Pervious pavement

Pervious pavement (also called porous concrete, permeable concrete, no fines concrete and porous pavement) is a special type of concrete with a high porosity that absorbs rainwater and allows it to pass through it down into the underlying soil,  thereby reducing the runoff from a site.
