Should I be worried?
I'm having my attached garage replaced. My house was built in 1921 and in 1938 an attached garage was added. Problem is it was too small to fit a car and the building was pulling away from the house because no concrete footers where used. Just wood on ground. Lots of dry and wet rot. In the end it was cheaper to replace the whole garage than repair it.
Problem - when excravating for the new foundation the excravator seems to have hit into my home's stone foundation (I didn't see him do it) and now there is a huge whole where the foundation once was. My foundation is a stone foundation (like cobblestone) with bluestone slabs over that. The contractor doesn't seemed to be concerned and neither did the building inspector who came to examine the first set of footings. The contractor has a wood form placed around the area and told me that the hole will be filled with concrete and the bluestone replaced over that.
Questions - doesn't concrete shrink? Shouldn't the wall be rebuilt with stone? I'm panicking here because this is near the area where my sewer line runs out ( a few feet away).
I didn't think to take pictures but will tomorrow. Anyone have any idea about this? Thanks for any info you can offer.
