Hi /adv/ let me tell you some background info first:I live in this place which was a warehouse of my relative, he moved out of the city so he let me stay here for free, and gave me freedom to break/repair stuff.The place is made of bricks and cement, and I got people to make some basic living stuff (some water connection service and electricity stuff), it was cheaper than paying rent somewhere else (and this place is near my current job). Recently some tiles suddenly started popping out violently (like if some giant worm was walking under the earth), and I'm not sure what should I do. This doesn't seem to be the first time this happens (there were some broken tiles in the attic), and I'm not sure if I should just let them be or what. I asked before and it seems they have been there for like 30 years, but there are other tiles in the restroom which haven't popped out at all, so I guess there was some "bad quality work" there or something (I'm not sure anyways, I don't know stuff about construction). What would be the best course of action to do here? I'm not sure if I should try to remove the pyramids formed by the tiles. I can clearly see the cement under them now.I got this image from the web, but it kinda looks like what happened.
>>32636875If that is pic related the installer didn't put any expansion joints down. So in a shower you just use caulk in the corners and edges and that allows expansion, but the larger the distance the more room you need. This of course depends on the subfloor(wood, concrete, etc) since wood will expand more.Here is what you do if it's half as bad as your pic.You need a hammer, chisel(wide), and some energy. Before using either get out a screwdriver or thin tool, and pry up the bad tiles. Ones that are full, stash away and try and clean the thinset off them with soapy water(hot).IDK if that will work. If it doesn't just toss them.With the rest of the tiles remove them in full sections if they are loose.After build in some expansion for the tiles via larger grout joints. if they are 1/4in normally do 3/8. Of course you will need thinset and a bucket/container to mix. add water to the container, then add thinset/mortar mix. For flooring it's fine if it's a little soupy, but you want it peanut butter texture, then use the notch trowel to lay down lines evenly, then stick the tile on.Of course you will need to grout it back over the tile later(next day).use knee pads or a towel to protect your knees.To cut the tile you can use a rented manual tile cutter. Works good for square/rectangular tiles.Watch youtube videos. Fixing this type of shit is easy if you aren't omega dyel/poor.
>>32636993Thanks a lot, I'm not sure why I didn't think about searching for youtube tutorials, there are many terms I didn't understand from your message (I have no idea what this "expansion" means, for example).Thanks a lot, I'll search for some tutorials of tile repairs then.

>>32637072expansion is the tiles "moving" sideways, hitting each other, and going up because the floor beneath it is moving. That's why you get the coloumn of tiles in the OP pic "tenting". The floor is contracting inwards and the tile have no where to go but up.godspeed, and as the other anon said post in/diy/ for more pro help. I have just done a couple tile jobs and youtube tutorial maxx
>>32637396>>32637084Thank you again, I'll make a post there too
