Client: Municipality of Zollikon, Fohrbach Swimming Pool, Switzerland
Assignment: Anti-slip treatment in changing rooms, restrooms, showers and sauna area.

Substrate: Porcelain stoneware tiles.

Antislip Solution: SWISSGriP for pools and spas floors
Slip Resistance: Slip resistance class C and R11
Class C:      DIN EN 16165 / DIN51097 – Angle of inclination ≥ 24°
Class R11:  DIN EN 16165 / DIN51130 – Angle of inclination 19°-27°

Anti-slip treatment of wet porcelain stoneware tiles.

In a public bath, the floor covering in changing rooms, saunas, toilets and showers is given an anti-slip treatment.

Tiles that are slip-resistant when dry become slippery when wet and damp. In physics, this effect is explained by friction or, in the case mentioned, by the reduction of friction. The effect of reduced friction is well known, especially when we are walking on edges and is called "aquaplaning".

The Fohrbach swimming pool is a bathing facility operated by the municipality of Zöllikon. The public swimming pool houses several indoor and outdoor pools. From the Olympic pool to the pirate ship, visitors can choose between the pools. The wellness area around the sauna, showers, restrooms and changing rooms are fitted with the same porcelain stoneware tiles. Splashing water, high humidity and wet feet cause puddles of water or even just a wet film to form on the flooring. Both scenarios lead to the aforementioned reduced static friction and the tiles become slippery and slippery as a result.

The technical management was looking for a solution to subsequently increase the static friction and thus ensure the tread resistance of the tiles even when wet. We carried out an anti-slip treatment of the walkways and endangered areas by cleaning the floor covering thoroughly and then spraying it with the SWISSGriP system. The adhesive friction value of the tiles was increased with the anti-slip treatment and is now C (highest slip resistance) for bare feet and R11 for shoes.
