With its bold and dramatic presence, Unilock’s SienaEdge Wall Block (each weighing a minimum of 380 lbs) creates a striking impression whether used in robust retaining walls or as stair treads for expansive outdoor staircases. SienaEdge’s elongated lines and split-face texture offer a visually appealing alternative to more utilitarian wall blocks.

It can support gravity walls up to 10 feet (3 meters) high and grid-reinforced walls up to 40 feet (12 meters) high under standard engineering conditions. Additionally, coping units are offered to complete your project. Whether used to create expansive terraced gardens, define property boundaries, or support elevated landscapes, Unilock’s SienaEdge Wall offers both strength and aesthetic appeal, ensuring lasting performance and visual impact in diverse outdoor environments.
