Permeable pavements are a type of surface material designed to allow water to pass through them, reducing runoff and promoting groundwater recharge. They are made from various materials, including porous asphalt, permeable concrete, and interlocking pavers, which create spaces for water to infiltrate. These pavements help manage stormwater by filtering pollutants and reducing the risk of flooding. They are often used in parking lots, driveways, and walkways, making them an eco-friendly alternative to traditional impermeable surfaces. By facilitating natural water absorption, permeable pavements contribute to sustainable urban development.
