The Anatomy of Permeable Paver Construction
PICP comprises a layer of solid concrete pavers separated by joints filled with small stones. Water enters the joints between the pavers and into an “open-graded” base-crushed stone layer with no small or fine particles. The void spaces among the crushed stone store water and infiltrate it back into the soil subgrade. The stones in the joints provide permeability, and the base filters stormwater and helps reduce pollutants.
