· Unique large scale with modern, linear proportions
· Multiple face textures for each block size creates a natural quarried and random look
· Retaining walls and double-sided freestanding walls possible with the wall block. Blocks are finished on both the front and back faces and are tapered on each side approximately 1.5 in (38 mm) from the front to the back of the block.
· Corner blocks can be used to construct columns, provide a finished end on a freestanding wall, and make 90° corners. Blocks are finished on three sides, and the fourth side is tapered to fit with the other wall blocks.


The tapered sides of the blocks allow for construction of a wide range of curves in both retaining and freestanding walls. Walls are shown below 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.

• 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.


Kodah pillars can be constructed utilizing 1 full pallet of Kodah corner blocks. A 34 in (864 mm) column cap can be utilized to finish the pillar. The Column Cap can be cored as needed to accommodate the installation of a lamp.


Place (4) Kodah corner blocks with the same taper, facing into the center of the pillar.


Place a second row of (4) Kodah corner blocks with the opposite taper, facing into the center of the pillar.


Continue with subsequent rows to the desired pillar height. One pallet of corner
blocks will create a 32 x 32 x 36 in (813 x 813 x 914 mm) tall column.


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


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.
• 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.
