Porous Pavement

You can spray a garden hose on porous pavement and watch every drop quickly soak into the specially designed asphalt, concrete or pavers.

Layers of stone or filter media below the surface create additional storage space for water. Porous pavement systems allow runoff to percolate into the ground or direct it to a storage area where it is contained for future use. Porous asphalt and concrete do require occasional vacuuming to remove particles that can clog holes in the pavement.
