Why Do Tiles Come Out from Floors and How to Fix Them

Have you ever noticed tiles popping up from the floor, causing frustration and concern? This issue is not uncommon and can disrupt any living space. In this comprehensive guide, we will explore the possible causes and solutions for tiles coming out of floors, providing you with the information you need to maintain the integrity of your flooring.

Identifying the Causes

Several factors can lead to tiles coming out from the floor. Understanding these causes will help you implement the necessary measures to prevent and fix the problem.

Air or Moisture Trapped Under Tiles

One of the primary reasons tiles may come out is the presence of air or moisture beneath them. Air pockets can form during installation if the tiles are not properly laid, while moisture can accumulate if there is a leak or if the floor has been exposed to water. This build-up of air or moisture can cause the tiles to become loose and eventually come up from the surface.

Another contributing factor is the lack of spacers between tiles during installation. Spacers ensure that the tiles are correctly spaced and pressed firmly against the subfloor, preventing any gaps or air pockets from forming.

Improper Laying Process

Improper laying of the tiles themselves can lead to this issue. If the tiles are not placed correctly or if the bedding material is not adequately prepared, the adhesive may not provide sufficient binding. This can result in the tiles becoming loose over time, leading to a buckle or a pop-up feeling underfoot.

Loss of Bond and Settlement

One of the most common reasons for tile comeouts is the loss of bond between the tile and the subfloor. Several factors can contribute to this, including movement of the flooring structure, freeze-thaw cycles, and cracking of the tile. In some cases, especially in older buildings, the flooring may have settled over time, leading to gaps forming and tiles becoming loose.

Visual Inspection and Professional Help

To determine the exact cause of the problem, a thorough visual inspection is often necessary. If you suspect you have a significant issue, it may be advisable to consult a professional floor tiler or a building inspector. They can provide a detailed assessment and recommend the appropriate course of action.

Fixing the Issue

Once you have identified the causes, you can take steps to fix the problem and prevent it from happening again.

Remove and Relay the Tiles

If air or moisture is the main issue, you may need to remove the tiles and re-lay them with proper spacers and a new adhesive. This ensures that the tiles are correctly bonded to the subfloor and will not come out again.

In some cases, it might be necessary to re-level the floor by removing any settled areas and applying fresh bedding material. This process may require specialized tools and techniques to ensure the tiles are properly sealed and bonded.

Prevent Future Issues

To prevent tile comeouts in the future, ensure that proper procedures are followed during installation. This includes using a thick slurry of cement under the joints, applying a layer of cement mortar, and ensuring that spacers are used correctly.

Regular maintenance, such as sealing any cracks or leaks, can also help prevent moisture buildup and further damage to the flooring.

Conclusion

Tiles coming out of floors can be a frustrating issue, but with the right knowledge and steps, you can address the problem effectively. By understanding the potential causes and working with the right professionals, you can maintain the integrity of your flooring and enjoy a safe, comfortable living space.
