Paver Sand & Gravel Depth Calculator
Here’s a basic table that outlines recommended depths for paver sand and gravel when constructing a paver patio or walkway. This is a general guide that can be adjusted based on specific project requirements.
| Layer | Recommended Depth | Material | Purpose |
|---|---|---|---|
| Subgrade | N/A (existing soil) | Compacted soil | Stable foundation, typically compacted. |
| Base Layer | 4″–6″ (10–15 cm) | Gravel (crushed stone) | Provides drainage and structural support. |
| Bedding Sand | 1″ (2.5 cm) | Paver sand | Leveling layer for pavers, also helps lock them in place. |
| Pavers | Varies (usually 2″–3″) | Paving stones | Surface layer. |
| Joint Sand | Fills gaps between pavers | Polymeric sand | Stabilizes pavers and prevents weed growth. |
Notes:
- Base Layer: Crushed stone such as limestone or granite (gravel) is typically used. Ensure it is compacted to prevent shifting.
- Bedding Sand: Use coarse sand to create a smooth surface for laying pavers.
- Joint Sand: Polymeric sand is often used because it hardens when wet, keeping pavers secure.
