An entirely new concept to the landscaping earth-friendly market, GreenRock is transforming gardens and landscape projects from ordinary to extraordinary. Its unique natural color and texture is the result of a special blend of concrete roofing tiles, concrete paving stones and concrete block that have been recycled. It can produce the ultimate finishing touch to a drought-tolerant landscape and, since GreenRock doesn't actually grow "green," there's virtually no maintenance to keep a yard looking like paradise.
