Not every slope needs a retaining wall. Block retaining walls allow attractive, flexible designs for soil retention, structure support, and expanded seating. They are great for small and difficult to access projects. Usually engineering is required for walls over four feet tall; even below this height, proper install methods is critical to avoid walls falling over under the pressure of roots, soil, and, most importantly, water. Many of our project managers and installers have taken classes from the National Concrete Masonry Association in segmental retaining wall installation.
