Permeable pavers, also known as pervious pavers, are flat blocks that allow water to drain directly into the ground. They are ideal for any form of eco-friendly landscaping for this reason. Capturing rainwater before it runs into the streets reduces the likelihood of flooding. Also, keeping rain water, which carries many pollutants, from reaching storm sewers reduces the amount of contaminated water that enters the water supply. Pervious pavers are quite strong. They can support a tremendous amount of weight, which is why they are often used in commercial construction. In the domain of residential landscaping, they are most often used to build driveways, patios in sensitive areas, patios near vegetation, and hardscapes connected to retaining walls built for land retention purposes.
While details of designs vary widely, the fundamental design of permeable pavers is remarkably simply. A grid of some sort creates the basic frame for the design. Within the gird, a variety of porous materials is introduced that will filter rainwater directly from the hardscape surface directly into the ground.
