Pervious Concrete
Pervious concrete is a low-slump mixture that, after hardening, contains many voids that allow water to flow through easily. The result is a concrete pavement that reduces the rate and quantity of runoff from stormwater or snowmelt. BASF offers admixtures that solve the low slump mix challenges traditionally associated with pervious concrete.
Why it's a sustainable technology
LEED Credit Contribution Potential
-
Pervious concrete is considered a Best Management Practice (BMP) by the EPA, and federally mandated regulations have characterized it as a viable solution for stormwater management
-
May contribute to earning LEED credits in the Sustainable Sites category, Credit 6.1 - Storm Water Design, Quantity Control - 25% Reduction (one possible point), Credit 6.2, Storm Water Design, Quality Control - Limit Disruption and Pollution of Natural Water Flows (one possible point), and Credit 7.1, Heat Island Effect, Non-Roof (one possible point)
How it works
Because pervious concrete is a relatively dry mixture, concrete producers and contractors face production and placement challenges. The admixture system for Pervious Concrete from BASF helps overcome these placement challenges by:
-
Promoting easy discharge from ready-mix truck
-
Eliminating the need for addition of water on site
-
Increasing workability time
-
Improving mix flow for easier placement
-
Increasing compressive strength
-
Inhibiting paste drain down
