A 6 x 16 in double-sided, segmented retaining wall with tapered sides and an independent mechanical interlocking system, allowing for vertical or battered installation. The Semma wall also offers remarkable shear resistance (block-to-block contact), gap-free interlocking (four fill core system to receive contractor’s gravel), and a ½-inch joint for joint play. Featuring an integrated corner stone in each course, the Semma wall is the ideal solution for overcoming the raised patio impasse by erecting a self-supporting wall on which a parapet rests. Use Semma columns as a finishing touch, or add lighting to your wall or eye-catching visual elements. Ground finish available only in Canada.
