before i ask the questions i should set the scene. I have a space of around 14m2 that i wish to cobble/pave. However there are 2 raised garden beds and many round posts supporting retaining walls in the area to be paved. I have retained the area i wish to pave and am ready to start the ground prep.
What i was thinking of doing was rather than cutting paving stones and then laying them, building box section and casting pavers onto the prepared ground (so i could shape them around all the obstacles) it would be like laying a path but i would want to cast them into a uniform square pattern for ease of installation and cost saving, also to look a lot nicer than a concrete pad.
My questions are:
1. If my pavers are to be 450 x 450, what depth should the paver be.
2. What depth should i make the sand bed to lay them on??
3. if i am to cast my own pavers then what mix should i use. Will an 1:8 (cement : builders mix) be suitable and also come up with a nice finish. Or should i move into a more 1:2:3 (cement : fine stone chip : sand).
4. if i was to add a coloring additive to the mix, how hard is it to keep it even between batches of concrete that i make.
any thoughts or help would be appreciated.
Cheers.
