Natural Stone Paving
Quarried flagstone, sandstone, or slate cut or left irregular for patios and paths, prized for a look no manufactured product fully replicates.
Best for
- High-end patios and entry paths
- Gardens aiming for a natural, non-uniform look
- Long-term durability outdoors
Avoid when
- Tight budgets — it's among the most expensive paving materials
- Freeze-thaw climates with a porous stone type not rated for frost
Porosity determines frost survival
Some sandstones absorb enough water to crack when it freezes inside the stone. Check the specific stone's water absorption rating for your climate — not all 'natural stone' is safe in a freeze-thaw region.
Irregular flagstone needs more skilled labour
Irregular-shaped stone requires fitting pieces like a puzzle with consistent joints, which takes considerably longer and more skill than laying uniform pavers — factor that into a professional quote.
