Stone Tile: Absorption Rating

Porosity of Natural Stone Tile

The absorption rating measures the porosity of each type of stone. Most natural stone tile is somewhat porous. With a higher absorption rating, the tile is more likely to stain and more likely to crack due to freezing temperatures.

As a result, these stone tiles should not be installed outdoors. Sandstone is typically the most porous stone and granite is one of the least porous options. The finish of a stone tile can also affect the absorption rating. For example, polished tiles tend to absorb less water. There are four main categories used to classify the absorption rating of stone tiles: non-vitreous, semi-vitreous, vitreous, and impervious.


- Highest absorption rating (above 7.0%)
- Should not be used in areas with excess moisture
- Not ideal for foot traffic


- Second highest absorption rating (3.0-7.0%)
- Exposure to moisture will increase maintenance costs
- Not recommended for foot traffic


- Absorption rating between 0.5 and 3.0%
- Preferred by professionals
- Equipped to handle indoor foot traffic
- Some are acceptable for outdoor installations


- Least absorbent (0.5% or less absorption rate)
- Relatively waterproof
- Works well in high traffic areas
- Commonly found in commercial properties
- Low maintenance, wipes clean
