Compacting is the process of pressing soil, aggregate, or base material to remove air pockets and increase density. This is a crucial step in preparing the ground for construction or hardscaping projects, such as installing pavers, concrete slabs, or retaining walls. Compacting helps create a stable and level surface, reducing the risk of shifting or settling over time. Specialized tools like plate compactors or tampers are commonly used to achieve the desired level of compaction.
