Occasionally, a floor will sound hollow even when
the tile is well bonded
. 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. … Over wood, floor failure is more likely.
What causes hollowness in tiles?
Causes of hollowness
Mixing too much of water in mortar mix used below the tiles
, leading to evaporation and leaving voids on drying up. In large rooms/areas laying the tiles wall to wall without leaving gap for thermal expansion and contraction in the ends, leading to popping up of tiles when the space contracts.
How can you tell if a tile is hollow?
A simple way to check for the sound in question is
to tap on the tiles with
a hard object such as a steel ball bearing. Chains or special sounding devices can be used for larger areas. If the tile is well bonded (i.e. attached to the concrete substrate), it will have a high-pitched sound.
Will a hollow tile crack?
In some cases hollow sounding tiles
are not likely to result in any problems
. … Tiles with voids under them are more problematic in commercial applications where the tile could be subjected to heavy traffic and heavy point loads, which could result in the tile crushing or cracking in those spots.
Should hollow tiles be replaced?
ANSWER – Hollow sounding tile is not a defect per industry standards. Although a hollow sounding tile can be a symptom of a defect. … If there is no resultant damages to the tile or grout, then I would just let it go. Make sure
you have extra tile for the future

How do you fix a hollow sound in tile?
- Step 1: Collect your tools:
- Step 2: Place your iron over the tile to loosen the adhesive.
- Step 3: Pry the loose tile out with a putty knife.
- Step 4: Use mineral spirits to dissolve adhesive.
- Step 5: Scrape away the old adhesive with your putty knife.
- Step 6: Apply the new tile adhesive.
Are loose tiles bad?
Not necessarily. Tile adhesive is virtually never the problem when a tile comes loose. Instead, loose tile is an
indication that some component of the tile-backing system has failed
, allowing water to get in and destroy the bond.
Why are my floor tiles moving?
One of the most common reasons that tiles move is
backerboard that was improperly installed
. The old backerboard will have to come up so that new backerboard can be put down properly. Pry up any loose sheets with the pry bar. If the sheets are screwed down tightly, unscrew them, then remove.
How do you check if tiles are laid properly?
To check a row of tile,
line up the laser with a grout joint and point it straight across the room
. Have an assistant hold the laser while you check from one end to the next. The grout joint and edge of the tiles should match the laser right to the end; if they don’t, the tile is not straight.
Does grout strengthen tiles?
Grout is used as a filler for the joints between tiles once the tile you are installing has been set. … it helps keep dirt and debris from getting in between and under your tile. It
adds rigidity and strength to the tile installation
.
What causes floor tiles to lift and crack?
The cracking and expansion of the concrete normally happen
when the weather is warm
. When the weather is cool, buildings tend to contract. If heat is turned on in the house, it creates a lot of pressure in the room. So, the tiles may lift as a result.
What causes floor tiles to buckle?
Floor Expansion or Shrinkage
Tile is a porous substance; therefore, over time it can swell with high moisture.
With enough expansion, the pressure can cause the tile to
pop up, resulting in a buckling floor. … Tile or a sub-floor set in a humid environment may shrink if humidity is reduced for an extended period.
Why is my tile making noise?
Tiles can expand as they are subjected to moisture in the form of humidity or water, or if they are subjected to temperature changes or if the tile floor has excessive deflection. … Another reason why tiles could be making noise when you step on them, is
if they are installed over a wood substrate
.
How do you stop floor tile grout from cracking?
Vacuum the crack thoroughly to capture any dust left behind. Next, choose a replacement that is less likely to crack:
silicone caulk
. The primary benefit of using caulk is that it’s flexible. If your cracks are caused by shifting surfaces, a line of caulk may survive where grout failed.
