xpost: my new tile floor is CRUNCHY!
My new tile floor makes a crunchy sound when I walk on it! The floor was laid in early October and seemed fine. But not anymore! Is became noticable when the weather got cold.
For details, underneath the tile is a subfloor made of plywood. The contractor poured self leveling compound on the plywood to even out the surface before applying the tile.
Not all the tiles are equally affected. There are certain tiles that are noticably louder than others. The grout is intact, there are no visible cracks. I cannot really feel anything moving when I walk on the tile but I sure can hear it!
Does this crunchy sound mean that whatever the contractor used to fasten the tiles to the SLC is loosening and I'm hearing the sound of failing thinset? OR Was self leveling compound over plywood an inadequate base for a tile floor? Should he have prepped the base for the tile differently?
ARGH!!! I am really upset. Is this something that can be fixed? How should he fix it? BTW, the tile in question is on the second story of my house. I do have extra tile, fortunately...
