Since 1921, Durastone Corporation has distinguished itself as New England's leading manufacturer of precast highway products. The Durastone name is synonymous with zero slump curb, median barrier, drop inlets, light bases, and a variety of other related items used in road construction. Durastone has made the "right now" delivery of precast concrete products a reality. We stock standard curbing in 6', 5', and 4' lengths, as well as radius curb from 2' to 100', so there's virtually no waiting for delivery.
