ᐅ Construction Tolerances

Hello everyone,

Some time ago, we had a pool built, and after installing the pool surround, we noticed that the stones of the pool edging were not laid level. Over a distance of 2 meters (6.5 feet), there is a height difference of 2 cm (0.8 inches) or more. It looks visually awful, and the construction company says this is completely within the tolerance of the German standard and therefore is not a defect.

Can someone help me and tell me if this is indeed within the tolerance or if I am being misled here? Thanks in advance.

Best regards
G

I sent photos earlier... the light-colored stone creates a wave in height. The black stone is plumb.
Ok, there is at least a standard for tiles and slabs regarding how much so-called overhang is allowed. Use that as a search term.

Thank you very much. I was not familiar with the term "Ueberzahn" by itself. Thanks for that.
