I'm having my home foundation wall dug completely up to expose the wall because I'm having some "bowing" and "tipping" problems which have caused horizontal and vertical cracks in the interior wall. I was told in my contractor's proposal that every other cinder/concrete block would be filled with cement after the rebar is put in. The contractor said this would make 'columns' that would stabilize the wall and keep it from moving further. He also will waterproof the foundation wall and install a footer drain. My question is this: How do I know for certain that every other block will in fact be "filled completely" with concrete? I'm told the cement will be poured into every other block very wet so it can drain down to the footer. Am I out of line to ask for proof that the cement made in all the way to the bottom (the last block) and that the cavity is full of cement. I suggested putting a small hole in the bottom block so I could "see" the cement at the bottom. I'd also like for them to use a vibrator to make sure the cement goes to the bottom......like holding a chipper against the rebar for instance. Otherwise will it go all the way down and fill all of the hole that has rebar?
