I have a problem with water going through the tile/grout and leaking into the ceiling below. I've had the tile regrouted and sealed and the tub recaulked. Ths a recurring problem, I've repaired the ceiling twice. Also, I don't think the builder used cement board on the walls just sheetrock.
Anyone have a solution for this problem?
Thanks in advance
Did you check the grout for hairline cracks.? If it has cracks, Use the first below to figure maximum deflection of your floor for tile. Use the second link to determine the deflection of your floor itself to see if the floor needs to be strengthened by bracing, backer board, etc..
Also, did you check any piping for leaks such as drain for the tub or water line.?
Just for clarification... do you have a bath tub with a tiled surround or do you have a tiled shower pan? What I'm basically asking is does water naturally sit on the tile, or is the only contact with the tile from water splashing?
I have the same issue with my Bathroom wall tiles. What kind of grout or caulk should I use? thanks.
When the tile on the floor was laid did they put a mat down (its just for things like this, extra protection against leaking down to the first floor ceiling). It goes in front of the tub or shower. Also did they put a silicone sealer on the grout. If it was natural stone instead of tile, you would need a stone sealer. Seal it until water beads up, it shouldn't take more than two coats.
Silicone sealer should do the job just fine. If you have to use some kind of other sealer, use only silicone not caulking. Caulking comes up after a while. I always use a clear silicone (in the tube) to seal around a shower or tub enclosure. And it looks a lot cleaner too.
The above response is for my home.
Examine the grout work around the area where you suspect the leak.
Remember that a leak may originate in a distant location and wick or run
to the point where you are observing a problem.
