Hello! First post so apologies if I'm in the wrong section but I figured this'd be a technique of sorts...
Along the back of my garden I have a row of slabs which I would like to remove and replace with decorative stones and some little shrubs.
The issue is, underneath the slabs there is a good 3 inches of concrete, I reckon I could probably get it out with a breaker but this'd mean also having to get a skip (which is expensive).
The only other option (I can think of) would be to chuck a load of compost/soil over it, I do have quite a bit kicking about as I have just finished doing my front garden.
The downside of that would be the new area (what was previously under slab) would be higher than the grass level, which would cause a rubbish edge and not really look as nice.
What sort of depth of soil is necessary for little shrubs?
If anyone can see a better way of doing this please share!
