What Is Pervious?

Concrete that water can run through!

A paving material that acts like a grassy field ... in a way.

               Like grass, it allows the ground below it to breath, allowing tree roots and their supporting microbes and fungus to interact.

                It is a mixture of coarse aggregates, hydraulic cement, cementitous materials, admixtures and water.

                It contains no sand, but relies on strong, cohesive, hydraulic Portland cement for its integrity.

                Because of its open cell structure, it has more strength and crack resistance when used for paving, than an equal weight of impervious solid concrete.

Used as a "dual-use" product, it meets the demands of the EPA -Clean water Act.
