Pervious concrete is a type of concrete with little to no fine material that allows water to pass through it. It is made using the same methods as conventional concrete but with an open graded aggregate structure. Pervious concrete undergoes various lab tests to determine properties like slump, air content, permeability, and strength. It has many applications where drainage is important such as sidewalks, roads, parking lots, tennis courts, and pool decks.
