We purchased a home two years ago that had a cinder block foundation. When we looked at the house we noticed there were about four or five cinder blocks pushed out in one corner of the basement and so before purchasing the home had the foundation evaluated by a structural engineer. We also followed up with the home owners who informed us piers were placed in the basement to support the corner of the basement where the cinder blocks had moved. The structural engineer we hired assessed the basement and did not believe there was anything wrong with the basement. He thought the repairs adequately fixed the settling problems. A year went by and we had no problems. At about 1.5 years some slight step-wise cracking started and the cinder blocks moved an additional 1/8.” At two years we now have ¼” crack down the middle of one cinder block, stepwise cracks 1/8’’ and additional cinder blocks have pushed out. We have cracks in the floor in that corner and the corner now appears pitched downward as if the corner of the basement is sinking. The basement piers are under warranty. The company is recommending that the cracks be filled and that additional piers be placed on the outside wall. Is this adequate? Or should I be asking for the corner/wall to be replaced? Is that even possible to replace part of a cinder block foundation?
