Compaction
Compaction is the process of making soil or other materials more dense and stable by pressing them together. In landscaping, it's an essential step that ensures the ground won't settle or shift after construction work is done. Think of it like pressing down on a sponge - the process removes air pockets and makes the surface firmer. This is crucial for creating sturdy foundations for patios, walkways, or preparing ground for lawns. Landscapers use special machines called compactors (sometimes called plate compactors, tampers, or soil compactors) to do this work efficiently.
