What does the term "deflection" refer to in tilesetting?

The thickness of the tile
The amount of bending in a subfloor under weight
The layout pattern of the tiles
The weight of the tiles per square foot

The correct answer is: The amount of bending in a subfloor under weight

The term "deflection" specifically refers to the amount of bending or movement that occurs in a subfloor or structural element when weight is applied to it. In the context of tilesetting, this is a critical consideration because excessive deflection can lead to tile cracking, grout joint failure, and overall compromised integrity of the tiled surface. Materials used in flooring systems have specific deflection limits that must be adhered to in order to ensure that they can support the weight of the tile as well as foot traffic without detrimental movement. This concept directly relates to the proper installation practices and can affect both performance and longevity of the tiled surface. Understanding deflection is essential for tilesetters to ensure that the substrate is suitable for the intended tile installation and to prevent potential issues in the future.
