The bigger concrete pavers we would call “Betonplatten” = “concrete plates” and that is the source of this tagging error I believe.
the definition for concrete plates is: “ Heavy-duty plates placed closely together. Might have tar or sand in between the connections - or other filling such as grass or soil.”
the ones you showed are placed closely together and are made of concrete, are they “heavy duty”? I don’t think there is a definition for heavy duty that would help to decide edge cases. Maybe the term should be reinforced?
