Base thickness depends on subgrade, climate, drainage, and expected traffic.

How to plan it
- Ask the paver manufacturer or designer for the compacted base specification
- Measure the actual paved area and any overbuild beyond edges
- Convert compacted design volume to loose order volume using supplier guidance
Check before buying: Avoid treating one default depth as suitable for every patio or driveway.

Record your site measurements first. Then use a calculator with the depth, application rate, or coverage from the actual material specification.
