Materials for a 20×20 paver driveway
| Item | Quantity | Notes |
|---|---|---|
| Paved area | 400 sq ft | length × width |
| Pavers to order | 428 sq ft | 7% extra for cuts and breakage (1,142 pieces if you use a 6 × 9 in paver) |
| Base: crushed stone (2A modified / crusher run) | 20.7 tons | 10 in compacted in 2–3 in lifts, the minimum for cars |
| Bedding sand (concrete sand) | 2 tons | 1 in, screeded, never compacted before the pavers go down |
| Polymeric joint sand | 7 bags (50 lb) | about 60 sq ft per bag on standard joints |
| Edge restraint | 80 ft | all the way around, spiked every 12 in |
| Filter fabric under the base | 460 sq ft | keeps the base out of the soil |
| Soil dug out | 22.7 cu yd | about 14 in deep, plus room for the base to extend 6 in past the pavers |
Quantities use common rules: crushed stone at about 1.4 tons per cubic yard plus 20% for compaction, concrete sand at about 1.35 tons per cubic yard. Your stone yard can convert to their product. Base depths assume normal soil in a freeze-thaw climate; soft or wet soil needs more.
Good to know
- Room for two cars side by side. A driveway needs a thicker base and a thicker paver than a patio; this is where cheap installs fail first.
- When a paver job fails, it is almost always the base, not the pavers. The stone in the list above is the part not to skimp on.

How much does a 20×20 paver driveway cost installed?
We build a 20×20 paver driveway in central Pennsylvania for about $13,750 ($34 per sq ft), including excavation, base, materials and cleanup.
