Consult the manufacturer for the design specifications of their product. In pervious concrete and porous asphalt systems, the concrete or asphalt mix specifications and construction procedures are key to proper functioning. These systems require well-trained and experienced contractors for installation.

===Foundation aggregates===
[[File:Geogitter-4.jpg|thumb|Geogrids like these are sometimes incorporated into the layers of permeable pavement foundation aggregates to provide additional stability]]
Most [[OPSS aggregates]] are not recommended for use in permeable paving systems. The exception being type 'o' with a default void ratio of 0.3.
*[[Choker layer]]
*[[Reservoir aggregate]]
===Geotextile===
[[Geotextiles]] are not always necessary and may be prone to [[clogging]]. Consider using courses of finer aggregates or sand instead.

Urban [[trees]] benefit from being surrounded by permeable pavement rather than impervious cover, because their roots receive more air and water. Block pavers around the base of a tree can be removed as the tree grows.
