are there any precautions I should take or steps I can take to make this less likely? Any suggestions would be appreciated.
