This table shows summarizes specifications for permeable pavement.

|Permeable Pavers||Surface open area: typically 5% to 15%; minimum thickness: 3 inches for vehicles; minimum compressive strength: 8,000 psi||Concrete pavers conform to ASTM C936 and clay pavers C1272. Reservoir layer required to support the structural load.|
||May not require a reservoir layer to support loads, but a layer is required for storage/infiltration. In no case should plain steel rebar or mesh be used in pervious concrete as this invites corrosion.|
||Reservoir layer contributes to structural load support.|
