In the past, I have used a concrete footing for any retaining wall brickwork
that I have layed in the garden.
I'm now building my flower beds using cobble stones as the edging. The
Stones are 8" high by about 6" wide by about 14" long and extremely heavy,
and in total the perimeter is about 20 foot.
I'm not too bothered about having the tops exactly straight, but I dont want
them settling into an uneven mess.
I can think of 3 ways to provide a bed for them.
1) Concrete footings and then cement them in place
2) A sharp sand bed and sit the cobbles in place
3) Sat straight on the (claylike) soil.
Because the cobbles are so sturdy, I can't help thinking number 1 is a bit
overkill, and I'm tempted to go with option 2.
Do any of you guys have any thoughts/advice/other solutions
