Tiling over cracked loose tiles
 
I am a new subscriber and recently bought a pier and beam house with loose, broken and cracked ceramic tile in kitchen, bath, and mudroom (a continual run). A very inexpensive fixer-upper, the inspector said house is now sound, but I still don't trust the structure not to shift again. It does appear to be structure related as evidenced by cracks around windows ect. Neighbors cautioned me that with our soil, I should not re-install ceramic tile as it would likely break again. So my questions are;
1) Should I install high quality vinyl type tile now instead of ceramic? Or could I possibly install porcelain tile now with proper underlayment?
2) Is there anyway I can install over damaged existing ceramic tile? Or over previously trowled stuff left under it? Or should I try to remove that hard gunk too?
3) What about Anti-Fracture Membrane, Crack Isolation Membrane or Crack Suppression products as underlayment.... for ceramic, vinyl or neither?
Sorry this is so long but wanted to give you as much info as possible on my situation for your consideration.
And cost is a factor. I am a financially struggling yet pretty handy single mom!

If the tiles cracking there is always a reason for it.
Poor subflooring, shifting foundation, rising moisture from the area below.
No telling from here.
I do not see tile in your future unless there's lots of prep work done before.

From what you describe, I would stay away from any ceramic or porcelain tile. Like Joe said, it's just gonna crack again without some major prep work.
I suspect deflection is your main problem. Movement or bounce in the floor will cause any ceramic or porcelain tile to crack and fail.
If you're on a tight budget, I'd pull it all out (don't go over broken tile) and look into sheet vinyl.

Did you happen to look at the condition of the pier and beams under the home?

Example:

Just because your not cracking In sheetrock doesn't mean good news.

Also could be sloppy tile job, wrong grout and or morter, subfloor might be all wrong.

Thanks for your replies. The inspector said the piers and beams were right. But I agree with ya'll. No more ceramic or porcelain. What about the troweled cement like stuff under the tiles? Does that have to come up too? Or can I level it or put backer board over it?

Backerboard is for tile only you won't get the morter to be smooth enough to put vinyl over do u know how much subfloor you have from joists to below morter?

Pull up a tile or two and see what you have under it-----My guess is it was a bad install over plywood.

Most should scrape off with hand tools.

Say what?!? LOL! Oh I know this is serious, but you lost me there. Would you explain to a newbie please? How do I figure this? Thanks.

Oh Mike,
That's what the inspector said, a bad install BUT there is the verticle cracking around the windows and interior doors stick and are hard to force open or closed. I will pry some up and chip away the adhesive stuff and check. Will report back.

Lol the joists are the beams that hold your sub floor up sub floor is usually 3/4" of ply maybe another layer of ply or cement board on top of 3/4" ply.
