AZEK uses 95% recycled material from rubber tires in its new VAST landscape pavers. They are one-third the weight of concrete and are billed as being able to install three times faster than traditional pavers thanks to the grid system that underlays the pavers, holds them in place, and keeps them aligned. VAST pavers are suited for landscape use as well as roof decks, driveways and parking lots. There is a permeable paver in the line, and the blocks come in five colors: Redwood, Boardwalk, Olive, Village, and Waterwheel. 877.275.2935.
