I am designing some paths and paving areas in MIL's garden.
I am using brick-sized pavers in a course 4 bricks wide, which will be bordered by cobbles set in mortar.
I am debating whether to set them just on a sharp sand base, or whether to put down a few inches of hardcore first.
MIL's garden has a light, sandy soil and is very level. The ground where I am laying the paths has not been disturbed for decades, so I do not anticipate any settling issues. The paths will get light use only.
There will also be two small paving areas- about 3 meters by1.5 metres each.
Obviously, the sand only option would be cheaper and easier to do, but I know that there is a risk of the paths becoming uneven if I don't use hardcore.
Does anyone have experience of either method, or have any recommendations?
