I am a homeowner considering having porcelain tile installed over a 600sqft concrete slab on my patio (around 30 yrs old or so).
My main concern is that the slab is divided into 4 sections by bricks, which create big joint lines (please see the pics for more detail). Although there are no apparent cracks (except for a thin one), I am afraid to tile on top of it all to find out a year or so later that there is floor movement and ruin my tiles.
I have been told that it was not a problem at all, that it is a big concern, I have heard about "Schluter®-DITRA", I have been told about "adding a membrane on top of the joints", so at this point I am confused as to which way to go (or not go).
I am considering having the concrete stamped instead (I had it done in my driveway 3 years ago and it still looks good) but I would rather go with the tiles if safe.
Thank you for any gidance you can share.
