Welcome to our forum.
I moved into a new house, and need to get a pad setup before i buy my new tub(left old one at the old house). There is a pad allready in place, but it has a crack running thru it and part of it sank/tilted a few inches. The house is 14 years old, so i am assuming all the settling is done. I am wondering if it is possible to add an inch or two of fresh concrete on top of the pad to re-level it, or if i need to remove it and repour? Any suggestions are greatly appreciated.
