Ascona / CH Castello del Sole

The foundation stone of the present hotel was laid in the winter of 1945/46. In the winter of 2007/2008, a spa was created on the ground floor. The specialists at STEULER-KCH were responsible for ensuring it remained watertight, and received the order for carrying out the waterproofing work of the hydropool, the two whirlpools, the piazza, the Kneipp pool and the stream. The surfaces were lined using the tried-and-tested multi-layer STEULER Q⁷ waterproofing system.
