Modular Retaining Wall System

The SUBSTIWOOD® retaining wall system consists of three interlocking types of blocks: base, main, and cap. Each retaining wall main block covers approximately 1 sq. ft., has a length of 2 ft. The cap block has a rounded face brick pattern. Pilaster columns and caps for retaining walls are also available. Two types of pilaster caps (“brick” pattern and “globe”) are available. Pilasters are typically placed at wall corners and at general spacing of 8-12 ft. Curved 6-ft and 7.5-ft radius blocks (inside and outside curves) are also available! For color choices, see color page.

Columns (Piers) and Caps

Use these columns with your signs (shown below) or with metal fencing. A foundation must be used to support the columns. These unit are hollow inside to reduce weight. Two types of caps are available. Contact us for other sizes and designs.
