Precast Concrete Bunkers - Maximum Wall Heights

The design of storage bunkers will depend on a number of factors. The table below gives the maximum wall height by panel type for a variety of stored products based on the density of the material, the anticipated storage profile (surcharge or level fill) and, in the case of the horizontal panels, the span between the supporting columns.
