Our General All Passing 20mm (GAP20) is the go to aggregate for driveway, path and even road base courses. Very suitable for a base under pavers and concrete work. Excellent grading creates a strong stone matrix that holds its shape under heavy load and won’t slump easily (but you will need to watch that drainage)
