Hi all - I've been lurking here a bit since buying my first home at the end of April and am moving full steam ahead with all of the projects I have to do. The next (and last!) major project is flooring. We had wanted to put porcelain tile down in each bath (there are 2) and the kitchen but I've hit a snag.
When I removed the existing flooring in bath #1, I noticed a patch job in the concrete slab foundation. It looks like they had to get in to the foundation, possibly to fix some plumbing issue at some point (I'm not sure exactly). So aside from the patch job, there's a good sized crack as well. Here are pictures of what I found:
So - I filled the crack and now it looks like this:
Above you can see the 'patch job' that was done previously.
The area where you can see the patch job is somewhat uneven so regardless of what I put down I'll have to level the floor a bit (my project tonight). The crack SEEMS to be the result of whatever work was done when the patch was created but it still have me nervous if I were to lay down tile.
Is what you see here enough reason to scrap the idea of putting tile down and go with another flooring product or does it not seem too risky if I make sure everything is flat and I use a membrane over the cracked area (3 times the width of the tile, of course)?
You can see the glue on the concrete from something they had there before, but the concrete itself is quite rough so I'm thinking that I don't have to sand that off before using the self leveler tonight.
Thanks in advance for the advice - I greatly appreciate it. In related news, that bath is off of the kitchen and the patch job extends in to the kitchen a bit, so I've decided to put a floating floor in the kitchen.
