We are also certified installers of concrete segmental retaining walls. The National Concrete Masonry Association (NCMA) specifies precisely how these systems should be installed.

Cosmetics aside, there are numerous ways that walls can fail, often with a disasterous conclusion. Most municipalities now require that walls over four feet high have a stamped and certified engineering plan for its construction. This piece of paper can cost upwards of $1,000, and we refuse to install without it.

Decorative and retaining walls follow the same process as above for the base course installation. Ample drainage opportunities beneath and behind even a two foot wall are essential. Otherwise, water in the winter will freeze, expand to THREE TIMES its size, and heave that wall slowly out of the ground. There are multiple factors influencing every design, material and construction decision when building a wall. If you award us the work on installing a wall, we will have it engineered by the manufacturer, follow their specifications, and guarantee the installation.
