Important Information
Handling & Installation – Maximum height - 36" (under optimum conditions) but can be engineered for walls that require to be higher. Higher walls can be achieved using geogrid reinforcement. Walls greater than 4' in height require professional engineering. Tapered units will allow for a minimum 5ft. outside radius. To achieve this radius, you must use stones of the same taper on one layer, and stone of the opposite taper on the next layer. XL Tapered units allow for an 8 ft. radius. The set back on Pisa2 wall is ¾" every course or 1½" every 2 courses.
Unilock, through Risi Stone® Systems International, can provide preliminary site engineering for most commercial projects. Soils information, site drawings, and loading requirements are some of the information details required in order to provide this preliminary site engineering.
