Techo-Bloc Semma Wall is a robust 6″ x 16″ double-sided segmental retaining wall engineered for strength, stability, and design flexibility. Featuring tapered sides and an independent mechanical interlock system, it supports both vertical and battered wall designs with ease.
Designed for high shear strength and durability, Semma’s four-cored system allows for contractor-filled gravel voids, enhancing block-to-block contact and structural integrity. A ½” bond between units ensures optimal joint dispersion, making it ideal for complex hardscape projects.
With an integrated coin on every layer, the Semma Wall is the go-to solution for raised patios, allowing builders to create a structural wall with a free-standing parapet cap. Complete the look with matching Semma pillars to incorporate lighting or add architectural impact.
