Cracking, tenting and debonding usually start at restrained edges , long runs or poorly prepared transitions rather than in the tile itself. RUBI supports a more controlled approach to tiling movement joints, combining correct joi...

    How to design and fit movement joints
    If the tile-to-tile joints between ceramic tiles are the essential elements for reducing the rigidity of a tile covering on its outermost layer (that formed by the tiles themselves), then the tile expansion joints constitute the multilayer construction solution for absorbing the different types of forces arising fro...
