Century Series pavers is our fancy way of saying "tumbled pavers." These pavers have been tumbled to create a soft aged feel. Not only do Century Series pavers add "old-world" charm to your landscape (who doesn't want that?), they also provide a more inviting, natural feel. There is another upside to paying more for tumbled pavers. The pavers are already look old. So, instead of getting old and worn looking as the years go by, they look just as good or better than the day they were laid. Plus, they are meant to look aged - making them an excellent low maintenance choice in any outdoor living space. Did I mention that moss looks really good in the joints of Century Series pavers? I love that in shady spots in a landscape.
