Hi diy, I posted this before in /adv/ >>>/adv/32636875 and someone there gave me a tip to search for tutorials and post here, here's the issue:>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.Some anon told me it was due "expansion" and that's something new to me (I'm really ignorant about construction and haven't tried reparing stuff before). I'm not sure which kind of tutorial would be good for something like this, and I have seen some just using some tube thing with some glue like stuff, and I wonder where should I actually start, for example, I don't know if it'd be the best to remove just the loose tiles, or somehow try to remove every tile to "make it all over again".
>>2891588I forgot to tell this, which may be relevant, the place has a cement floor, and the tiles over it (I guess it may be different between cement or wood or whatever the floor beneath may be made of).
>>2891588They popped out because they were installed wrong and there's humidity coming from your foundation. there's no easy way to fix this
>>2891593Thanks for answeringI suspect that's the case, there's humidity coming from the walls whenever it rains (at least it doesn't come into the house, it used to be united to another buiding, but the owner decided to separate it, but the ones who put the wall may have done it wrong because a waterfall forms on the other side whenever it rains.So, now I know it won't be easy but... Are there any chances I may be able to fix it without knowing a thing about construction?I guess I also have the option of "removing the tiles and leaving them aside" if it's way too much, and somehow search for "professional help", but from what I heard, most of the local people working in this kind of stuff, do it wrong (like in this case), and I'm worried this may repeat soon, so I want to know which knowledge I may need before doing anything so I start cramming it up to try to fix this.
>>2891596maybe try and get the water away from the building - eavestrough, a bit of grading etc...
>>2891598there's not actual water coming inside, or in that part (as far as I know, it was fixed somehow because some dentist rented the place so it got fixed because it was an issue), but maybe it was already there since long ago. It has been kind of cold these days, and I'm not sure if that may be related to what happened. I'll try to get some tools recommended in the other post ( hammer and a wide chisel) and try to remove whatever I can (not all the tiles moved). I'll try to update my progress if this thread is still alive after I try that.
Looks like the perimeter expanded (wood?) and it got warmer causing the tiles to expand too.Needs an expansion gap between the edge and the tiles at a minimum.Also, you could use caulking instead of grout, possibly every second or third course to act as an expansion joint.
