A paving solution that applies permeable layers of asphalt over surfaces that allow infiltration and water runoff, thus improving stormwater management systems.

Composed of a layer of permeable asphalt placed over a granular drainage layer that is on top of a stone bed layer, porous pavement provides a higher amount of airflow on the paving surface, allowing it to be much more absorbent than regular asphalt. By creating an open-graded friction course, it allows rainwater to flow vertically into the soil, thus avoiding floods and accumulated water on traditional water-resistant surfaces.

Porous pavements are made of open-pore pavers, asphalt, or concrete with a supporting stone reservoir. It allows rainwater to drain into a thin stone bed below while this traditional stage works as a filter. Subsequently, a third layer made of bigger stones works as runoff detention, where toxins that get infiltrated along with the rainwater pass through the stone bed and travel into a sub-base, where they are subjected to the natural cleaning water processes.
