Enter total ft² and thickness; the tool applies the 145 lb/ft³ hot-mix density automatically.
When your driveway is already measured in square feet, this view skips straight to tons at your chosen thickness. Every extra inch of thickness adds tonnage linearly, so confirm the depth spec before ordering.
Why order extra? The headline number is the exact material your project needs. When you actually order, add about 5–10% on top — the “with 5% waste” figure in the result is a safe starting point. That margin covers what you lose to compaction, cuts around edges and corners, and ordinary spillage during handling. It is cheaper to have a little left over than to stop mid-job and wait on a second delivery.
