I've dug out a big hole as my pictures show. I'm going for a 10ft x 8ft shed. I need to build a retaining wall at the back of the site too to save the fence collapsing. Though the fence does belong to me, and I had toyed with demolishing it and building the shed on the property line (as I'm doing round the corner).
Will I be ok building my retaining wall on my shed slab? Then framing the shed around it? I'm going to use breeze blocks laid flat with gravel infill. May also use a french drain or similar.
I've dug a shovels depth (about a foot) though I've yet to level it out to a uniform depth.
Is it MOT type 1 I need for the base? Then all in ballast and cement for the top. What qty of each of these products am I likely to need? If I do 100mm of each its 0.72 cubic metres each.
With the MOT I don't have a compactor, does it really need this? Could i just use a plank and jump about on it for an hour?
Incidentally would a ready mix company deliver such a quantity? If I had to round it up to a cube I'd find somewhere for it to go or just lay the shed base deeper (140mm is 1.008cubic). And any idea on price in Rotherham? Only problem with ready mix is access - the roadside is a good 25 metres away and there's nowhere to tip it on my property. The thought of mixing up all that concrete fills me with dread. I dont have a mixer.
The soil is going to the builders doing the extension at the house behind - a stroke of luck!
