Tiles on the bathroom wall keep cracking
K
last year
Hi
We updated our spare bathroom in Feburary. We love the result, but tiles on the wall keep cracking. First, my husband found a hairline cracks on two tiles so we called a contractor and he fixed it. A couple weeks after, I found similar crack right next to the tiles he fixed. This has been happing only around the same spot. Also the grout is cracking there for some reason.
We asked the contractor why this has been happing but he is not sure...
In the same bathroom, sometimes the door dosen't close smoothly although it was replaced when we updated the bathroom. But sometimes it closes fine. The same thing also happens to our master bathroom so my husband thinks our house constantly moving. But how??
I'm assuming something was not installed right underneath.
I'll highly appreciate your thought. Thank you!
This is what my husband found first.
Cracked grout
Before tiles were installed.

Oh NO! Why me? New bathroom wall 'settled' (?) and tile cracked!
Comments (23)I thought you were in MA, not ME. The good news is that if it's the PT that shrank, it's done. The bad news is that if the soil is undergoing expansions and contraction cycles...it's unstable. I don't have a vast amount of experience working in clay, but I had a big bucks job in clay years ago. We actually set up something similar to a drip irrigation system around the perimeter of the foundation. The purpose was that the drip irrigation would keep the clay continually moist so it wouldn't undergo movement cycles as the clay dried and rewet. It'd essentially stay permanently wet and not move. Any excess moisture was removed by foundation perimeter and footing drains. Now, you wrote that the crawl space is sealed up... 1) For clarification, I'm assuming that there is a concrete foundation around the perimeter of this addition? Or is it built on piers? 2) If it's a poured foundation, was a rat slab (thin 2" poured slab) or a full slab poured in the crawl space? Or is the bottom of the subfloor open to soil on the ground? 3) With the clay, did your dad have any engineering analysis done with regards to soil movement or stabilization? As to "what now"...was this a Kerdi shower? Or did it have a topical membrane (HydroBan, RedGard, etc)? I remember your shower but forget the specifics of how it was built. If Kerdi, the cracks are sort of inconsequential when it comes to water penetrating into the walls. The cracks are more cosmetic unless they really open up. I'd get in touch with your installer regarding the details of the walls. Depending on how the walls were detailed/waterproofed might give you a warm fuzzy regarding letting things sit as they are while you see if movement has stabilized versus taking action (caulk the crack, etc) if water penetration may be a concern. I'd mark the ends of the cracks with blue tape and keep an eye to see if the cracks extend or if the movement has stopped or stabilized....See MoreHelp Please-grout cracking/tile separating in new bathroom
Comments (9)Curb movement like that is typically from a wood-built curb (stacked 2-by lumber, for example) that is absorbing moisture and expanding/swelling. How is moisture getting to the curb? Could be one of several things. Not sure how conscientious the installer was in terms of making sure the shower pan membrane is sloped (versus laying the membrane flat on a flat subfloor), or how he detailed the membrane over the curb. It's possible there are nails through the top or inside faces of the curb (and thus through the membrane) and moisture is getting through the nail holes. It's possible that he built you a perfect curb but used wet pressure-treated wood and the PT wood is warping as it dries. Or your house is on a slab, and he put the wood right on the slab. Moisture through the slab is causing the wood curb to expand. So it could be one of several things. It should be fairly easy to diagnose though, as the tiles are popping off on the outside face of the curb. They'll have to be removed eventually to diagnose and repair. When they are removed, take a look to see what's in there. Post photos if you can. To give you a bit of an education as to how a typical CPE-membraned shower with a wood curb is built, check out Harry's pictorial. Note that Harry's membrane is "draped" over the wood curb. That there are no nails/screws on the top or inside face of the curb. That the lathe (wire mesh) is bent in a "U" shape and it's simply the inverted "U" bends that hold it over the curb. Again, there are no fasteners through the lathe and into the top or inside face of the curb. I have seen instances where the membrane gets draped over the wood curb, then the installer nails cement board on the three faces of the curb and tiles on the cement board. Not good. Again, nails through the membrane on the top and inside face are a no-no. I don't see screws through the bottom track of your door frame that go into the curb. That's good.

Comments (14)If I "ignore" the issue, and just caulk over the crack, what's the worst that could happen? Second worst: Water leaks behind the caulk, destroys the studs behind the tile and the joists in the floor, and you have to rip out the whole shower stall, wall and floor and replace everything. And do mold remediation. Worst: Water leaks in there, destroys the studs behind the tile and the joists in the floor, and you step in the shower one morning and the joists give way and you and the shower stall end up in the basement. No fooling, this happened to a friend ... he caulked around the base of a leaky toilet because he didn't want to have to remove/replace toilet and fix the problem. About a year later he sat on the toilet and ended up in the basement because the joists had rotted. The paramedics were amused....See MoreSecond guessing bathroom floor tile & layout - keep or redo?

Comments (2)can't even see the floor tile! post a better pic. but from the little I can see, it seems to be fine, color-wise. yes, it's a bit more modern, but so is the style of your bathroom. warm things up w/some wood shelving, some art, towels, maybe a throw rug, some greenery but no, I would not do the same 12x24 wall tile on the floor. it's too much of the same....See MoreK
