Hardscape & Grading第 65 / 100 题
Permeable pavers differ from standard pavers because they do what?
a.Block all water from passing
b.Require no base at all
c.Are only decorative
d.Allow stormwater to infiltrate through the joints into the base and soil below
解析
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.
