Anti-slip tiles: slip resistance retrofit.

Tiles with subsequent anti-slip in pool environment, changing rooms and spa.

Alsik Nordisk Spa & Wellness is the largest spa in Denmark. Guests can choose from more than 60 different spa and wellness experiences spread over 4,500 square feet on four floors. The spa offers guests to relax in various pools, saunas, steam rooms and whirlpools. Children have their own pool, and outdoors, a 30-degree pool with salt water is added.

Various porcelain stoneware tiles with R10/A+B surfaces were installed in the wet areas of the spa. Porcelain stoneware tiles are by far the most popular tiles to install on the floor. Porcelain stoneware tiles are characterized by their excellent technical properties and are also suitable for outdoor installation due to their low water absorption. However, despite the anti-slip standards R10/A+B, the tiles were slippery, especially in areas where the floor tiles come into contact with a lot of water: Swimming pool surround, walkways, showers, kids spa, etc.

GriP Safety Coatings was contacted due to the slippery tiles and coated the tiles at the kids pool. The anti-slip coating made the tiles slip-resistant and slip-proof, even with a lot of water on the surfaces from the kids' splashing. The operators of the spa then commissioned GriP Safety Coatings to treat all of the slippery tiles (759 m²) with GriP Anti-Slip. Since then, the tiles have sufficient slip resistance with and without puddles of water.

Evaluation classes for anti-slip tiles

Since the anti-slip coating with GriP the tiles have slip resistance class C. This is the highest rating class for tiles in barefoot areas. The testing of the slip resistance of floor coverings in wet barefoot areas is carried out for the evaluation classes A, B and C by means of an "inclined plane" according to DIN 51097.
The floor covering to be tested is placed on a level. Then a text person walks barefoot on the wet flooring. The level with the floor covering is thereby brought into the inclined plane. Meanwhile, the angle of inclination of the inclined plane is checked and recorded. The floor covering is finally given the evaluation group at whose angle of inclination the test person could still walk barefoot without slipping and with surefootedness. The angle of inclination at which the slip resistance is still given is also called the minimum angle of inclination.

In the case of the evaluation class C used here, the slip resistance of our SWISSGriP coating is guaranteed up to at least 24 degrees. The above mentioned evaluation classes are for barefoot areas, but GriP anti-slip coatings may of course also be walked on with shoes.
