Planning guide
What is paver base?
A paver base is a compacted layer of graded aggregate that spreads loads, supports drainage, and limits settlement under segmental paving.
How this calculation works
The tool calculates base volume from paved dimensions and compacted depth. The 10% allowance helps with compaction and slight over-excavation.
Common measurement mistakes
- Calculating pavers but not the base
- Compacting one thick lift
- Using a uniform round stone that will not lock
Professional tips
- Extend the base beyond the paver edge
- Compact in thin lifts
- Maintain drainage slope away from buildings
Paver Base Calculator FAQs
What paver base depth should I use?
Base depth varies with climate, soil, and traffic. Pedestrian patios often need 4–6 compacted inches (10–15 cm); driveways generally need more.
Should I enter loose or compacted paver base depth?
Enter the required finished compacted depth. Because loose aggregate consolidates, use the material allowance and confirm the supplier's compacted coverage.
How should paver base be compacted?
Place and compact the aggregate in thin lifts rather than one thick layer. Follow the paver manufacturer's requirements for lift thickness, moisture, and compaction equipment.
