Hi everyone! This is my first post so I hope I do this right! We are having a sunroom put on our house by a major well known contractor. However sub contractors......we need to know proper way to put in supporting columns
By plans they put 3 ft deep cement columns into ground with pressure posts slightly into..
(during rainy day). A week later started to sink 2 weeks more about 1 1 /2 inches and all dirt around gone
What is proper way to raise sunroom posts?
Ps sunroom is off level now and windows and doors do not close properly. Inspector said tell contractors to raise posts. But I want them to do it properly!
It sounds like the pier's were installed in the ground that did not have proper compaction. Your compaction should be 95% of existing soils. They should have used an embedded post connector in the pier. You say that the pier or footing was about 3'. What was the diameter and the depth.
either that or per the building code should have extended to undisturbed soil having the proper soil bearing capacity for the load imposed by the column. 36" may have been the minimum depth for frost protection, you have to go the deeper of the two.
when a few photos are posted we'll have a better idea.
It happens all the time (even to me in the past ), all the disturbed soil has to be removed from the hole, and they have to be tamped before pouring or they WILL settle. Not sure how to deal with it now, but this is typically a good place to use NS grout between the pier & base plate........
