Installed alone or with Radius or Transition sections, Hanover's RockCurb® Straight sections are the most widely used type of RockCurb®. RockCurb® Straight sections are 36” long and 6” thick with a 12” or 18” height. Both heights are available in both the Battered and Bullnose Profiles. RockCurb® units are consistent in size and many times more durable than poured in place curbing. These high density concrete units are manufactured to 1/8” tolerances simplifying the installation. A 1/8” joint is recommended to allow expansion through freeze-thaw cycles. RockCurb® can be easily reconfigured and reinstalled to accommodate changes or repairs.
