Probably a question for @ColinTheBald: I'm thinking of doing the gravel board path thing, or maybe just pour my own slabs as then make them look a bit more interesting. What can I use as a sub base considering I want to plant things in the gaps. I'm guessing it needs to be permeable, so in theory type 3? But it appears to be kind of impossible to actually buy that anywhere.
They're so heavy and broad I'd assume just some type 1 under each slab would do it? Main thing I guess you need is to get them level and at the right depth
