Yes, you can lay natural stone pavers directly on a compacted sand and crushed rock base for pedestrian areas like garden paths and patios. However, for driveways, heavy-traffic areas, or around swimming pools, a reinforced concrete slab base is highly recommended to prevent sinking and weed growth.
Flexible Base (Sand) vs. Rigid Base (Concrete)
| Base Type | Best For | Pros | Cons |
| Sand & Crushed Rock | Patios, walkways, courtyards. | Cheaper, easier to repair, excellent natural drainage. | Susceptible to weeds, ants, and minor sinking over time. |
| Concrete Slab | Driveways, pool coping, heavy traffic. | Zero sinking, no weeds, extremely durable. | Higher upfront cost, requires proper expansion joints. |
