what a thread
My option would be just take the floor out and lay on slabs, any condensation on the tank will drain away under the slabs, afterall your not going to live it, its only for a IBC
LOL,.. someone talking sense at last!!!
If you want to go mad, lay a concrete slab,.. 4" thick is plenty if you use readymix, 6" thick if you are foolish enough to try and mix that much yourself. Make the slab slightly raised in the centre, so spills will drain off round the edges, and make the slab slightly smaller than the shed, so the walls sit down over the slab, keeping it completely hidden and out of the weather.
Making a shed would prob be a good idea too,.. those heaps of firewood you get from B&Q are a pain to put together and are way too flimsy IMO. It'll prob cost you a little more to build your own, but it'd be worth it. Slap a waterproof membrane inside the walls,.. some polystyrene insulation,.. wire a few sockets in, a light and maybe a bit of heating,... and make sure its big enough for the bar and snooker table as well as your IBC!!
