Pervious concrete is a porous material that is made up of a large volume of interconnected voids. Created using little to no sand, cement binds stone together to create an open-cell system.
Pervious concretes has many benefits that function in saving our environment. Its design allows for rainwater to pass through and into to the ground, reducing storm water run-off and preventing flooding and erosion. Its filtration process actually helps purify the water and prevent runoff pollution. Pervious concrete can eliminate the need for traditional storm water management systems such as retention ponds and sewer tie-ins since it doubles as a water retention structure.
Pervious concrete is most frequently used for parking lots, sidewalks, patios and other paved paths. It is also used for streets, driveways and pool decks.
