Any ideas what would cause a ceramic floor to buckle up for about a stretch of 20 feet? This is on a house built in 2016. There are no cracks in walls or in the perimeter of the foundation. It’s a recent problem because the Realtor said it wasn’t like this a couple of weeks ago when he first looked at the property. Guess I’m lucky it didn’t happen after the inspection.
Subflooring is the only thing that comes to mind.
A little more info would help.
Slab on grade? Pier & Beam ( crawl space)? Ground floor?

Thanks Marcel.
interesting read Marcel…
Here is another perspective where heat (sunlight or other) may also promote expansion.

I used to install tile, as with any flooring there needs to be expansion gaps along all the perimeters. Also could be lack of backerboard and sub par thin-set.
