I'm looking to lay gravel in my garden. Its a concrete base with problems of weed. Its not 100% level and slightly cracked at few points.
I have been told to lay a membrane cover to deal with the weed problem, but do I just lay the gravel on top of the cover or am I required to prepare a layer of hardcore, sub base etc. If yes, in which order do I lay them, eg: 1: cover, 2: hardcore, 3: sand, etc etc
I also want to place stepping stones in the garden with the gravel around but would like some advice on how to do it with the cover below it etc
Please please please can you help. Many thanks
