Can you pour concrete directly on dirt?
Pouring concrete directly over dirt or sand is generally not recommended for creating a stable and durable foundation. A proper foundation for buildings typically requires excavation, the installation of a suitable sub-base, and the use of reinforcing materials like rebar or mesh. Concrete site preparation or “dirt work” can involve various activities, including excavation, grading and compaction. Good site preparation is essential to ensuring that your concrete project is a success.
