The natural stone coping from Unilock really helped put the finishing touch on this large scale patio. The patio was constructed over a gravel base using Unilock Beacon Hill Flagstone pavers in the Steel Mountain color with a Copthorne Basalt accent. The retaining walls, steps and fire pit were constructed using Unilock Brussels Block complimented with the Black River natural stone coping. This patio will host a lot of family and friends with over 1,800 square feet of patio.
