Porous pavement and permeable pavers are materials, structures and pavement designs that are specifically designed to allow water to pass through them so they can infiltrate into the underlying soils. They can be made of pervious concrete, porous asphalt, or permeable interlocking pavers.
This practice could be particularly cost effective where land values are high and flooding or icing is a problem. Currently, they work well when used on driveways and patio areas.
Slow water down allowing infiltration
Reduces runoff volumes and rates
Uses less de-icing material since runoff is infiltrated
