Capabilities Chart FREESTANDING & RETAINING WALL
This chart provides general construction limits based on a typical planter bed behind the wall. Reference the available Estimating Guides (Nueva ® , Ortana and Proterra TM ) for higher retaining walls, where there is any sort of load (slope, fence, traffic) behind the wall, or where any other special conditions exist. Design support is recommended when there is a pedestrian guard required [area behind the wall is accessible and the wall height exceeds 600mm (23.6”)] and/or a building permit is required [wall height exceeds 1,000mm (39.4”)].
