3 Benign Causes of Cracked Tile  

Many homeowners, probably not unlike yourself, are concerned that tile cracks are indicative of a serious, expensive, and structurally compromising issue. Not every tile fracture is cause for sleepless nights. Below is a brief outline of 3 benign cracks that do not pose a serious threat to the structural integrity of your home (but are still nevertheless a nuisance).  

Poor Installation Causes Cracked Tiles

Proper tile installation is everything, ensuring the tiles are flat, even, and secure. Poor tile installation can quickly fracture cracks through your kitchen, bathroom, and laundry room. One of the biggest examples of improper tile installation is not utilizing enough adhesive across the entirety of the tile (which results in an uneven position) This creates voids beneath the tile, which weakens the structural integrity of the porcelain and ceramic.

In addition to not using enough adhesive, sometimes the wrong kind of mud or glue is utilized. For example, mud/adhesive mixtures that allow for no flexibility once they dry are too stiff. It’s important to have a marginal amount of play to avoid fractured tiles.

Heavy Impact Causes Cracked Tiles

If you drop a heavy enough object on your tiled floor, odds are the tile will fracture. The tile is more likely to crack if there were installation problems to begin with – such as not enough adhesive and the wrong kind of adhesive. So, if you stumble upon a new crack, there’s a good chance your children or partner may have dropped a hefty item onto the tile.

Heavy Loads Cause Cracked Tiles

Heavy loads, such as hefty household appliances (refrigerators, washing machines, dryers, etc.), can fracture your tile due to intense, sustained stress. This generally only happens when weak, poor tile quality is used. It’s imperative to install the right type of tile for the right location/job. For example, wall tiles used on the laundry room floors are not strong enough to sustain your dryer.  

Two Serious Causes of Cracked Tile

Foundation Settlement and Foundation Heave Cause Cracked Tile

When we discuss foundation settlement and foundation heave, we are really discussing two sides to the same coin: expansive soil. Expansive soils, such as clays and loam soils, expand and contract in direct correlation with the water table. In short, more water expands the volume of the soil, and less water shrinks the volume of the soil.

This seasonal shrinkage and expansion exert a tremendous amount of pressure on your foundation. This can cause your foundation to sink, which we refer to as foundation settlement. Or it can cause your foundation to distend. This pressure travels through your foundation and up into the framing of your home, cracking tile along the way.

This is considered a more serious issue because simply replacing busted tiles won’t help. The root cause must be addressed, or you will be replacing tile into eternity. You will want to address the issue ASAP because if you do not, your home will continue to deteriorate.

The best way to address foundation settlement is through push pier and helical pier underpinning. To learn more about underpinning, read our article What is Underpinning (Definition, History, & Types).
