Pervious Concrete

Pervious Concrete

When I think of concrete I envision something solid, heavy, and impervious to water. As I was adding new contractors to the Foundations section I learned about concrete that lets water flow through it!

“Pervious concrete is a mixture of cement, water, and coarse aggregate, and little to no sand. It also frequently contains chemical admixtures. Pervious concrete creates a very porous medium that allows water to drain to the underlying soils. It is commonly produced to allow as much as five gal/ft²/min to pass through the body of the concrete.” **

Pervious Concrete can contribute to LEED credits for decreasing impervious surfaces on site, reducing the quantity and increasing the quality of stormwater runoff.
