Formula and assumptions
General ranges are educational only. Actual thickness depends on loads, soil, reinforcement, drainage, climate exposure, site conditions, and applicable codes.
General thickness guidance
| Application | General starting range | Important note |
|---|---|---|
| Sidewalk / walkway | About 4 inches | Local requirements and loading may differ. |
| Patio | About 4 inches | Soil, edges, climate, and use matter. |
| Residential driveway | About 4–6 inches | Vehicle loads and base conditions matter. |
These are broad educational examples, not engineering specifications or approval of a particular design. Verify applicable codes and site requirements.
