How much base is needed for a paver driveway?

• A. 8 to 12 inches
• B. 1 to 3 inches
• C. 4 to 6 inches
• D. 12 to 24 inches

Answer: (A)

The main idea is that the base provides the load-bearing support and stability a paver driveway needs. A thick, well-compacted base distributes the weight of vehicles, resists settlement, and helps prevent cracking from frost and soil movement. Eight to twelve inches is recommended because it offers enough mass to handle typical driveway loads, even on soils that are soft, clayey, or prone to frost heave. This thickness keeps the surface level and durable over time, especially in climates with freeze-thaw cycles or when heavy traffic is common. For context, the base is usually made of compacted crushed stone or aggregate, laid in layers and compacted thoroughly before the sand bedding and pavers go on. If you have excellent, well-drained soil and light vehicle use, you might get away with less, but for a solid, long-lasting driveway, 8–12 inches provides the needed stability.
