I posted a message about a month ago about our grout around our tile cracking . Which was just layed in the end of May . The contractor came back and took some grout out around a couple tile and put a additive to the grout , but it still is cracking . You can hear a slight creak in the floor , but it doesn't creak in the same place . We installed every thing ourselves except the tile . From talking to other people I feel we probably didn't have a solid enough floor . Sometimes I guess it doesn't pay to do some of the work your self . The tile is perfectly fine . Is there any way at all to take the tile up with out cracking it , so we can lay a stiffer floor . Any other advise would be GREATLY appreciated !! This has been a very expenive lesson to learn .Thank You !!!
