Can you sue a previous homeowner for not disclosing damages or repairs that had been done?

I have lived in my house for 5 years in August 2009. I had an inspection done and it ped. There was a large crack in the exterior wall that had been repaired but they provided a report from a structural engineer that the foundation was ok. I have been having trouble with this side of my house since I moved in. The walls are cracking both inside and out. I have had two slab leaks. When remodeling the laundry they removed a wall and found plastic tubing all over in it that ran through the attic. Due to the vaulted ceiling the inspector may not have seen it when he inspected the attic. Anyhow, what it was was a slab leak repair. This was NOT disclosed in the Seller's Disclosure agreement. Also when they took up the linoleum in the bathroom and when I had a serious ant problem I was told that there was evidence of termites and treatment had been done. This was also not disclosed. I was VERY picky when buying this house and thought I hired the best of the best. If I would have known that there had been a slab leak I would have possible not bought the home. The people who owned the home before me were the only owners. They had the home built for them so they were the only ones who could have had these repairs done. What can I do?
