Pavers/ Permeable Pavers
Driveways, parking lots, streets, ports and airports with interlocking concrete pavements enable easy access for base and subsurface utility maintenance. Repairs are simplified by removing the paving units, making the repair, and then replacing the same units without creating unsightly patches. The pavers maintain a visually and structurally consistent surface. Pavement surface life is not reduced because there are no damaging cuts into it.
Permeable interlocking concrete pavement (PICP) is comprised of a layer of concrete pavers separated by joints filled with small stones. Water enters joints between solid concrete pavers and flows through an "open-graded" base, i.e. crushed stone layers with no small or fine particles. The void spaces among the crushed stones store water and infiltrate it back into the soil subgrade. The stones in the joints provide 100% surface permeability and the base filters stormwater and reduces pollutants.
