The Importance Of Expansion Joints In Tile Installation

When you are looking for a tile contractor or if you already find the right one for you, one of the things that he will tell you is that expansion joints are incredibly important in commercial tile installation.

The truth is that no matter if you are hiring or just hired a restaurant tile contractor, an office tile contractor, a barber shop tile contractor, a commercial floor tile contractor or even a commercial wall tile contractor, you need to ensure that this contractor is well aware of the importance of expansion joints in tile installation.

What Are Expansion Joints?

Simply put, expansion joints are “A joint through the tile, mortar, and reinforcing wire down to the substrate.” By integrating these “stress relievers” into the tile assembly, expansion and contraction takes place without compromising its integrity.”

It’s worth pointing out that expansion joints are also known as movement accommodation joints or as movement joints. Besides, whenever you are installing stone, glass, porcelain or ceramic tiles, they are crucial to ensure that their installation lasts for a very long time and without any problems.

Pay Special Attention To Rooms With More Sunlight

The reality is that when you hired a commercial tile contractor for a commercial tile installation in a room that tends to get a lot of sun, then expansion joints are even more important. The main idea to keep in mind is that those areas that tend to get warm or wet might experience greater amounts of differential expansion. This means that areas that tend to get more sun or are more exposed to sunlight are usually warmer. Therefore, expansion joints should be used more frequently.

Other Reasons To Pay Attention

The truth is that a room getting more sunlight isn’t the only reason why you should use expansion joints. In fact, the tile installer should consider determining some space for expansion joints when:

  • there is deflection and vibration of the substrate, especially with suspended slabs.
  • there are changes in the plane of the substrate
  • there is seismic activity
  • when there is continued curing of the concrete substrate which can put the tile in compression
  • when you need to install the tiles in a location of weight-bearing columns.

The Expansion Joints Material

As you can imagine, expansion joints need to be made with a different material so they that easily contract and expand when necessary. In what concerns floor applications, polysulfide, neoprene, and urethane tend to be the materials that are used more often. In cases where traffic isn’t a concern, the commercial tile contractor may opt to use silicone as well.
