b.Require no base at all
c.Are only decorative
d.Allow stormwater to infiltrate through the joints into the base and soil below

Permeable pavers are set with open, aggregate-filled joints over an open-graded stone base so rainwater infiltrates rather than running off. This reduces runoff volume and helps recharge groundwater, supporting stormwater regulations. They require a specially designed base to store and drain the water.
