Slip resistance on tiles

Tiles undoubtedly have many advantages. One of the biggest drawbacks of tile floors, however, are the problems with the risk of slipping and the sure-footedness of tile floors. What can be done against the risk of slipping, which floors are non-slip and which are non-slip, you can read in this article.

Slip resistance and cleaning effort

For all floor coverings, slip resistance and cleaning effort are two properties that are mutually exclusive.

The smoother a surface, the easier it is to clean. Conversely, rougher floor coverings are much more slip-resistant than smooth surfaces, especially when wet.

A compromise between the two properties can always be only a partial solution. In most cases, if you want surefootedness, you have to live with the slightly higher cleaning effort.

Different types of tours

When it comes to the professional assessment of the slip resistance of tile floors, you always have to make a difference in the type of inspection. The anti-slip depends very much on whether the tiled floor is entered with footwear or barefoot.

The check for slip resistance always takes place on the so-called inclined plane according to a well-defined technical verification procedure. The result is the so-called slip resistance classes, which are defined in the standard.

Non-slip classes

The slip resistance of tiles is determined by a standardized evaluation method, the results then lead to the slip resistance classes, which can be seen when buying tiles.

The slip resistance classes are denoted by the letter R and a numerical value. They range from R 9 to R 13.

  • Class R 9 - very low slip resistance
  • Class R 10 - normal skid resistance
  • Class R 11 and Class R 12 - increased slip resistance
  • Class R 13 - very high slip-resistant effect

There is a particular risk in so-called wet barefoot areas such as swimming pools or saunas. Here is to pay particular attention to a high slip-resistant design of tiles. The current standard differentiates between three types of areas (A - C), each with a different slip risk.

Validity of the skid resistance classes

Skid resistance classes must be considered by law only in commercial areas. For the private sector, these classes do not apply.

It should be remembered, however, that one may be held liable as the host. If, for example, a guest of the house falls on the tiled walkway to a cellar sauna, and it is proven that the tiles were not sufficiently slip-resistant for this area of ​​application, then you as a homeowner can have serious problems.

Also in the interest of your own safety, you should therefore pay attention to a high level of slip resistance, especially in endangered areas.


Porcelain stoneware tiles are generally non-slip in the ordinary version. This changes however by a suitable sealing, likewise with already ex-works surface coatings of the tile. Also, impregnating the tile, such as in outdoor applications, may be problematic in terms of slip resistance.
