A driver plowed into our tree on our property. The crash literally caused the house to shake. This is where things become a little difficult. 15 years ago we repaired a crack in our basement foundation. This crack was in direct path of the tree/crash. For the past 15 years we had no problems whatsover, no further cracks, no leakage, nothing. A day after the accident I went down to the basement and heard a tinkle, as if water was coming in. The crack that was repaired 15 years ago had separated. Water is now leaking in our basement. IS IT POSSIBLE that this accident had anything to do with this? The insurance adjuster came yesterday and said well I don't think so because it was alreay repaired. Will need to have a structural engineer check it out. WHAT DO YOU THINK? IS IT POSSIBLE?
