Can the tiles be laid outside?
Ceramic tiles can be laid outside and are often seen laid in the front garden walkway of Victorian villas. Cold and sub-zero temperatures in winter and hot temperatures in summer months will not damage the tiles and the density of ceramic makes it almost impenetrable to moisture and subsequent freezing. However if a tile cracks owing to an accident etc. it is wise to replace it as freezing and thawing will eventually likely widen the crack, break the tile and perhaps start moving tiles in proximity. Carreaux de ciment tiles cannot be laid outside as the cycle of freezing and thawing will eventually break the tiles.
