travertine pool deck holes
We had a new travertine pool deck installed recently. We are seeing many tiles with holes larger that 1 inch - some 3+ inches (the holes don't go all the way through the tile - but are often at least half way through tile). We expected some small holes and imperfections but these are larger then we expected. Is this normal?
Should we replace these tiles? And if we do - does that involve just lifting the tile and inserting a new one or is there more to the process?
Should these holes be grouted? Or some other treatment?
Should we expect more large holes to appear?
Any recommendations and suggestions would be appreciated.
Thanks for your help.
