Rosetta Belvedere Information

Written by Barkman Concrete Published on September 13th, 2021


· Natural stone texture on both the front and back with multiple face textures for each basic block size to provide a more random look
· Creates both freestanding and retaining walls
· Walls, columns, fire pits and more mean multiple creative possibilities
· Wall blocks are tapered on each side approximately 1 in (25 mm) from the front to the back of the block
· Corner blocks are finished on three sides, the fourth side is tapered to fit with the wall blocks
· Corner blocks can be used to construct columns, create finished ends for walls, and make 90° corners
· Belvedere caps and coping available to coordinate with wall product


The taper on the side of the blocks allow for construction of a wide range of curves in both retaining and freestanding walls. Blocks in a retaining wall should be adjusted slightly in place and trimmed as needed to allow wall construction with proper batter. (For clarity, walls are shown below without batter.)

• Minimum radius curves are shown which can be constructed without saw cutting a significant number of blocks. Larger radius curves can be created by leaving a larger gap between blocks on the back side of the wall. The gaps must be filled with drainstone.
• When retaining walls are constructed with batter, the radius on outside curves becomes smaller with each course due to the block setback. For proper construction, the radius of the bottom course must be larger than the minimum radius so upper courses will have sufficient room for construction.
• When retaining walls are constructed with a batter, the radius on inside curves becomes larger with each course due to the block setback

Curved freestanding walls can also be built. Typically, the blocks have to be field adjusted to make the desired curve. Front and back faces will alternate and blocks trimmed as needed to provide a tight fit between blocks with no gaps on either side of the freestanding wall


• Some basic concepts are shown here for 90° corners. Plan to take some time to properly work corners into the larger retaining and freestanding wall patterns.
• Walls are shown without batter for clarity. Blocks in a retaining wall should be adjusted slightly in place and trimmed as needed to allow wall construction with proper batter.


Pillars make nice ends to freestanding walls, formal stair openings, stand-alone monuments, and other areas to enhance your Belvedere project. The basic steps of pillar construction are shown here. Feel free to expand on these ideas and bring your own creativity into a custom project.


Place (4) 3 in (76 mm) or
6 in (152 mm) high corner
blocks with the taper
facing into the center of
the pillar.


Place the second row of (4) of the corner blocks with the taper facing into the center of the pillar. Typically if the first row is built with 6 in (152 mm) corner blocks, the second row is built with 3 in
(76 mm) corner blocks.


Continue with subsequent rows to the desired pillar height. One pallet of corner
blocks will make a 24 x 24 x 36 in (610 x 610 x 914 mm) high column.


Place a column cap to finish the pillar. The column cap can be cored as needed for installation of a light.


Freestanding walls with pillars on each end can be constructed either with the pillars flush with the wall, or blocks trimmed to interlock the end of the wall with the pillar.


These drawings are representative of major components required in wall construction. Specific details including geotextile reinforcement layers, drainage details, soil requirements, etc. shall be per engineered design for the wall.

• These drawings are for preliminary reference only (not for final construction).
Final designs for construction must be prepared by a registered professional engineer using the actual conditions of the proposed site and loads.
• Final wall design must address both internal and external drainage and shall be evaluated by the professional engineer who is responsible for the wall design.
• Block size and placement shown are for reference only, individual Belvedere blocks will vary with installation pattern.
