I want to put reclaimed yorkstone flags in a random pattern on an area which will have an occasional car parked on it.
What is the min thickness of flag I can use, and what thicknesses of hardcore/ sand do you recommend?
Any other tips gratefully received.

Minimum 50mm thick (2") flags on a 10:1 grit sand:cement bed, on top of 100mm of DTp1 granular sub-base. Keep your joints approx 12-15mm wide and butter/point with a 5:1 mortar as you go.

Are you laying these yourself, Michelle, or bring in a contractor? It can be a right ball-acher trying to get reclaimed flags into a decent random pattern as they often need a good bit of re-dressing to make them fit. Have you considered using a transverse broken bond?
