Pervious concrete technology

Also known as no-fines or low fines concrete, pervious concrete is a mix of portland cement, coarse aggregate, water and admixtures. Because there is little or no sand in the mix, the pore structure contains many voids that allow water and air to pass through easily.

Pervious Concrete Advantage: 

Federally mandated storm water management regulations that are in effect have made pervious concrete systems a viable solution. In addition to the EPA's recognition of pervious concrete as a Best Management Practice (BMP), building owners are also achieving better land utilization and LEED credits with pervious concrete parking lots. Pervious concrete applications can be used as an alternative to complex drainage systems and water retention areas for reducing storm water runoff.

Pervious Concrete Admixture System from BASF:

To overcome the challenges associated with the production and placement of pervious concrete, BASF, under the Master Builders Solutions brand, has developed a system of admixtures for concrete producers. This innovative combination includes MasterGlenium or MasterPolyheed high-range water reducers, MasterSet DELVO hydration control admixture, and a MasterMatrix viscosity-modifying admixture.

The admixture system:

1. Improves ease of discharge from the truck

2. Increases working time with improved concrete flow

3. Overcomes placement challenges

4. Increases compressive strength and optimizes effective voids

5. Inhibits paste draindown

Pervious Concrete Applications:

  • Parking lots
  • Driveways
  • Sidewalks/walkways
  • Streets/road shoulders
  • Other light traffic areas
