Pervious Concrete, The Basics — Bay Area Pervious Concrete

Pervious concrete is a durable concrete pavement with a large volume (approx. 20%) of interconnected voids. Like conventional concrete, it is made from a mixture of cement, coarse aggregates, and water. However, it contains little or no sand, which results in a porous open-cell structure that allows water passes through readily.

Typically, the benefits of using crushed aggregates outweigh the advantages of rounded aggregates when considering bond and strength. The needed amount of cement paste is dependent upon the amount of aggregate voiding that must be filled and the surface area that must be covered. With poorly graded aggregates, the voiding is the greatest.
