Techo-Bloc Semma Wall
The Techo-Bloc Semma Wall is a 6″ x 16″ double-sided segmental retaining wall designed for strength, versatility, and ease of installation. Its tapered sides and mechanical interlock system allow for either vertical or battered wall construction. Featuring a four-cored system filled with gravel for enhanced stability, Semma is ideal for raised patios, retaining walls, and parapets. The integrated Coin design on each layer ensures seamless alignment, while optional Semma pillars can add decorative or functional elements such as lighting.
