Suitable ground for flags

[pc6844]

Hi, can you use all in one ballast as a base for concrete flags? The flagged area is just to put a metal shed on?

Many thanks

you can lay slabs on a concrete mix,You can buy dry bags of it at your local builders merchants, but add some cement to it,lay it on the ground dry and then lay the slabs,the moisture in the ground will set it
