Pervious Concrete

Pervious Concrete is a fantastic environmentally green choice for those who want a less expensive and environmentally friendly option to manage storm water.  This porous concrete mixture has little to no sand which creates an open-cell structure that allows rain water to filter through to the underlying soil!  According to the United States Environmental Protection Agency (EPA), storm water runoff can send as much as 90% of the pollutants (such as oil and other hydrocarbon liquids commonly found on parking lot and driveway surfaces) directly into our rivers and streams.  The Pervious Concrete filters the water giving enough time for the pollutants to break down before they meet our streams and rivers.  The use of Pervious Concrete can reduce the need for large detention ponds, skimmers, pumps, drainage pipes and other storm water management systems.  Expensive irrigation systems can be downsized or even eliminated.  Pervious Concrete is a durable material; parking areas properly designed and constructed will last 20-40 years with minimal maintenance.  Thus, concrete, conventional or Pervious, is widely recognized as the lowest life cycle cost option available for paving.

Entire road drains directly into the pervious sidewalk; the catch basins never see water.

Here are some different stages of placement and what the final product looks like during all four seasons.

The surface of fresh Previous must be covered within 20 minutes of placing it.

We always cross roll through 2 ml poly. This produces the best finish and starts the curing process more quickly. After cross rolling the white 6 ml poly is placed over the top.

Curbing is usually only installed to keep people from driving off the edge of the pavement. Here is the finished product with a concrete curb.

Water from the garden hose disapears into the Pervious Concrete.

Pervious covered up with plastic so it can properly cure for 7 days.

A closer view of the Pervious Concrete in our yard. 80,000 pound trucks enter our yard every day, occasionally 100,000 pound loads go across it!

Extreme close up. The ground below the Pervious doesn't freeze as much as it does under asphalt. The asphalt has heaved up to 1" more than the concrete. The surface looks rough but is surprisingly smooth to the touch.
