Control your stormwater run-off issues
Pervious concrete is a no-fines concrete mix which is intended for use as an open-graded drainage material. The elimination of fine aggregate creates a fairly large void structure between the coarse aggregate particles, resulting in a concrete mix that is permeable to water. A typical pervious concrete mix will have a void content of 15 to 35 percent. The compressive strength for pervious concrete can range anywhere from 500 to 3000 psi.
Pervious concrete can be used for light-duty pavement in situations where it is desirable to have stormwater percolate through the pavement into the permeable base. It is particularly useful in areas where state or local regulations require that stormwater be retained on site to recharge the groundwater system.

Pervious Concrete Case Studies
- Pervious concrete allowed the addition to be built, while maintaining impervious cover limits.
- Pervious concrete was selected because it offered a life-cycle cost advantage over asphalt.
- Unique pattern and color make this pervious concrete pad stand out.
- The project featured tilt-up concrete construction as well as pervious and roller compacted concrete pavements.
- The environmentally sensitive area required a pavement solution that fit its natural surroundings
- Pervious concrete will allow potential stormwater runoff to now percolate through the pavement and into the ground
