We normally recommend a No. 57 gradation crushed stone or gravel, and a thickness of 8 to 10 inches. If thicker layers are used, we recommend that each 12-inch thickness of stone backfill be densified by making 3 or 4 passes of a walk-behind vibratory sled or plate type compactor over the stone surface.
