Permeable Pavers
Permeable interlocking concrete pavement (PICP): Solid concrete pavers with small, stone-filled joints that allow water to flow into highly permeable, open-graded bedding, base, and subbase aggregates. The spaces among the aggregates store water and enable its infiltration into the soil subgrade rather than generating surface runoff. The paver joints provide 100% surface permeability and the aggregates filter stormwater and reduce pollutants.
