What happens here
Once the sub-base is compacted, a layer of crushed stone aggregate is brought in and spread over the entire patio area. The compact utility loader is efficient for bringing in and rough-spreading large quantities of gravel. Workers then use rakes and shovels to meticulously level the aggregate to the desired thickness and grade, preparing it for compaction. The exact thickness will depend on the final patio material (e.g., pavers usually require 4-6 inches of compacted base).
Goal: Lay down and level the crushed stone aggregate base.
