Drinking water operates with the voids during the pavement for the soil beneath. Air entrainment admixtures tend to be used in freeze-thaw climates to minimize the potential of frost damage. Pervious concrete also permits rainwater to filter by means of streets and parking a lot, to recharge aquifers, instead of contributing to runoff and flooding.[92]
