Settling jacks in log homes
Settling jacks in log homes
(OP)
I have a question about the use of settling jacks in a log home. One contractor is saying you need to adjust the jacks about every three months for the first few years. Another contractor says you can wait until the shrinkage of the logs is completed and then settle the jacks.
Is waiting until the settling is complete to adjust the jacks likely to cause structural damage?
Does anyone know about any written standards or instructions about how often to adjust the jacks?
Thanks,
Dave Adkins

If you are getting settlements in the order of 1/2" in 3 months, I would stay with the 3 mo scenario until the rate drops to 1/4", then increase to 6 months.
Make sure access to the jacks is unobstructed with sufficient clearance for the use of the jacking tools.

I would expect 4 to 8" of settling for a two-story structure.
