Noticed 5 areas on one side of the house that were bulging through the siding, all at the same level. I felt underneath one of the bulges and felt something solid underneath the wall sheathing. This was a pier and beam concrete foundation with rim joists and cross joists built on top. These bulges were at the base of the structural wall above the rim joists (it appeared the bottom of the wall studs were kicking out). There was no access to the crawlspace and visual access was limited from the crawlspace vents. In the picture you can see the shadow underneath the siding (below the arrow) where the wall was protruding. Does anyone have any ideas what this may be?
What picture?
