Permeable paver systems typically consist of strong structural materials containing regularly interspersed void ares, which are filled with pervious materials such as gravel or sod. A generalized sketch of a pre-case castellated concrete paving system is shown. Pre-cast systems can also be made up of lattice grids, or designers can use modular unit pavers, such as interlocking concrete blocks. In addition to these structures, porous concrete is a permeable option that allows for infiltration through the concrete structure itself.
