The CSS Group is an insurance company of long-standing tradition based in Lucerne. Founded in 1899, CSS Versicherung employs 2,500 people. For safety of employees and visitors the floor of the company canteen was to be made permanently slip-save. Anti-slip mats were out of the question for hygienic and optical reasons. With GriP Anti-Slip coating, slip resistance class R11, the porcelain stoneware tiles were non-slip coated within hours. In the prictures you see that even the floor tiles are of very dark color the transparent SWISS GRIP coating is still almost invisible.
