hi all
I have recently had a new fence installed and the next plan is to level out the garden which will mean raising the drop by around 600mm. The fence is 8.8m long. I cannot decide which would be the best way to retain the garden. It won't be seen as its against my fence and the other side will be under 2ft of soil!

first option I was considering was compacting the soil with a roller and putting down 200mm of gravel and laying 200x100x2.4m new treated sleepers rebared and screwed together brick style. This would be 6 sleepers high. Membrane and gravel behind and drainage pipe. Cost on the sleepers alone seems to be coming out around £450 for 30 or so.
2nd option I looked at is the same sleepers chopped in half to 1.2m and buried 40% in dry mix concrete. Rest following above. Cost seems to about the same but I have a number of trees so it could be very hard work!
3rd option I considered 200mm medium density blocks laid on there side on a 300mm gravel base. Seems to be cheaper but not sure it would take the weight?
Basically I am looking for something cheap that will last and it doesn't matter what it looks like as I won't see it. Any ideas?
