Drinking water runs through the voids in the pavement into the soil beneath. Air entrainment admixtures will often be Utilized in freeze-thaw climates to minimize the opportunity of frost problems. Pervious concrete also permits rainwater to filter by means of roads and parking a lot, to recharge aquifers, as an alternative to contributing to runoff and flooding.[92]
