Tile industry associations recommend special total load deflection limits the following tables list the components and weights of typical floor systems along with the deflection limits that apply.
Ceramic tile deflection limits.
The l stands for length.
However the limit of span 360 was often misunderstood as the same limit for framing members specified by the building code.
Ceramic tile live load deflection shall not exceed l 360 stone tile live load deflection shall not exceed l 720 the owner should communicate loading requirements to the designer designer and contractor must make allowances for all live and concentrated loads including during construction and maintenance such as heavy.
Until recently the tile council had specified a standard for ceramic tile only based on using test equipment that was intended to limit deflection of floor sheathing.
These deflection limits apply both to the framing supporting the substrate and to the substrate itself for example when a concentrated load is applied between joists.

Whether you are installing stone or ceramic tile over floors and walls there s one thing to consider.
So if you have a beam 20ft long the allowable deflection limit is 20ftx12in ft 240 1.
Some large natural stone tiles that aren t as uniformly strong as ceramic tile may require an even stiffer structure.
