What's the difference between 22mm and 18mm calibrated paving?Updated 2 months ago

22 mm calibrated paving is the thicker option and generally offers greater strength and durability. 18 mm calibrated paving is a thinner, more budget-friendly option while still providing consistent thickness for installation. Both types are machine-calibrated, but a small thickness tolerance is normal with natural stone. Typically, this is around ±2–3 mm.
