I am finishing by basement and noticed one of my support posts was coming out of the concrete floor at a terrible angle. I checked it with a level and sure enough it was way out of plum. This support post is one of two helping an I-beam that runs the entire length of my two story home. I decided I would fix this before it gets covered up by my remodeling. I can't imagine that an angled post is giving the best support to the I-beam. I broke out the concrete around the post and found a small plate (or lip you might say) on the bottom of the post and a large threaded bar leading out of the bottom and going straight down into the bed of gravel. (Because I only broke out around the post about 3 inches of concrete I can't really dig the gravel out to get a good look at what is below.) What am I looking at here? I was able to angle the post out from under the I-beam (must not be doing much) and tried to turn it to see if it would go up and down on this threaded bar. Nothing. I placed the post back in place. My question is am I going to be able to move this post over or not? Is it perhaps sunk into the footer even deeper than what I am seeing? or is it setting on top of a footer? What is the norm? Where can I see pictures of different styles of support posts so I can get a better idea of what is farther below and not visible to me at this time? Any help would be appreciated. By the way, my home is about 6 years old and I have nail pops all over the place. (We did suffer through the ice storm last Christmas that caused us to lose our heat for 5 days. Temp got down to about 40 degrees.) We have also noticed that the entire house slopes from the outer edge to the middle of the house. Not enough to effect doors or window but I can't keep my filing cabinet's doors closed.
