Duke Concrete Products, Inc. is the Northeast Regions exclusive manufacturer of Rockwood Retaining Walls. The illustration above is an Albany County segmental retaining wall requiring NYSDOT compliant material.  The completed project is located on the corner of Schoolhouse Rd. and Krumkill Rd. This photo depicts the versatility of the Rockwood Classic 8 system with its radius curves.  Rockwood’s unique pitched texture offers the look of real stone in a simple, single unit system. See additional Retaining Wall options on our Landscape Products page or visit our large outdoor display on Bay Street in Queensbury.
