What is Pervious Concrete?
Pervious concrete is a porous concrete paving material which permits rain and storm water runoff to percolate through it rather than flood surrounding areas or storm drains. It is usually a mixture of 3/8” to 1/2” average diameter aggregate, hydraulic cement, other cementitious materials, admixtures and water. When properly placed, pervious slabs will contain voids that would be filled by sand. Like a honeycomb these voids are held together with cement. These irregular voids thus add great strength to the slab. Our designed pervious mixture is the result of over 25 years experience. When cured it resembles popcorn slabs.
Pervious Concrete (PC) is not to be confused with Roller Compacted Concrete (RCC). Roller Compacted Concrete is an Impervious Concrete pavement using recycled concrete, local aggregates, Portland cement and water. RCC prevents storm water from reaching the aquifer.

Though it is available from many concrete plants, the engineered mixture is only one key ingredient to a porous paving system.
