Permeable paving is not typically used in locations subject to heavy loads. However, some permeable pavements are designed for heavy loads and have been used in commercial port loading and storage areas.  A flexible geogrid structure may be used to improve the structural capacity of the pavement by spreading loads over a larger area.  Increasing the base thickness will also improve structural capacity.
