Maximum Retaining Wall Height - Precast Concrete Horizontal Panels

The table below shows the maximum retaining wall height for each precast panel type for a variety of stored products. The span between support columns, the density of the stored material/product and the anticipated storage level will determine the type of panel that is most suitable for the application.
