On the other hand if tiles are not bonded well then tiles and grout can crack and make a noise as they crack.
Tile floor cracking sound.
Answer answer i assume that the crackling noise that you are hearing can also be considered a squeaking sound that some say they hear on tile floors over wood sub floors.
This can occur when a mortar bed method is used and the mortar has delaminated from the supporting layer or when the subfloor itself is not sufficiently thick or well attached.
The snapping sounds are almost always traced to an uneven subfloor.
Sometimes you might walk across your floors and hear a popping or creaking noise.
If your wood floor is already down this might mean you have to pull up the section that squeaks to repair the subfloor and then put down a new section of flooring.
Laminate flooring materials don t tolerate humpy and bumpy subfloors.
Cracked tiles on floors and walls is a problem because it can be difficult to track down the source of the crack.
If the paint is blistering then that could be a symptom of a water leak.
If the floor has too much deflection that grout can crack among other things.
Floors that make a popping sound.
Depending on what s happening underneath the flooring these kinds of problems may be caused by among other things structure settlement or weak underlayment.
In many cases the crack is not the result of an inferior tile.
In far more instances the crack was caused by anomalies under or around the tile.
Subfloors need to be quite flat.
Occasionally a crack along the joint between grout and tile appears to be a crack in the tile s surface.
Occasionally a floor will sound hollow even when the tile is well bonded.
The question to determine is where is the water coming from.
Perhaps the tiles are still partially attached at the corners or somewhere in the middle but it s just a matter of time before a hollow tile begins to crack.
If your tile s crack seems to run along the tile s outer edge closely inspect the crack to determine if it s really on the tile or just.
