We contracted with a sub to install "4 Piece French Design Scabos Travertine" decking. Install happened last week while we were out of town. There are a number of issues that I am going to meet with the sub about, but there is one issue I am hoping to hear your collective wisdom on: instead of installing the travertine in a repeating French pattern, the installer placed pavers randomly, so there is no pattern whatsoever. I am weighing how much this bothers me, but my question is beyond aesthetics, what are some practical reasons to insist on a "French" or Verseille pattern over just random placement of pavers? There are some spots where there are continuous grout/joint lines that would be eliminated if the sub had followed a French pattern, and I think that goes beyond aesthetics. Others? Thanks in advance...
