Permeable pavers, also known as porous concrete, porous pavement, gap-graded concrete, or enhanced porosity concrete, are comprised of concrete bricks, separated by joints, or gaps, filled with small stones or sand, which are laid over a bed of aggregate stones. Water is able to infiltrate through the joints in the pavers, and is stored in void space underneath the paver surface, where it is then filtered back into the soil. These pavers also allow designers to maximize the building footprint in areas that have a maximum impervious to pervious ratio.
