Borderline volume. Mixing is doable with a mixer and a crew; ready-mix saves labour and gives a more consistent pour. Compare quotes, including short-load fees.
Metric: m³ = length (m) × width (m) × thickness (cm) ÷ 100.
| Use | Thickness |
|---|---|
| Walkways, patios, shed bases | 4 in (10 cm) |
| Driveways (cars) | 5 in (12–13 cm) |
| Garage floors, RV pads | 6 in (15 cm) |
Every extra inch of thickness adds 25% more concrete to a 4 in slab — so check your excavation depth before ordering. Low spots in the subgrade are the most common reason pours come up short.
