POROUS CONCRETE SLABS AND PAVEMENT DRAIN WATERS

Porous concrete pavement offers a way to eliminate or reduce stormwater runoff. Water simply filters through the slab and recharges the groundwater supply. Runoff volume and runoff velocity are reduced, and lag time between rainfall and runoff is increased. The result is a developed building site with runoff levels which closely approximate predevelopment runoff levels. Porous concrete pavements can be made with a porous concrete mix which contains voids that allow water to penetrate through the hardened concrete pavement. Another way to make porous pavements is to cast cavities into a slab made with normal, relatively non-porous, nonpermeable concrete. This article discusses the techniques and its application in various projects.
