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.<br>

[[Geotextiles]] are not always necessary and may be prone to [[clogging]]. Consider using courses of finer aggregates or sand instead.

===Landscaping===

===Landscaping===

Landscaped areas should drain away from permeable paving to prevent sediments from running onto the surface. Urban [[trees]] benefit from being surrounded by permeable pavement rather than impervious cover, because their roots receive more air and water, and pavers used around the base of a tree can be removed as the tree grows.
