The height will depend on site conditions and the type of product used. When a Rockwood wall is engineered and geogrid is incorporated in the design, a Rockwood wall can exceed 30' in height. If you are building a wall that is 4' or higher, we recommend that you seek a local qualified engineer to approve the design. What is the NCMA?
