¼-” (Quarter Minus): Quarter Minus is crushed rock with sizes from ¼” down to dust. It is our “go to” for base material underneath pavers and small to medium sized retaining walls. ¼- will compact well and also can be leveled so that pavers can be placed on this base without the need for a leveling layer of sand. We recommend about 3 inches of compacted base for most patios and small to medium sized walls. For driveways, we recommend 4-6 inches.
