Nature's Drainage: The Secret Behind Porous Pavement #teamwater Porous pavement is an innovative solution to urban waterlogging, inspired by nature’s own drainage system. In natural environments, vegetation slows rainfall and porous soil allows water to soak in and filter through. Engineers have replicated this process by designing pavement that mimics these properties. Unlike traditional asphalt, porous pavement contains fewer fine particles, creating tiny air pockets that let rainwater seep th
