Our 20mm Brown Crushed Rock is a 20mm stone down to fines that compacts to a hard surface. It is suitable for driveways, pathways, under paving and concrete slabs as its main function is to create a stable compacted base. For the best result, we do recommend once laid that crushed rocks are compacted by either a water roller or vibrating plate. Crushed Rock is commonly laid between 50mm - 150mm depth. *Please note that all of our bulk products are sourced from natural sources. There can be variation in the product due to their natural occurrence. We recommend looking in-person to get the best impression of the product before ordering.
