Cover the excavation with a 6-inch layer of ¾- to 2-inch washed crushed stone, which has sharp edges that knit together. (River gravel, with its rounded profile, is unacceptable.) Go over it twice with a plate compactor, across and lengthwise. Top with one 4-inch layer of ¼- to 1½-inch washed crushed stone, and compact that twice, too.
