Porous pavement is a type of surface material designed to allow water to pass through it, reducing runoff and promoting groundwater recharge. It is made from permeable materials like concrete, asphalt, or gravel, which create voids that enable water to infiltrate the ground below. This helps manage stormwater and can prevent flooding in urban areas. In addition to its environmental benefits, porous pavement can also improve the durability of roadways and parking lots. By allowing water to drain through, it reduces the risk of surface erosion and damage from freeze-thaw cycles. This makes it a sustainable choice for both residential and commercial developments.
