The subgrade should be properly compacted to provide a uniform and stable surface. As with any concrete pavement, proper subgrade preparation is important. HOW to Create Pervious Concrete Pavement?Īn experienced installer is vital to the success of pervious concrete pavements. A pervious concrete pavement allows the transfer of both water and air to root systems allowing trees to flourish even in highly developed areas. Pervious concrete can also reduce the impact of development on trees. All of these benefits lead to more effective land use. Pervious concrete functions like a storm water retention basin and allows the storm water to infiltrate the soil over a large area, thus facilitating recharge of precious groundwater supplies locally. Pervious concrete also naturally filters storm water and can reduce pollutant loads entering into streams, ponds and rivers. This allows property owners to develop a larger area of available property at a lower cost.

Pervious concrete reduces the runoff from paved areas, which reduces the need for separate storm water retention ponds and allows the use of smaller capacity storm sewers. As regulations further limit storm water runoff, it is becoming more expensive for property owners to develop real estate, due to the size and expense of the necessary drainage systems. Environmental Protection Agency (EPA) for providing first-flush pollution control and storm water management. The proper utilization of pervious concrete is a recognized Best Management Practice by the U.S.

It is an important application for sustainable construction. Pervious concrete is traditionally used in parking areas, areas with light traffic, pedestrian walkways, and greenhouses. Typically pervious concrete has little to no fine aggregate and has just enough cementitious paste to coat the coarse aggregate particles while preserving the interconnectivity of the voids. The high porosity is attained by a highly interconnected void content. 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.
