Crunching Floor Tiles

Recently i noticed that a few of the floor tiles in the kitchen make a crunching sound when walked on.

Crunching floor tiles.

So it is hard to say if a crunching sound is a squeaking sound or what. Most tiles meet the 250 pound minimum. Installing ceramic floor tile is fairly simple until you reach the edges of the room or fixtures such as cabinets pedestal sinks and toilets. My house was built in 1956.

On closer inspection i can see that the tiles are moving very slightly against the grout which is causing the sound. There is a almost unnoticeable bulge where one of the tile comes up. Ceramic floor tiles especially larger tiles need an even distribution of mortar underneath them. For a larger more visible area of cracked tile contact a tile contractor for expert help.

It is the original tile with no signs of repair or cracks in the tile or grout. As stated above if the floor is installed over a wood substrate and not placed in a staggered pattern with gaps and not fastened properly floors with ceramic tile installed over them can squeak. As a general rule tiles larger than 12x12 inches should have mortar applied to the back of the tile as well as the floor to help ensure adequate coverage. Reinforcing your floor will make for a more solid and level surface.

If the floor has too much deflection that grout can crack among other things. I have owned it since 2012. Tile floors are easy to customize easy to clean and make for a classy addition to any home. There is ceramic tile on the floor in the second floor bath.

In these cases you must grind down the ceramic floor tiles so that they fit around these objects. Voids in the mortar under the tile allow the tile to flex and crack. There is an area about 15x15 inches that makes a crackling noise when you step on it. Grinding ceramic tile can be tricky since the hardness is similar to glass and it can crack.

As long as the tile does not break under 250 pounds of pressure the tile is considered to be compliant with these standards. However there are steps you can take mitigate tile cracking. It takes combined collaboration between the builder the end user the involved manufacturers and the flooring professional to be able to mitigate the causes. Most tiles comply with astm c648 breaking strength standards.

Many of the causes of squeaking popping and crunching sounds that come from the flooring system are avoidable.
