Calculation assumptions
  • Paver base density: 1,850 kg/m³.
  • Bedding sand density: 1,600 kg/m³.
  • Base depth is finished compacted depth; 15% volume loss is applied before overage.
  • Sand depth is a uniform finished screeded layer and receives overage but no compaction multiplier.

Layer-by-layer math

Why base and bedding sand stay separate

1

Finished volumes

Area is multiplied by each finished layer depth.

2

Base compaction

Base volume is divided by 1 − compaction loss.

3

Order quantities

Overage is added and each material rounds up independently.

Bedding sand receives overage but no separate compaction multiplier. The base uses 1,850 kg/m³ and sand uses 1,600 kg/m³ for approximate weight.

Required excavation, base thickness, geotextile, drainage, and sand thickness depend on soil, climate, loading, and the paver system. Confirm the section before ordering.
