The density of pervious concrete depends on the properties and proportions of the materials used, and on the compaction procedures used in placement. In-place densities on the order of 100 lb/ft³ to 125 lb/ft³ (1600 kg/m³ to 2000 kg/m³) are common, which is in the upper range of lightweight concretes.
