I am planning a gravel path for the garden and the plan is to edge it with 100mm granite cubes, one edge being against the lawn (finishing 4-5cm above lawn level). Gravel will finish at same level as lawn so setts contain it (hopefully)!
Just have 2 questions:
1) Regarding bedding material for the setts, should the concrete mix be just sharp sand & cement or should I add a fine (10mm) aggregate too? Seems from the website that either can be used?
2) The channel I have dug is just over 150mm deep. Would it be best to lay the concrete for bedding directly onto sub grade/ soil below to give a good 100mm depth below the setts or should I lay a thin layer hardcore first then concrete approx 50mm on top of this? Either way I will then top up the hardcore to 100mm for the gravel.
