I wouldn't like to hand batch and lay 3 cubes, that's 7 tonnes of concrete.
OP: why are you choosing C20? Not a very strong mix. ____________________ a.k.a 'Geri'

We have it delivered by volumetric mixer all the time, though not with the integrated pump, never even seen one of those.
First consideration is that those wagons are VERY heavy - over 40 tonnes and they have a high ground loading because they are very squat. Just look at the tyres on the one in the video. They'll sink the pavement, collapse drains and get stuck in even medium ground so consider the access very carefully if you're going to use one.
Dunno how happy Northvale would be with that video showing them running suspended hoses across a public footway AND washing them down into a watercourse. That's a big no-no. ____________________ a.k.a 'Geri'

Not many suppliers will have the pump integrated, they'll tell you that you have to hire a pump (which is another big lorry plus operator and a good few hundred quid for half a day). I don't know of any anyway.
Laying 3 cubes as a slab you're going to need joints anyway so don't worry about that. ____________________ a.k.a 'Geri'

Been there, done that. It's not that difficult but it does give you a decent workout. Here's a picture - there's another pallet off camera. I had to move it 50m - I decided to barrow it after mixing.

You're doing hardcore, wacker, blinding, wacker, DPM first, right? |
I was going to dig out, tamp the soil with a steel-headed tamper that BT thoughtfully gave to me, and just go on that. The soil is free-draining, firm, and slightly gritty, and it hasn't been touched for 30 years at least. I might go a bit thicker than 100mm but not a lot. |

Oh! I'm not confident about anything! I'm learning a bit though, which I'm always interested in....
I was wondering about DPM. Is the purpose to stop the concrete drying unevenly, or to be an actual DPM? I had an unfortunate camping trip once, when my dad, with the best of intentions, pitched our tent on a big bit of DPM he'd got left over. It rained. The rain ran very quickly inside, rather than being able to drain away. I wouldn't want my slab to be effectively inside a paddling pool like that!
Bitumen emulsion DPM on top, with laminate floor over? A friend has a huge pile of good laminate floor he might part with.
Any ideas or observations most welcome. |

DPM is for under the slab to isolate the slab from the ground during curing and afterwards. No need for any other membrane so long as your ground level outside is all below the slab level.
If your garage is 6x5 then 6.1x5.1 is not big enough. Add at least 250mm each way IMHO and be very sure you have it staked out square. ____________________ a.k.a 'Geri'

Because some of it is being dug in to the slope, the best way of doing it may be to dig out an area larger than you think you need, then retain the exposed verticals with blockwork. You can then lay your slab with finished floor level a few mm above the ground on the elevation containing the doors. I'd fill the gap between the retaining element and the slab with gravel because it drains well.
Alternatively, to avoid having to pour extra concrete for your retaining element, you could go for a bigger slab and build your blockwork straight off it. Depends how much you have to do....
One thing to watch - irrespective of whether the building itself needs planning permission, if the Council finds out that you have plant on site (even a Bobcat), it can describe the works as an 'engineering operation' which needs planning permission by virtue of this alone. In all discussions with the Council, be it Planning or Building Control, say that you will be hand-digging.... ____________________ Now - Speed Triple, old ratty GS550, GSXR750M
