Hairline crack in floor tiles

#1 Post by rabbit »

Our house has a sous-sol that is the same area as the ground floor. I noticed a fine hairline crack in the 50cm ceramic floor tiles that extends across two tiles. The sub floor is concrete beams with concrete block infills.
I have looked at the ceiling of the sous sol where the problem is located. I can’t see any cracks or deformation but some of the concrete is covered with artex. House was built 17 years ago by a reputable local builder. The crack is so fine as to not pose any cosmetic issue at present.
What should I do?

I'm afraid that structural movement is inevitable. The Tour Eiffel moves also a little bit, seasonal influences, so you are in good company....Prolonged dry weather is becoming more of a problem, everywhere. The traditional little red tomettes are easier to live with: cracks will follow the joints. Ceramic tiles of 50 cm (how thick, many producers) are more vulnerable.
