Pervious Concrete - What is Pervious Concrete?

Pervious concrete is a mixture of coarse aggregate, Portland cement, water and little to no sand. A typical pervious (porous) concrete pavement has a 15-25% void structure and allows 3-8 gallons of water per minute to pass through each square foot. This permeable type of concrete is made with gap-graded aggregate, which means all the pieces are ...

Pervious Concrete — What, why, how? – Nevada Ready Mix

Pervious concrete is a special type of concrete with a high porosity used for concrete flatwork applications that allows water from precipitation and other sources to pass through it, thereby reducing the runoff from a site and recharging ground water levels. The high porosity is attained by a highly interconnected void content.
