Base material is the foundation layer used in landscaping projects, typically consisting of crushed stone, gravel, or similar materials. It's placed underneath features like patios, walkways, or driveways to provide stability and proper drainage. When reading resumes, you might see it referred to as "aggregate base," "crushed stone base," or "gravel base." Think of it as the hidden but crucial layer that prevents expensive problems like sinking or cracking in outdoor installations. It's similar to a building's foundation - while not visible in the final project, it's essential for long-term success.
